Cartoon Ernie still can't figure out the correct amount of window opening. He must have five years in on it by now. :D

On this model, the window is now raised 20". Appears to be some tweaking left to do. The model's line-of-sight to the window is not exact to that of the Dillard photo. But better than Cartoon Ernie.

Shadow supposedly represents shadow at 12:30, Nov. 22, 1963. SketchUp doesn't permit shadow to show on transparent material unless the transparency is a rather dense setting. So the surface of the window glass exhibits no shadow. SketchUp is a pretty low-budget entry-level program so some limitations occur.

Details and measurements in this model probably won't work in other models.

Jerry, did Stephen Fagin provide some actual measurements of the individual bricks around the window? Or is my memory playing tricks on me?

Jerry, did Stephen Fagin provide some actual measurements of the individual bricks around the window? Or is my memory playing tricks on me?

An assistant measured an exterior brick on the ground floor. I accidentally deleted that email, but one of my graphics says 2 3/16" H x 3 7/8" D x 8 1/4" L with a 1/2" mortar. I used that for awhile but my window ledge height exceeded 60'. Changing the brick height to 2 1/8" made quite a difference for me (I kept the 1/2" mortar). Now some standard modern bricks are 2 1/4" high, so one could play around with that by using a slightly smaller mortar. I don't see hardly any variation in the individual brick height.

Curator Fagin measured the masonry opening in which the frame for the SN window set sits in, and was very close to Lt. Day's 8' 2".  Day's measurement is what I use for the masonry opening.

In 2019 I made quick measurements of south face bricks as 43" L and 13" H for runs of 5 brick and 5 mortar. I did not record fractional inches, if any. I will recheck when I can get back to big D.

Anyone with a brain knows that Oswald could not have pulled off the feat with the gun they found up there. He would have had to assemble the gun [no proof or witnesses saw this happen] after bringing it in, and he would have had to sight and align the scope. There's no way he could have pulled all of this off AND made perfect shots in 6 seconds when many shooting experts couldn't pull off the same sequence under controlled settings.

How did that car get to the 5th-floor level and the rifle tracking angle would have snuffed Brennan; no problem.

But at least Ernie remembered to get his dummies dressed. And lest we forget, Canadians saved his country's sorry arse from having to learn German.

What Oswald Apologists don't want to Hear

Shooting the 6.5 X 52 mm, 7.35 x 51mm Cartridges and the Carcano Rifles,
an article by Dave Emary, Senior Ballistician of Hornady Manufacturing

____________________________________________________________

The 6.5 X 52 mm cartridge has taken a great deal of criticism as being
underpowered and anemic. From a ballistic standpoint this is a little hard
to justify. The Swedish 6.5 X 55 mm cartridge is considered an outstanding
cartridge yet it is only able to produce 100 fps more velocity with a
156-grain bullet in the M96 rifle. The 6.5 X 55 requires a maximum average
pressure of 55,000 psi and approximately 6 more grains of powder to
produce this meager gain in performance. The . 30-30 Winchester, regarded
as an adequate deer rifle and known to have killed many moose and bear
produces 2,220 fps in a 24” barrel with a 170 grain bullet. The 6.5 X 52
mm fires a bullet with a higher ballistic coefficient, at a higher
velocity, shoots flatter and has far more penetration capability than the
.30-30. From the standpoint of a service rifle cartridge the 6.5 X 52 with
its relatively low operating pressure, coupled with its modest powder
charge would result in much less barrel throat erosion and wear. This
would equate to longer barrel life and decreased operating cost. In fact,
much of what was done in the Carcano rifle/ammunition system was aimed at
long barrel life, as will be shown later. From my point of view the 6.5 X
52 is a very efficient cartridge, offering adequate performance for what
it was intended.

The only fault that one might level against the 6.5 X 52 as a military
cartridge is that it had relatively humane terminal ballistics. The very
long, blunt nosed bullet coupled with the fast twist rate of the gun
resulted in a bullet that was very stable with a very high resistance to
tumbling. The cartridge was known to have inflicted many “through and
through” wounds, just leaving a small wound channel. The bullet
typically would not tumble inside its’ target unless it encountered
something hard such as bone. When it did tumble the wounding effect is
well known.

____________________________________________________________


The original 6.5 X 52 mm Carcano design used a gain twist barrel. The gain
twist results in a very slow initial twist in the barrel progressively
getting faster until the full twist rate is attained at the muzzle. The
slow initial twist results in substantially less torque being imparted to
the bullet during the highest loading phase of the interior ballistic
cycle. This results in significantly less barrel wear in the throat. This
coupled with the very deep rifling of the barrel would result in barrels
that would have a very long wear and accuracy life. This in fact is the
case. Many M91 model rifles show signs of considerable amounts of
ammunition being fired through them, because of the crazed/frosted
condition of the bore, yet still show very strong rifling and shoot well
with the proper size bullets. The 7.35 X 51 mm Carcano rifles used a
standard fixed twist barrel. The Carcano bolt is the model of a simple,
easy to field strip bolt. It is about as fool proof as you can get for a
common soldier. The Carcano trigger has taken a considerable amount of
criticism. The trigger is basically a Mauser type two-stage trigger. In
almost all cases if you find the trigger rough or creepy simply polishing
the sear and trigger mating faces result in a very acceptable trigger for
a military rifle. For the most part I have found Carcano triggers have
less creep, are more crisp and lighter than the majority of Mauser
triggers I have encountered.

The materials used in the Carcano are excellent. These rifles were made
from special steels perfected by the Czechs, for which the Italians paid
royalties. If you have ever tried doing any work on a Carcano receiver you
will find out just how hard and tough the steel is. The Carcano has also
received a reputation as being a “weak” design. Nothing could be
further from the truth. The Italians made a small run of Carcanos early in
WW II chambered for 8 X 57 JS. The Germans rechambered some Carcanos to 8
X 57 JS late in WW II. These rifles were also proofed for this cartridge.
The CIP minimum suggested proof pressure for the 8 x 57 JS cartridge is
73,500 psi. I hardly call this a weak action.

____________________________________________________________

The Italians apparently realized that a 300-meter battle zero was a bit
impractical and with the introduction of the M38 models went to a 200
meter battle zero. This zero results in a maximum height of trajectory of
5.5” – 6.5” at a range of approximately 100 yards, depending on
barrel length. With this sight setting, by simply holding on the middle of
the torso, it would have been hard to miss the target out to about 220
meters. The Carcano’s also used a unique sight picture. The proper sight
picture for regulated sights on a Carcano is with the front sight in the
very bottom of the rear sight groove. This is how the Italian army manuals
instructed that the sights be used. Potentially, this would allow for two
battle sight settings. The normal use as mentioned above would be a 200
meter zero. Using the Mauser sighting method, the front sight level with
the rear sight, would result in a zero of 330 – 350 meters. This is
about the maximum range practical for attempting to engage a target with
iron sights. I contend with the Carcano the Italians had a very
intelligent approach for a battle rifle. The fixed sights were basically
fool proof. The Italians must have realized with the M38 models that
nearly all small arms engagements occurred inside of 200 meters. The fixed
sights with a 200 meter zero would have been fool proof for a soldier
under stress, who was probably a poor judge of distance to begin with. The
soldier would have had to do nothing but point and shoot at the middle of
his enemy for ranges out to 220 – 230 meters. How much more simple and
effective could it have been made.

____________________________________________________________

6.5 x 52 mm

The Carcano rifles are capable of outstanding accuracy. With the exception
of a military issue type load in the short carbines they are very pleasant
to shoot from a recoil standpoint. Because of the above mentioned sight
picture for the Carcano, front sight in the bottom of the rear sight
notch, it is very important to have a consistent stock- cheek weld for
consistent accuracy. It is often very helpful to use a carbide lamp or a
sight black product to blacken the sights, which improves contrast and
sight picture.

____________________________________________________________

CONCLUSION:

The 6.5 X 52 is a very useful and capable cartridge. It served well as a
military cartridge for over 80 years. The 7.35 X 51 would have been an
even more effective military cartridge than the 6.5 X 52 had its timing
been different. It is interesting to note that the .308 Winchester / 7.62
X 51 mm NATO and the 7.35 X 51 mm are nearly the same dimensions. Both the
6.5 and 7.35 cartridges are fun to shoot and properly loaded capable of
very good accuracy. The Carcano rifle is a well made rifle that is by no
means weak or poorly manufactured. They are reliable and strong rifles
that are fun to shoot and offer a tremendous variety of types and markings
for the collector. I will admit that they are a rather utilitarian rifle
as compared to some others. However, they are probably one of the most
efficient, cost effective, user friendly battle rifles produced in their
era. The rifle, ammunition combination properly loaded is capable of
accuracy that will rival the most accurate of the Mauser chamberings.

Oswald's co-workers stated they broke for lunch at 11:50 that day of the assassination. Oswald stayed behind as they took the elevator down. Meaning Oswald had 40 minutes to re-assemble the rifle- from 11:50 to 12:30. With a screwdriver. Or a quarter. Oswald had that rifle since March 25 or about eight months before that day. Marina testified that she saw him practicing with it. Adrian Alba testified that he and Oswald talked a great deal about guns. In other words, Oswald was not a novice with that weapon.

I think anyone who believes Oswald was incapable of assembling that rifle or that he didn't have enough time is ignoring a great deal of evidence.

Three "perfect shots"? Wouldn't one "perfect" shot be enough? He missed with his first, missed - missed as in killing - with his second, and then about 8-9 seconds after the first hit the target on his third shot. He missed the first at nearly point blank range. Missed or deflected.

I think if you need to take three shots to kill a man you can't characterize the first two as "perfect shots." Unless he was trying to miss with the first two? In which case, never mind.

Oswald haunted pools halls, and the angled arm of the light standard cued him into trying to bounce a round and ding the womanizer. The second round was not heard by either party because they were busy either clearing their throat or being in shock, and the third round was meant as a warning shot but since Oswald didn't practice, practice, practice according to people who weren't anywhere to be seen, he hit nothing but the atmosphere instead of JFK's cheatin' heart..

Well, there seems to be an awful lot of evidence that the first shot struck JFK. The large body of consistent witness recollections of the 1.......2...3 shot spacing with the last two shots in rapid succession in itself is inconsistent with a first shot miss. And there are at least 22 witnesses who said it struck JFK.  There is no evidence at all to contradict the Connally's evidence that JBC was struck on the second shot   The second shot striking JBC is corroborated by several witnesses: Dave Powers, Gayle Newman, Wm. Greer, and George Hickey. We can see the damage of the third shot. So what evidence is there of a missed shot? Start with evidence that contradicts the evidence that the first shot struck JFK.

??

As far as the witnesses who provided corroboration that the second shot struck JBC in the back:


We don't need JBC to say that JFK reacted to the first shot.  There are 60+ witnesses, including Nellie, who provided evidence that JFK was struck by the first shot.  The question is whether JBC was struck in the back by the second. Both Nellie Connally and Governor Connally said that JBC was not hit in the back on the first shot. JBC said he felt the forceful impact of the bullet that struck him in the back well after he heard the first shot.   Nellie said she watched JFK reacting to his neck wound before the second shot that struck her husband. That is the primary evidence that JBC was hit on the second shot.

If Mr Andrew Mason is correct then 3 shots were fired in about 4.8 secs.

It matches well with Harold Norman’s (closest ear witness to the shooter ) boom clack clack spacing.

There has been suggestion made that the “clack clack” noise may be the “clink clink” noise of shells bouncing rather than manual bolt operation.

If so then a semi auto rifle such as an FN-FAL with larger scope centrally mounted , could have been the rifle used.

Such rifle seen by Arnold Rowland from distance when shooter was at SW window at 12;15 , could have been mistaken as an 30.06 hunting rifle much more probably than the MC rifle with scope mounted to side.

The FN-FALcould  be disassembled (barrel removed from receiver )such that both parts could be Possibly hidden  under a jacket . Or brought into the building in a 24” length package?

The shooter would need an accomplice to help use the East elevator to descend to the 2nd floor and exit out into storage room at approximately 45sec post shots

(Note: this possibly resolves the Mrs Garner by the 4th floor staircase and Adams and Styles descending staircase not seeing anyone on the staircase.)

Accomplice returns elevator to 5th floor and locks it there by 60sec post shots,

(Note: elevator travel speed approx 5 sec per floor based on WC testimony of approx 30 sec time to travel from
1st floor to 6th floor.)

The rifle could be temporarily hidden in the storage room or lunchroom just before Baker/Truly reach 2nd floor landing approx 85-90 sec post shots.

There has been suggestion made that the “clack clack” noise may be the “clink clink” noise of shells bouncing rather than manual bolt operation.

If so then a semi auto rifle such as an FN-FAL with larger scope centrally mounted , could have been the rifle used.

Such rifle seen by Arnold Rowland from distance when shooter was at SW window at 12;15 , could have been mistaken as an 30.06 hunting rifle much more probably than the MC rifle with scope mounted to side.

Norman heard a rifle being fired at the SE corner.

Quote
The FN.-FALcould  be disassembled (barrel removed from receiver )such that both parts could be Possibly hidden  under a jacket . Or brought into the building in a 24” length package?

The shooter would need an accomplice to help use the East elevator to descend to the 2nd floor and exit out into storage room at approximately 45sec post shots

(Note: this possibly resolves the Mrs Garner by the 4th floor staircase and Adams and Styles descending staircase not seeing anyone on the staircase.)

Accomplice returns elevator to 5th floor and locks it there by 60sec post shots,

(Note: elevator travel speed approx 5 sec per floor based on WC testimony of approx 30 sec time to travel from
1st floor to 6th floor.)

You're not allowing for the 10-15 seconds to open/close the gate door. Did the elevator instantly begin to travel or was there an initial lag?

Quote
The rifle could be temporarily hidden in the storage room or lunchroom just before Baker/Truly reach 2nd floor landing approx 85-90 sec post shots.

Who hid the 6.5 mm Carcano on the sixth floor? It would have a different caliber bullet that the 30.06 bullets fired by the "conspirators".

The questions about the why, when and how an MC rifle with useless scope was placed on the 6th floor, are I must admit, problematic to resolve as part of a CT theory.

As for the man with rifle at the SW window per Arnold Rowland, that’s at 12:15, then he is not seen again by Rowland. So this gunman moved to the SE window by not later than 12;24 so as to have time to put the box in the window before it’s recorded in the Bronson film approx 12:25.

So it’s probable that the black man that Rowland saw in the SE window at
12:15 was BRW who leaves that window by at least not later than about 12:23.

So a heory of a shooter with semi auto rifle at SW who is the same who moves to the SE window would be supported by Norman hearing only 3 shots from that SE window and not any other more distance noise  by a second shooter at the SW window.

If the operation of the East elevator gate and slowing elevator  adds 15 secs = 75 secs total time it’s still possible that TrulyBaker arriving at 70-75 sec to the elevators at ground floor would not perceive East elevator had been in operation a few seconds prior.

There might be a ? about if the cables were visible and If any lateral swaying occurs for a few seconds after and elevator cab has traveled 3 floors upwards.

There are problems with Rowlands' credibility and the "detail" he seemed to invent. Maybe Rowland thought more detail would increase believabilty in his stories.

(https://static.prisonpolicy.org/images/geographypunishment/w02_250.jpg)

Arnold Rowland was 250 or more feet away from the window he claimed he could see a figure's scar and "well-combed" dark hair. Also where were the "three women" on the Underpass he claimed he saw?

Quote
So this gunman moved to the SE window by not later than 12;24 so as to have time to put the box in the window before it’s recorded in the Bronson film approx 12:25.

Isn't Rowland scanning the upper floors at that time?

Quote
So it’s probable that the black man that Rowland saw in the SE window at
12:15 was BRW who leaves that window by at least not later than about 12:23.

Could be BRW in the set of windows next to the Sniper's Nest. Could be Dougherty at the SW window with a piece of board and not a rifle.

The same argument could be made for Brennan.

Quote
I noticed that his face seemed more square-set than angular, as it had appeared in the newspapers and on television. All of the people in the car were responding to the friendly crowd and waving. Kennedy was looking to his left towards those of us in Dealy Plaza. As the car came abreast of where I was sitting on the wall, Kennedy turned to wave at those on the other side of the street. The next moments have remained fresh in my mind for nearly twenty years. In one respect, the whole experience seemed to take only a few seconds. In another, it resembled slow-motion action that one sees in the movies at times. What has been recorded as taking less than ten seconds seemed like an eternity to me. I’m sure others on the scene felt the same as I. When the presidential car moved just a few feet past where I was sitting, President Kennedy looked back to our side of the street. Just at that moment the whole joy and good will of the day was shattered by the sound of a shot. It took an instant to realize that something had happened. My first instinct was to disbelieve my own ears. Nothing could have been further from my mind at that moment than that someone was trying to kill the President. My first thought was that it must have been a backfire. I’m sure many other people around me must have thought the same thing for there was no instantaneous reaction from the crowd. It was as if no one could really believe that such a thing was even possible, certainly not in Dallas.

I looked up then at the Texas Book Depository Building. What I saw made my “blood run cold.”

Poised in the corner window of the sixth floor was the same young man I had noticed several times before the motorcade arrived. There was one difference—this time he held a rifle in his hands, pointing toward the Presidential car. He steadied the rifle against the cornice and while he moved quickly, he didn’t seem to be in any kind of panic. All of this happened in the matter of a second or two. Then came the sickening sound of a second shot and I looked quickly back to the presidential car which had moved only a few feet, still not apparently aware that it was the assassin’s target.

I saw Governor John Connally reacting to being wounded and the instinctive response of his wife to try and help him. I remember thinking, “Oh my God! He’s going to kill them, he’s going to kill them all!” The immensity and horror of what I was witnessing almost overwhelmed me. I wanted to cry, I wanted to scream, but I couldn’t utter a sound. I could only watch the whole monstrous drama unfold.

Just then a woman close to me screamed in full realization of what was happening. She uttered something like, “Oh, my God!” But even as she did my eyes darted back to that solitary figure who was changing history. He was aiming again and I wanted to pray, to beg God to somehow make him miss his target. There wasn’t time to pray, not even time to think about what I was seeing but the sight became so fixed in my mind that I’ll never forget it for as long as I live. There was nothing I could do. It was a hopeless, sinking feeling. I would have gladly given my life in that moment to be able to save the President, but no one could move fast enough to shield him with his own body. Then another shot rang out.

All of this took only a few seconds. I didn’t realize at that moment that I was the only person who was actually watching the man firing the rifle. Simultaneous with the third shot, I swung my eyes back to the Presidential car which had moved on down to my left on Elm, and I saw a sight that made my whole being sink in despair. A spray of red came from around the President’s head. I knew the bullet had struck its intended target. Later, I would learn that the whole scene had taken less than ten seconds. In retrospect, it seemed like several minutes.

By the time the third shot had been fired, there was sheer pandemonium. Everyone was fully aware that the noise they were hearing was shots, not backfire. This was really happening. It was like a nightmare, only I couldn’t wake up from it. No one had to tell me what was ahead. The moment I saw the effects of the third shot, I knew that the assassin had been successful. No person could have survived that kind of wound.

Mass confusion and hysteria set in and I must admit, I was feeling it too. People were screaming. Men and women dressed in their fine suits and dresses, fell to the ground, getting them dirty, but hopefully getting out of the line of fire. At that moment, no one but me seemed to know where the shots had come from. By now uniformed policemen and plain clothes police, who I assumed were Secret Service or F.B.I. Agents came running from every direction. I jumped from the wall to try to get out of the line of fire. I never saw so many guns in my life. Most of the police were running towards the triple underpass which perhaps was a hundred feet or so ahead of the motorcade. Some were running towards an area to the right, slightly raised, which has come to be called the “Grassy Knoll.” Much speculation has been raised about whether there was another gunman there who was trying to catch the President in a cross-fire. Having witnessed the whole scene, I can say with certainty there was only one gunman present that day and all shots were fired from the sixth floor of the Texas School Book Depository. It is easy to understand why many thought the shots were coming from the area of the underpass as the buildings and open area combine to produce an “echo” effect.

Even as I hit the ground, my first instinct was to look back up to that man on the sixth floor. “Was he going to fire again?” I wondered. By now the motorcade was beginning to speed up and in only a couple of seconds the President’s car had disappeared under the triple underpass. To my amazement the man still stood there in the window! He didn’t appear to be rushed. There was no particular emotion visible on his face except for a slight smirk. It was a look of satisfaction, as if he had accomplished what he had set out to do. He seemed pleased that no one had realized where the shots were coming from. Then he did something that puzzled me. Very slowly and deliberately he set the rifle on its butt and just stayed there for a moment to savor what he had done, like a hunter who has “bagged his buck.” Then, with no sense of haste, he simply moved slowly away from the window until he disappeared from my line of vision.

If Mr Andrew Mason is correct then 3 shots were fired in about 4.8 secs.
Z195 to z313 = 118 frames = 6.4 seconds. The last two were 42 frames = 2.3 seconds apart so there was a tad more than 4 seconds - 76 frames - between the first and second.

If the WC photo exhibits are correct then the sight picture of the SE window shooter either thru his scope or via iron sights, is obstructed to some degree between Z186 to Z210

Is it being suggested that the shooter attempted to shoot thru the tree branches?

If so, was that a shot a hit or a miss?

If the 1st shot could plausibly be at z195 and is a hit to JFKs back and thru to Gov Connally   then should not Conally be already turned by impact of that billet when the limo emerges from
Behind the Sign approx Z222?

If Z 195 is a miss, and if there there’s a shot at Z223-4 that is causing a reaction of both men , would not that rule rule out an MC rifle since 195-223= 28 frames = 28/18.5 = approx 1.5 secs.?

That was a flawed conclusion from the flawed FBI re-enactment in May 1964.  Even their own photos showed that the full trunk and the JFK stand-in was visible at z207.

The better re-enactment done by the Secret Service in early December 1963 shows the tree as it was on November 22, assuming there was no growth in the previous two weeks or so.  It shows that the tree really never fully obstructed Oswald's view from the SN.  It also shows that JFK was visible when he was between the lamppost and Stemmons sign.
(http://www.dufourlaw.com/JFK/View_from_SN_after_tree.JPG)

That corresponds to between z190 and z200.

Quote

According to all the evidence, this was the first shot and JFK reacted immediately to it by moving left, clutching his chest/neck, assuming an expressionless face ie. not smiling and waving. So it was not a miss.

According to all the evidence, it did not hit Governor Connally in the back/right armpit.  The Connally's insisted that the Governor was hit in the back on the second shot.  The trajectory at z195 is right to left at an angle of at least 13 degrees. You can see this easily in the above photo. The bullet exited under and on the left side of JFK's tie knot. JFK's midline was not right of Connally's right armpit, let alone the 5-5.5 inches right that would be required.  Also the bullet condition of CE399 does not fit the wound characteristics of the wrist wound or the damage to the clothing (particularly the french cuff of JBC's right sleeve).

They are both reacting to the first shot, according to all the evidence.  JBC is reacting as he said: he recognized it as a  rifle shot, feared an assassination was underway and turned to his right rear to check on JFK. That is what he does from z230-z271 before he is hit in the right armpit as he is turned right.

Of course Mason uses the lowest-quality muddied version of the SS reenactment film, which makes it appears that head "blobs" can be readily seen and tracked through the foliage.

Nearly all of Mason's "expressionless face" witnesses couldn't see Kennedy's face. Most were "two-shot" witnesses who described the "first shot" where Kennedy slumped as the shot before the head shot. Mary Woodward and Phil Willis--who were near-to the limousine--said the Kennedys looked around after the first shot. We see Mrs. Kennedy, and the Connallys and Agent John Ready, turn to their right beginning in the Z160s or Z170s. This about where the little girl running in the Zapruder film, Rosemary Willis, begins to slow down in order to stop a few seconds later.

The Australian team in 2004 duplicated the "pristine" condition of a Carcano bullet going through two body masses, including a "radius" bone. Their bullet actually went through two "ribs" rather than one and emerged looking like CE-399.

Connally said he was facing forward, in the direction of the car, when he was struck. If his eyes were leading as he turned, and not staring fixed forward, by the Z220s, Connally would have looking forward, in the direction of the car. By Z227-228, his head is literally facing forward.

CTers repeatedly suggest that Oswald's scope was "useless" but how do they know that?  The rifle was placed behind some boxes after the assassination.  Maybe even dropped.  The scope was also removed to check for prints.  I don't believe there is any real basis to conclude that the scope was misaligned at the time Oswald pulled the trigger.  And even if it were, a shooter trained by the USMC to fire a rifle, who practiced with that rifle, could make an adjustment for any misalignment.   Just another CTer red herring to avoid accepting the obvious fact that Oswald used his MC rifle to assassinate JFK.

Beautiful work Jerry, especially the tree detail. Are the trees generated with fractals? Thanks for sharing.

The trees are a single component that was free online. I don't recall if it was an oak tree. I did some scaling to approximate the trees in DP. Some rotation for variation. Can't literally recreate the individual trees and bushes in DP as they were that day. It's more for cosmetics.

The "leaves" are a 2D photo texture that portray a few leaves separated by transparency. The texture needs a flat surface to be "painted" on, which are the squares seen in the monochrome "zoom view".

I had to modify the generic tree to simulate the branch blocking the view between the sniper's nest and roadway. Maybe a professional 3D team could take 1963-era photos of that tree and create an accurate model of the whole tree or the parts that block the view. But that's a lot of work and there has to be an interest on their part in the foliage-blocking issue.

There's more accuracy coming when the 3D professionals create a model using cloud-points. My model is just comparing the features in the model with photos and maps. I have a few aerial photos and a greatly-enlarged copy of the Myers map.

(https://images2.imgbox.com/e2/a5/WrOpVZls_o.jpg)

I find the color of the shrubbery odd. Along the walkway between the pergola and the corner of Elm/Houston, it seems purplish (inset pictures, lower-right). In the Zapruder film, the shrubbery in the background is orange-like. It could be two different plants or just the lighting.

For those unfamiliar with SketchUp, a "component" is an object that's imported as a "component", or made from scratch and grouped together as a "component" by yourself in SketchUp. The "component" sits in SketchUp's Component Tray. From the tray, you drag a component and situate it on your model. When you duplicate the component, you're not doubling the file size it needs (it gets that information from the "component" you made or imported). So making, say, one-hundred windows from a component doesn't increase your model's file size.

There's more accuracy coming when the 3D professionals create a model using cloud-points. My model is just comparing the features in the model with photos and maps. I have a few aerial photos and a greatly-enlarged copy of the Myers map.

(https://images2.imgbox.com/e2/a5/WrOpVZls_o.jpg)

I find the color of the shrubbery odd. Along the walkway between the pergola and the corner of Elm/Houston, it seems purplish (inset pictures, lower-right). In the Zapruder film, the shrubbery in the background is orange-like. It could be two different plants or just the lighting.

For those unfamiliar with SketchUp, a "component" is an object that's imported as a "component", or made from scratch and grouped together as a "component" by yourself in SketchUp. The "component" sits in SketchUp's Component Tray. From the tray, you drag a component and situate it on your model. When you duplicate the component, you're not doubling the file size it needs (it gets that information from the "component" you made or imported). So making, say, one-hundred windows from a component doesn't increase your model's file size.

I use a free program that is less sophisticated than SketchUp. But there are some similarities. Importing objects is something that I can do also. I learned how to use the program while creating the model. It has functioned as a decent tool for my purposes so far. But to make it look better, I probably should start over with SketchUp. The learning curve to become proficient with SketchUp is a major challenge for me due to too many other projects. But your work does inspire me to want to eventually go that route. Thanks for sharing!

I've been adding in some hedges and shrubbery to my 3D model. The road stripes are close to their placement on the Culter Plat and comparing them to Z-frames. My work is hobbyist. Professional 3D teams tend to work on the "big" issues, like the Backyard Photos, SBT and head shot, but smaller items like the foliage-blocking and autopsy photo orientation are also important.

The trees are a single component that was free online. I don't recall if it was an oak tree. I did some scaling to approximate the trees in DP. Some rotation for variation. Can't literally recreate the individual trees and bushes in DP as they were that day. It's more for cosmetics.

The "leaves" are a 2D photo texture that portray a few leaves separated by transparency. The texture needs a flat surface to be "painted" on, which are the squares seen in the monochrome "zoom view".

I had to modify the generic tree to simulate the branch blocking the view between the sniper's nest and roadway. Maybe a professional 3D team could take 1963-era photos of that tree and create an accurate model of the whole tree or the parts that block the view. But that's a lot of work and there has to be an interest on their part in the foliage-blocking issue.
Thanks for the details. That software is amazing, especially compared to the archaic text based modeling I’ve used since the last millennium. Someone, long ago, wrote a routine for fractal trees, but I could never get it to work very well for my Dealey Plaza model. Thus, my lollipop trees. I updated my Oak Tree using overlaying ellipsoids with a checker pattern using transparency. I compared your SN view to the Secret Service’s film, and am quite impressed with your tree. It probably takes a modeler to appreciate the amount of work that goes into even simple looking objects. I like the graphical design concept (like SketchUp) but this old dog gets too much enjoyment creating objects line by line.  I hope to see more of your plaza modeling. I have a lot of pictures and video (with time and date) and if you (or anyone else) would like a particular view please ask.

A photo I took two years ago shows both the pergola walkway and peristyle shrubs with purple color. Bronson's film of November 23 shows purple also, although the film seems to have some colorcast that possibly shifted the color to purple.

I found a 3D outer-flesh model and a 3D "High-Poly" skeleton model and merged them. The "Medium-Poly" and "Low-Poly" skeleton models changed the shape of some of the bones, so I used the best-quality model. This meant a large file size, so I removed some unnecessary bones. This does not affect where the bones in the upper body appear in the model.

I'm showing how many facets are involved in the "High-Poly" skeleton model and the articulation "handles" I added. Using the "handles", each articulation point can be rotated (to a reasonable degree; some joints don't rotate much) but the articulation points themselves remain attached to the articulation point of any neighboring bone it was originally attached to. For example, one can rotate the skull but it can't be detached from the C1 (or "Atlas") vertebrae. This preserves the integrity of the skeleton.

The scapula bone is very flexible and attached to the back by large muscles. The scapula has a connection to the outer tip of the clavicle. When the inner tip of the clavicle is rotated upward, the outer tip of the clavicle rises which in turn causes the scapula (and arm bones) to rise up. I think we see in the autopsy photos that the outer shoulders of Kennedy have risen up due to rigor mortis. The raised shoulder line is fairly flat in the photo, compared to life where the shoulder line tapers down from the neck.

On my model, the distance between the neck crease and the entry wound on the skin is 2 1/8" (or 5.5 cm as reported by the Clark Panel). By raising the scapula up, we end up with a similar distance from the scapular spine to the entry wound. Those two distances being similar is what is shown in the autopsy photo of the back wound. A resting scapula would not appear as high as that seen in the autopsy photo.

I notice that young Kennedy's right clavicle protrudes from the body more so than the left. I think I see something similar in the autopsy photo, which helps to authenticate the photo.

Nice work Jerry!  I believe that having his right arm raised so that it rests on the side of the limousine would raise his clavicle, etc. But it appears that there is ample space between the path of the bullet and the clavicle for that to occur without the bullet striking the clavicle, etc.

Ever notice how the West and East slabs of the Triple Underpass Bridge differ in height?

(https://images2.imgbox.com/c0/c0/lz7Zy6EP_o.jpg)

A source tells me the streets slope downwards east-to-west inside the tunnel. I'm using a 1° slope in my model. I will have to merge this somehow with the 3° slope of the streets that run through the Plaza.

That's what works in my model. Might not work in yours.

Very interesting. I never noticed that before. I'm hoping for a DP trip later this year and would be able to take any measurements and photos you think would be helpful. Start a list and I will attempt to do what one crazy guy with a laser measure can safely manage.

Thank you, James. I'll post measurement requests in graphic form here. With all the bevels, and slanted and rounded edges on the bridge, verbal description would not be accurate. Please do what measurements are safely possible. I understand some measurements may not be possible if the sun interferes with the laser. Whatever you can provide will very much help.

I'm including some of my empirical measurements so we can later see how far off I was. :D

Thanks for the schematics. Just a couple quick comments.
1. Hate to whine, but I will like a working copy on a clipboard, but my printer is B&W. There is very little contrast with TUP, arrows and background. Can you change the text and arrows to white with a global command?
2. I was planning to laser measure, from street level east side column heights from street curb to top in the afternoon and west side in the morning for shade. The laser will  help topside, but there will be much tape measuring.
Looking forward to doing this! I have done several measurements here and have a feel for what is in store.

Just got home and unpacking stuff, and brain. I'm pretty happy about the results. I think the only measurement not (safely) made was the 90deg distance of the overpass, basically due to the freeways to the west being too close to line of site. Some longer distances are composed of smaller segments. Your revised drawing helped a lot with documenting measurements without having to try to describe them while measuring. More later in a day to two.

Closeup of a typical edge bevel. I used 1” for my measurements but 1.25” might be closer, based on this image. I’d like to note that the bevels are everywhere! The devil is in the bevels for making close measurements as there are almost no sharp edges to be found. Were the edges originally sharp but eroded over 85 years?

Thanks James for such useful data. Now I can zoom in on my errors.

Some measurements I was surprisingly close to. I was off quite a bit on pedestal heights and some 200% in error on the thickness (east-to-west) of the banister. These are errors from my looking at photographs rather than measuring (which is a huge task to ask of somebody).

With the laser I measured the heights above curb of the second column from the north (south side of sidewalk) on both the east and west sides. The height for the east column is 24’ 5” while the west column is 23’1”.  The difference of 16” over 124’ gives an average slope of -0.58 degrees in the westward direction.

I have a level app on my smartphone, but unfortunately only measures slopes as whole numbers without decimal precision. Readings for the eastern half were 1 degree and for the western half 0 degrees, for an average of -0.5 degree for the length of the underpass. Readings of the sidewalk approaching the underpass showed as 3 degrees.

Photos of the support columns from the inside shows a change of slope near the midpoint of the underpass.

Slope inflection. Never would have guessed. The roadway emerges on the west side of the bridge level. Makes sense now you've discovered it.

Was trying to come up with a motorcycle model for the Harleys in the motorcade. The cycles in the insets above have a fuel tank emblem unique to 1961 and 1962 Duo-Glide models.

(https://nationalmcmuseum.org/wp-content/uploads/2020/02/1958-harley-davidson-duo-glide_25.jpg)  (https://cdn1.mecum.com/auctions/lv0120/lv0120-392754/images/lv20-r356-11-1574460185058@2x.jpg)

The insignia on the "bubble bags ("saddlebags") may be a clue as to whether they are 1961 or 1962. However, I have seen "Arrowhead" and "Rocket" decals (like on the DPD cycles) in models from the late-50s to the mid-60s. I have seen the "Arrowhead" in ads for the 1961 Duo-Glide.

The 1962 model saw the introduction of the "tombstone" speedometer.

(https://cdn1.mecum.com/auctions/lv0122/lv0122-488981/images/-15-1631301228320@2x.jpg)  (https://www.shannons.com.au/library/images/auctions/MA2VCK3D1551R2C0/KB6DAS57WSL9F85H/1600x1066/1960-harley-davidson-fl-duo-glide-motorcycle.jpg)
Left: 1961; right: 1962. Note: the Day-Glo Green number color was an unusual option.

Side note: Harley-Davidson did a lot of work with their "Police Special" accessories. They seem to have outfitted entire fleets, probably at a group rate. One option was the police speedometer. This was before police radar, so a policeman on a motorcycle would follow behind a speeding motorist and when he got to the same rate of speed, he could press a button that would lock the needle on his speedometer. He could then show this to the motorist and use it as proof in court.

Hubcaps on the limousine in 1963 were the large "sombrero"-style hubcaps from the 1957 Lincoln Premiere. Stock Continental hubcaps wouldn't fit the bigger tires used because of the limousine's weight.

Thanks for providing this comparison.  The question is: which one should we use?

In comparing the three cars, it appears the Hum3D model has a longer wheel base than both yours and the Ford Licensed.  There are major differences in door locations and compartment widths between the three models.

One thing that is odd, is the width of the glass and the middle space as shown in the Ford model.  I note that there appears to have been an earlier version of the side window and roof support as seen here:

Following up on my last post, it looks like the HUM3D model is accurate when comparing it to a side view of the limo when built at Hess Eisenhardt:

Until a few weeks ago, I had the door seams located a few inches toward the back. I moved them forward to match the full-length photo of the limousine in use. Maybe the outdoors limousine photo was retouched. Or maybe a pincushion effect is in the photo that's not in SketchUp. Strange. The wheelbase amount shown is how it appears right in the model.

Hubcaps on the limousine in 1963 were the large "sombrero"-style hubcaps from the 1957 Lincoln Premiere. Stock Continental hubcaps wouldn't fit the bigger tires used because of the limousine's weight.

Nice work Jerry, it's interesting that LNers understand geometry and perspective and think in 3D and then use this knowledge to solve problems whereas CT's just guess and embarrass themselves.

I checked out the Hum3D model and it seems pretty good in most areas.

The overall length of the limousine from the WC/HSCA was at-or-near 255" (42.6" longer than a stock 1961 Continental). On this model, it's 248" (35.6" longer than a stock 1961 Continental). The light projections on the front bumper would add another 2 1/2" to the model's length (making it 250.5"). But we don't know what two points on the car were measured in 1963/64 or if the official figure was measured on an horizontal.

There's a researcher named Roy L. Schaeffer who claims the limousine is 248" long. I think the foremost point of the front bumper and the rearmost point on the rear bumper are obvious places to measure between (as I have done with the model).

The wheel rims are supposed to be 15" wide but the model shows 17" (the Hess & Eisenhardt profile photo supports the smaller rim diameter; maybe the rim in the model was one used after the "Quick Fix" alterations and is currently on the limousine on display at the Henry Ford). The rubber tire reportedly was 27", so 26.5" on the model is very good.

The rear door on the model measures about 40" long on the outside. The door seam tapers at the rear top of the door, so the door length reduces to 38" for the inside. The glass opening in the partition on the model being 9 1/2" wide seems correct. The curvature of the parade bar feels off; the bar doesn't exist in the limousine on display as the car was given a permanent roof. If the limousine on display was scanned, they would have to approximate from photos the parade bar.

The door handles and the chrome script reading "Continental" were reported eight inches long each. I have added onto the rear deck some figures from the WH/HSCA diagram.

Most impressive is the approximately 78.6" limousine width, the published width for a stock 1961 Continental. We don't know what two points were used to obtained the width (door handles and the projections along the wheel wheels are a bit outside the car's "slab sides". On this model, there's a very close correlation of the official car width with the width on the model between the "slab sides".

I would feel more confident about this model if the overall length issue (255" vs. 248") was resolved.

Thanks, John and Charles.

I think we have a winner with the Hum3D model. Unless you have day-to-day measuring access to the limousine, scoring some 80% alignment and near-alignment is pretty good.

If one is competent in their photo-matching, then a few tweaks of the Hum3D model would settle things. In this case, the back seat area of the model would have be moved back a bit, some door seams and the parade bar nudged forward a bit, the front tire and wheel well shifted back a small amount, and so forth. Not a big deal except the facet-count of the Hum3D model is astronomical and I can't do any reconstruction on my set-up. I'll have to instead adjust my old SketchUp model to match the new information.

(https://images2.imgbox.com/b2/29/ihrkStO1_o.jpg)

On the other hand, my photo-matching could be really off and someone better at it could match up everything between the model and the factory photo! Incidentally, I had to adjust the vertical-scale of the factory-photo that was from the Henry Ford Museum. That's another thing that could be throwing matches off; early scanners sometimes were off with aspect ratio.

I think I see what you are referring to Jerry. I think that some if the effect may be due to the angle. Example, the pillar at the far right appears to me to project out further than the one in the middle. Also, the fancy facade of the section of the bridge over the walkway doesn’t exist in the sections of the bridge over the roadway.

I was using these images to improve my 3D model of the overpass by overlay of the renderings. As typical for me, I put the project aside for another and have not finished that work.
The images were taken during my “Storm Drain Panoramas” project and include the overpass under sun conditions showing useful shadows. I find that method fairly sensitive. If you can view your model with these parameters you might find the time stamped images useful.

Hi, James,

(https://images2.imgbox.com/8f/13/K7CUxJvG_o.jpg)

I used one of your images to show the subtle curvature at the bottom of the three traffic spans. I think the "arch" effect is mainly due to the raised steps at each end of the spans. I would say the central portion of the bottom edge of the spans are level.

Thank you for pointing out the shadows. The twined-pillars of the pedestrian walkway cast a smaller shadow onto the superstructure facing of the bridge ...

(https://livingnewdeal.org/wp-content/uploads/2014/09/Triple_underpass_dallas_2014-1000x666.jpg)

That adds to my suspicion that the twined-pillars are a little closer to the superstructure facing than the two single pillars.

Here are two more images. One shows the arching steps from the south tunnel and the second shows the south column profile from the north tunnel-showing the column is recessed from the roadway column. I think I have dimensions for the pedestal so we can estimate the offset of the two columns. I will look later today. Jerry, I’m curious, can your software create a file for 3D printing?

I think I have dimensions for the pedestal so we can estimate the offset of the two columns. I will look later today. Jerry, I’m curious, can your software create a file for 3D printing?

It can in an indirect way using the most basic file format for 3D printing. I use the SketchUp 2017 application, and can export .STL and .DAE (Collada) files, in addition to SketchUp. I haven't tried anything with 3D printing but, through Googling, have some information.

1) The SketchUp model must be a solid. So I will make a copy of the Underpass model and on that copy, I will collapse the groups so the model are one entity (or alternatively divided into several entities that each are one group) with all the faces oriented the same way and "leaks" corrected. Because my models are made from scratch and not from intensive on-site scanning that usually over-samples, the facet-count is low, so the file size will be small.

2) The best straight-forward format is .STL.

(https://images2.imgbox.com/f8/22/61Qhrdo5_o.jpg)

I did a sample using the walkway arch. I don't know if it's the complexity or my inexperience, but it became a six-hour project. The "leaks" can be a minute amount apart and not readily visible (the Solid Inspector will highlight in red the general area affected). I kept at it until I succeeded.

Alternatively, I could create .STL files as is (with no "errors" corrected) so others could correct them using more-modern software. Those exports won't be for while, when the model is at a reasonably-accurate stage.

Now I'm using 2017 software (including the version of "Solid Inspector 2"). It may be that a modern 3D printer could itself have software that corrects the minute "leaks"?

Very impressive, thank you for this info. I think if I was 20 years younger I’d be all over this. But I do have a very talented and generous cousin making 3D trinkets, puzzles etc. as gifts. He does not do any computer design or editing, but probably would enjoy such a 3D printing challenge. I don’t know any of his equipment’s requirements or capabilities but would expect the exploded parts scheme would be used.  I asked him jokingly to print for me a 3D printer for our last family reunion. Sure enough, he did. It is all in parts, that need 20 or so very tiny screws to assemble it. Of course it is for display only and not functional. I suppose there are 3D printing services readily available, but keep in mind when you are satisfied with your model.

I’ve updated my 3D model for the TUP’s bridge and tunnel columns for comparison of their shadow length along the base of the underpass (green in the simulation). For reference I modeled the scene to overlap a photo from the west that I took last year 220927_125830 (with known sun azimuth and altitude).  I then replaced the north column of the south tunnel (right side of frame) and incrementally decreased its separation from the bridge until the the shadow overlapped the reference frame. This overlap came at a 11-12” decreased separation.  I also did the same modeling for an image taken from the south Elm storm drain. However, that image was taken from a camera generated 360 panorama that stitched many frames, without regard of quantitative analysis. Nevertheless, modeling gave a similar estimation to the first result of about 12” recession compared with the bridge columns.

For the bridge and tunnel column profiles I used an image I took in 2019 looking north from the south tunnel (guesstimate midway between the two tunnel columns). The camera image has a field of view of 65.5 degrees. With help of Google Earth to estimate distances I calculated the dimensions shown in the image. I did this for each of two photos taken with slight shift for stereo and am showing the results from each photo. A crude approach, but actual measurements with a measuring rule were little more than SWAG anyway.

Thank you, James. This is good information I'll incorporate into my model.

A while ago, you posted about the heights of the bridge columns ( Link (https://www.jfkassassinationforum.com/index.php?action=post;quote=139988;topic=3127.48;last_msg=149214) ).

    "With the laser I measured the heights above curb of the second
     column from the north (south side of sidewalk) on both the east
     and west sides. The height for the east column is 24’ 5” while the
     west column is 23’1”.  The difference of 16” over 124’ gives an
     average slope of -0.58 degrees in the westward direction."

One source said that not including the railing aspect of the Triple underpass, the [road into the] Underpass is 24 ft lower than the level of Houston street. I understand you measured the two columns from the top of the sidewalks but where to the top? That is, it would seem 24' 5" is not to the very top of the pillars but maybe to the bridge roadbed or the top of the railing?

The eastside pillars being 24' 5" in height (from sidewalk surface to very top of pillar) means the top of the pillars are level or nearly-level with Houston Street. I think we see something like that in the photo on the right.

Therefore, the traffic roadbed that enters the bridge tunnels on the east are roughly 24' below Houston. The Commission used the rounded figure 24'. I was under the false impression that the flat surface (on which trains run) of the bridge was level with Houston. It is actually several feet below Houston.

Must be a slight downhill grade between the Depository and the rail-bridge. I believe I can make it work now. Thanks.

My apology for the confusion. My goal was to measure bottom to top of the columns. This turned out to be more difficult than I anticipated. What I should’ve written is “I measured the heights above the pedestal tops…” for the tunnel columns. Columns W1, W2 and W3 are numbered from the north increasing southward. The same for the east columns E1, E2 and E3. I began the measuring project with bridge column E3, which does extend down to the curb. The same with W3. I then began measurements of the tunnel columns W1 and W2. But for the tunnel columns I was not able to get direct (single) measurement from the top to curb, so decided on using the pedestal top as a base. My thinking then was to know the pedestal heights and add the two measurements. But the tunnel pedestals don’t reach the curb as they sit on blocks above the curb. It appears I did not make measurements of those blocks. Therefore, I can only provide column top to pedestal top lengths for tunnel columns. Here are data for each column. Precision or accuracy is not impressive.
Uh, would all of the pillar pedestal tops be at the same elevation?

   Column Top to Pedestal Top
W1   21’4” (seems low, perhaps I measured the middle ‘step’ instead of the top)
W2   23’1”
E1   22’7”
E2   22’10”

   Column Top to Curb
W3   30’0”, 28’6” (Elm traffic interfered with measurements, so no attempt to keep trying)
E3   27’3”, 27’7”

Very helpful.  On my 3D Sketchup model of DP I get 490 feet from the bottom SE corner of the TSBD to the middle of Elm at the entrance to the underpass. So the average slope is arcsin(26/490)=3.04 degrees.

The rubber tyre diameters don't match. My model shows tyres with a 27" diameter.  It may be that the rubber tyres are bigger. Need more information.

In 1963, the limousine received a set of "sunburst" wheel covers made for the 1957 Lincoln Premiere, that measure 15" across. The same diameter as the hubcaps in the SketchUp model. So at least the wheel covers are accurate.

The original stockade was built of logs, placed side-by-side vertically to form a defensive wall. The 1963 decorative "stockade fence" was made of planks with machined curvature on one face. The 1980s version that's up for auction seems like small irregular logs sawed in half vertically. Evidently they were looking to evoke the "Old West" look.

No one builds traditional stockades anymore, so the term "stockade fence" now mainly refers to decorative or privacy fencing. Such a fence needs only a pointed top to be "stockade"-style and doesn't have to be curved on its front face. Such fences are usually sold in sections. The 1963 fence might be made of same-length sections that are attached to evenly-spaced metal posts.

    I thought this "STOCKade" fence carried that name in reference to "liveSTOCK" being confined in this same area at one time. This made it convenient to then load the livestock onto the trains for transport. I don't know how secure anyone would feel with a fence such as this serving as a "defensive wall", even if it were made of logs. It is only roughly 5 feet tall.

They're using the "low" entry point for Kennedy's back wound. Since they're not showing a jacket bunch, I guess they went about four-inches below the top of the jacket collar. Photos show the top of the jacket collar was tight to Kennedy's nape and went to the hairline

Connally was sitting upright (if not a little backward) in the early-Z220s while they have the Governor's torso leaning forward.
They also have the bullet hitting JFK in the centerline, and it looks like they have the shot coming from the western pane of the first window, rather than the eastern one. And there's nothing to account for the uncertainty of the measurement of the actual wound locations. If this is all these guys have, they're either amateurs, lazy, or just incompetent.

Like the official investigations and NOVA/Frontline shows, this study is a good-faith analysis by experts in their field. Technically, it's the most extensive 3D project to date. The road looks kind of crude, so I wonder if they ran out of time. Don't know if any programs are going to use it.

They may well be working in good faith. But that doesn't mitigate the incorrect entry location or the incorrect rifle location. And the lack of any accounting for uncertainty betrays a fundamental lack of rigor. The only noteworthy thing I see in the Knott Labs animation is that they used one o' them newfangled 360 degree laser-based automated area surveyor devices to map Dealey Plaza.

Maybe we're just looking at an unfinished product, but the presentation so far is underwhelming.

There's an auction closing today for a fence section owned by Larry Howard. Link (https://www.rrauction.com/auctions/lot-detail/li/348117206780110/cat/0/SortOrder/hp)

You are totally correct, Jerry.  The fence section Howard had was not original.  It's one of the many replacement sections added to the frame of the fence since 1963. 

I believe this is not the 1963 fence because the fence Holland and Lane stood behind in 1966 had a different taper. I believe the 1963 fence had no gaps between the pickets and that there was a curvature on the front surface of each picket, in order to simulate a "stockade fence".

    Thanks John. Now if you just stand JFK on his head, you can get a bullet fired Downward from the 6th floor to exit the throat as diagrammed. Those 7 Living Parkland Hospital Dr's on Paramount+ will inform at least 2 generations as to the  BS: that has thus far been foisted on the public regarding this issue. And when they also learn about Gerald Ford's clandestine relocation of the back wound, then it's Posner Time. "Case Closed".

The museum has the sniper window about 5 inches lower than the Dillard position. I seriously doubt the museum would have moved if for the 3D scan. And, I don’t have any idea if that would be an issue with the trajectory analysis.

    With regard to the sniper rifle "trajectory", Max Holland claims that Oswald was STANDING when he fired Shot #1, and then either sat or knelt when firing shots #2 & #3.  This "Slinky Man" M.O. would definitely impact the calculation of possible rifle trajectories.

The pic you've posted is from z225.
JBC is shot through by z225. His rib has already been crushed. His body has already begun to rotate from the mechanical impact of the bullet crushing his rib. The debris from the shot exiting his chest has caused his jacket to bulge forward.
How can this provide an accurate trajectory for the bullet passing through JBC?

Lamp post in the Knott Z225 frame is from this year's cloudpoint-scanning. I think they should have removed the modern-day lamp post and put in the 1963 tree. Seems like they ran out of time. The project was commissioned by a conspiracy loon; the 3D modelers of the major physical features in Dealey Plaza were accurate. The subjective add-ins (the limo and wounding positions, the JFK inshoot) are what's problematic.

    This is exactly why they continue moving/removing Land Marks inside Dealey Plaza. It is difficult to position articles/people when land marks have been moved/removed. And this shuffling of Dealey Plaza also impacts any possible Acoustic Testing. For now, the Knott Lab findings rule the day.  SBT = IMPOSSIBLE

There’s only one orientation for Connalys body that can align the single bullet trajectory and that is to have both of  Connallys legs rotated clockwise to some degree approaching 45 degrees to match his upper torso and shoulders which appear (imo) in Z223-225 turned ( along with his head) to be turned towards the right side of the limo .

The best approximation diagram I’ve seen for Connally holding his hat is that it was held upside down with the well of the hat hanging off the left Side of his left leg , being held with his right hand using his palm to press the rim of the hat against the top of his left leg.

This orientation is about the only one that allows the bullet passing  thru the top of Connalys wrist bone then into his thigh, without having to pass thru the hat or cause bloodsplatter on the hat..

I think having Connally's legs as far to the right (the right leg against the car door) is correct. If his leg were jammed right, then he couldn't get "push" to turn around to see JFK as they approached the sign. As well, the Governor's legs being far to the right meant he was "primed" to fall back towards Nellie once his upper body turned far to the right. This kind of stuff would be great tested on live models in a similar confined space.

3D models generally come orientated to the X-Y axis and have none of the off-axis fluidity of the human body. I can make my 3D models go off-axis but a live model would be needed for a guide. Otherwise it's guess-work.

Sorry Royell, but you really don't know how any of this works, Hulk Connally by definition is sitting in a guessed position.

Just because Knott Lab's cartoons have been used in court doesn't mean that their finding are beyond reproach or can't be challenged by better corrected evidence because that is how your court system works.

Btw I asked you before, when did Knott Labs scan JFK's Limo, it's position on Elm and it's occupants in their precise position or did they rely on guessing all the above from a fuzzy Zapruder frame? Which as you well remember, you claim this source is fake or are you going to backflip once again?

The youtube video is interesting but appears flawed. It looks like they have made a number of false assumptions, and the end result is wrong. In addition to what John has pointed out, the shot did not take place at Z225, it took place at Z218 or earlier. It looks like they positioned LHO in the center of the double window not at all close to the east wall side. They are 1 to 2 feet off from where he was actually located. The first shot most likely took place with the rifle retracted into the room to avoid detection from the street below. He was likely located nearer the edge of the window by the East wall. Correcting these errors, I believe that would move JBC back to where he was actually sitting.

Unless there's been a clearer view posted, I think the firing origin in the center of the window may be an illusion, caused by the line-of-sight given and the "clever" use of too much transparency.

You need at least one of the two figures (JFK, JBC) visible to see his position, plus you'll get more of the limousine. I believe the SBT was earlier than Z223 (which is clearer than Z222), but would their positions have changed that much in two or three frames? If they did then no one can do a 3D study ever since we can't see through the sign.

Hahaha.

Which stills and images? You're on record telling the entire World that the JFKA image record is unreliable. Hilarious.

Something is definitely Not Right with the Altgens photo.  JFK Assassination Photos & Films which are engulfed by Un-Explainable/Contrasting/or Missing Images are in abundance throughout this case.

Which stills and images? Because here again you are on record claiming any attempt to match-up images is futile, unless of course the images were being matched up by Knott Lab!? Laughable.

         Attempting to get ALL the JFK Assassination Images to match-up is futile. Doing so results in Chasing Your Tail which is a Mission Accomplished by those responsible for the image alteration we continue to see. There are JFK Assassination Images which are legit, and some are Bogus.   

And we know from their video that Knott lab used the Zapruder film "still" as the cornerstone of their match-up.

...corroborate the Current Z Film NOT depicting reality on 11/22/63.
 
Even though you inadvertently have supplied further Proof of the Current Z Film being Bogus,

The Blackest Hole in the Z Film, (and there are many),

   The Lead Runner is visible on the Z Film for only scant seconds. This Lead Runner is Not visible on Any other JFK Assassination Film or Any other JFK Assassination Image period. This gent would have been in front of the man we see on the Bell Film running toward Houston St.

   Possible "removed frames" does Not explain NO ONE at Parkland Hospital seeing the Massive Hole/Flap in the (R) Temple area. The ONLY Explanation for Not 1 Single Dr or 1 Single Nurse seeing the Massive Wound and/or blood trickling from it onto the hair of JFK is that the Wound DID NOT EXIST!

The Z Film is Not a portrait of Officer Chaney. It captured peripheral images vs that which researchers over the last 54+ years have foolishly & repeatedly Focused on.

My thought is the CIA had prepared a Z Film alteration

And this is only a small sample of the drivel about film/photo alteration you have been posting over the years, so this new found faith in Knott Labs reliance on the "still frames and photographs taken on 11/22/63" not only rings hollow but shows that you are truly the worst type of Troll.

  Ah yes, another member of the Dennis Hopper aka "Shooter" club staggers into the discussion. Waving his arms, and incoherently raging because The Science they claimed proved a LN was responsible for the assassination of JFK, has suddenly turned around and bit them in the arse. As The Science continues PROVING CONSPIRACY, comfort yourself in knowing that, "The TRUTH will set you free". LN's have been duped for 60 yrs. That's tough to accept, but for the sake of you and those around you, you need to stop the arm waving, curb your rage, and actually research Knott Lab Laser 360 Technology and how the US Justice System routinely uses this SCIENCE.   

Ironically if Knott Labs SBF work ever got to a court, I'd use Royell Storing's very own words to discredit it! High five!

    You LN's are so stunned, you Fail to understand that Knott Labs was SOLELY FOCUSED on the SBT/Magic Bullet Trajectory and that this was ONLY STEP 1. Pull yourself together and actually research what Science is still revealing. You have been "played" for 60 yrs running.

Ok I’m not really sure how accurately their computer model orientation of Connalys shoulder angle matches what my eyeballs are seeing in the Z film at Z223-225 so I’m not going to be an absolutist just yet.

But if it’s not the Z223 bullet that went they Connalys wrist BEFORE he raised his right got hand griping the hat still upside down , then WHEN does a spombleprofglidnoctobuns hit his wrist and yet not splatter any blood on the hat?

Wouldn't the shirt and jacket contain the majority of the blood splatter from the chest exit? The exit wound on the wrist was not large; it had to be surgically enlarged to be cleaned. The Stetson didn't pick up much blood from the blood splatter of Kennedy's head wound. I guess the hat was just in areas that received little splatter.

@Jerry: I’m generally in agreement with LNs about the Z223 SBT because of the simultaneous movement of JFK and JC.

I just disagree that the bullet was CE 399. Imo it was a more pointed shaped bullet unlike the ball
shaped  6.5 mm MC bullet.

My point about JCs right hand is that there is really  no way he could have been hit in the wrist of his right hand after Z225 because he’s then holding up his right hand with the hat being gripped tightly.

At the point with way his hand is up gripping the hat, there’s a high probability there would not only be some blood splatter from the bullet exiting his palm, but there would be a HOLE in the hat !

So because there’s no hole and there’s no blood found on the hat ( at least not visible) then it seems to me that it’s no choice here for a CT but to accept the most probable way that wrist wound occurred was while the hat was being held over the JCs left leg which imo was rotated approx 45 degrees clockwise ( towards right side door ) so that JC wouldn’t have his knees jammed in the back of Kellerman.

The exit wound was a slit, by Gregory's account. That's not uncommon for low energy projectiles.

I wonder exactly how much blood would be expected to be ejected from such a wound, and how much would need to land on the hat before it became noticeable in the Z film?

More zingers. You think there's no guesswork in the Knott Laboratory study's subjectively-placed elements? Where have you addressed the concerns raised here about the Knott study/

There's a margin-of-error in any trajectory study. Somehow the critics think that LN-produced models and trajectory have to match on the molecular-level. That gives them their "out" to reject anything SBT-related. It's a cult.

Maybe give them an attaboy for effort but it looks to be little better than a circus trick. Thomas Canning and old school math is infinitely better. A survey transit and basic trigonometry with explanations of all the assumptions and measurements is easily followed and understood. This 3D model looks to be anybody’s guess and in conclusion here is the end result. Nothing more than one more individual trying to prove it is a conspiracy using faulty logic and poor reasoning.

Thomas Canning had an oval shaped possibility around the window as to the origination of the shot. It was all based on an intricate set of measurements and assumptions. The Circus Trick 3D model appears to originate the shot out of the middle of Canning's oval. They in their infinite wisdom pinpointed something that cannot be pinpointed and then they and you have now labeled it as science.

Sorry to interrupt this verbal diarrhoea Royell, the Warren Commission never relied on the SBF. Oops

There is very persuasive evidence from the experts to indicate that the same bullet which pierced the President’s throat also caused Governor Connally’s wounds. However, Governor Connally’s testimony and certain other factors have given rise to some difference of opinion as to this probability, but there is no question in the mind of any member of the Commission that all the shots which caused the President’s and Governor Connally’s wounds were fired from the sixth-floor window of the Texas School Book Depository

Have you seen that photo of the mock JFK Limo back seat with a couple of guys sitting there as stand-ins for JFK/Connally, and Specter holding a Pointer to replicate the trajectory of the SBT as it traveled through both men? Now, THIS is truly "cartoon" worthy. Yet, this is what you embrace. No SCIENCE there. NONE. Though it is definitely 3 Stooges worthy.

Good of you to point out this, but the fact is that they offered no alternate explanation.  In particular, they never discussed where the shot through JFK's neck went if it did not strike JBC in the back. [They also never thought to question the assumption that JBC had been hit by only one bullet.]

The conclusion of at least one member, John McCloy (and perhaps the other three that accepted the SBT) was that JBC was hit in the back by the first shot and did not notice it (despite his clear recollection that he felt the impact immediately and knew he had been hit).  This was the controversial aspect of the SBT for 15 years until the HSCA came out and suggested that the first shot missed.

The SBT has had a long evolution. And it still keeps changing.  I have always accepted the WC conclusion that Oswald fired all the shots. But I disagree with the SBT.  I disagree only because of the large bodies of consistent evidence that conflicts with it.  The evidence shows that no missed shot and is consistent with the overwhelming evidence that all the shots came from Oswald's rifle.

Seriously @Andrew Mason: ARE YOU OK ?
Because suggesting that JC was hit in the back by the FIRST shot!?? Which you suggest was fired at Z195? ( when Willis girl stops running), is like REALLY pushing the plausibility meter far into the red zone imo :)

And if JC were hit at Z195, the forward motion of his right shoulder would not be starting at Z224-225, but would have occurred at the moment of impact at Z195-96 thus at Z223 his right shoulder would already be turned and he would have already probably my be clutching his hat and raising it up.

I’m not adverse entirely to trying to work out that a 1st shot was fired thru the tree foliage because Maybe the 6th floor shooter whether Oswald or some one else, had some experience at shooting thru foliage ( like a Vietnam sniper for example) thus it’s not necessarily implausible to have shot thru the tree foliage.

However, imo,your theory would work better if the 1st shot was at. Approx Z 170 so that there’s not only the required 2.3 secs to fire again the MC rifle at Z224, but the angle for Z170 shot makes it higher probability to bypass JFKs right shoulder.
