The Myers  computer graphics model somehow aligns the SBT trajectory. It looks good in that computer simulated reality, however in the real world of physics experiments the trajectory did not work out so well since no experiment so far has been able to replicate the bullet exiting the throat. They got it almost there in the 2003 experiment with the 2 torso models demonstrating the 6.5mm bullet fired from the MC rifle could go thru 2 bodies. However the straight line trajectory is clearly well below the throat wound location.

The experiment left  off the arms and hands and heads and the torsos were fixed and stationary. Thus experiment was doomed from the start to be an inaccurate representation, probably because they did. not wish to address the wrist wound problem and where exactly JCs right hand was positioned at Z224.

You give no specifics on how the straight line trajectory was determined so why should we assume this experiment was more accurate than what Dale Myers did.

The best evidence of the SBT trajectory is what did happen on 11/22/1963. We know the bullet that entered JFK's back exited his throat. It is hard to believe that the bullet would not have struck JBC somewhere on his back. If the experiment you reference indicates the bullet would have hit JBC lower than it did, than obviously, the experiment was faulty.

In order for any recreation to refute the SBT, it would need to show how the bullet that exited from JFK's throat could have missed JBC and if it did, what it would have hit. Any experiment or recreation that shows the bullet would have hit JBC somewhere other than where it did has disproved itself, not the SBT.

JFK Assassination Discussion & Debate / Re: The First Shot
« Last post by John Corbett on Today at 03:43:18 PM »
"Herb Huskr" posted this on 22 August 2024 at the JFK Truth Be Told FB page:


There is some active discussion on another forum where I’m not a member about James Tague being hit, a curb mark, and what happened there. This post is about some modeling and simulation results made awhile back evaluating a possibility to explain that Tague incident.

I’ve not routinely discussed these details before because there is a back story that suggests that the modeling indicated how wrong I may have been with my initial gut feeling, and who wants to embarrass themselves by admitting they may have been misled by an erroneous gut-feeling bias?

The modeling was done a few of years back to try and prove this initial assumption:

A missing fragment from the z313 head shot could not have made it to Tague and created a shallow curb divot sending mortar/sand shards up and out, with some striking Tague in the cheek while he was standing nearby.

The envisioned scenario (initial gut feeling scenario) looked something like the following:

A disfigured lead, or lead with residual copper, bullet fragment flying forward escaped the limo from the third shot, at maybe 400 ft/sec, continued on to strike the curb with a compressive strike from a mostly horizontal trajectory, hitting at a reduced velocity around 200 ft/sec or so. This possibility was expected to be proven untenable and therefore likely wouldn’t happen.

Results:

Embarrassingly enough, the modeling predicted I would be wrong on every single account!

A fragment could have made it to Tague

The initial exit velocity would be more than twice the 400 ft/sec I was thinking

The final velocity would be even less than half the 200 ft/sec I was thinking

The angle at striking would be opposite, nearly vertical, instead of more horizontal like I thought

The curb strike likely presented a shearing force rather than the head-on compression force I expected

Talk about being wrong!

A crude curb-strike simulation was subsequently conducted to look at this because the predictions seemed so unusual.

Overall, the modeling and simulation indicated the scenario looked to be a real possibility, with a limo-exiting fragment able to reach the curb by Tague and cause a spray of surface mortar that could hit him.

It is still possible the model is not accurate enough, or the fresh mark was not related to a bullet at all, but the modeling came up with numbers that were largely predictive of observations that others subsequently measured on such fragments, like what Lucian Haag found for fragment exit velocities in his simulated skull test shots experiments, and Carcano fragment ballistic coefficients.

Two options for base case trajectories for the incident are depicted on the attached graphs. [I couldn't copy-paste them here. -- T.G.]

Based on the modeling and simulation, I now favor that a rogue fragment from the head shot caused the Tague incident.

I will try to make a link to a summary with more details for those interested in ballistics, etc.

The study details can be found here:

https://drive.google.com/file/d/1CcnCy17Hwqqw3zBCK7ls8peA3DxmVzhk/view?fbclid=IwY2xjawUJ9RtwZG9mAWV4dG4DYWVtAjEwAGJyaWQRMU9pYldIMmFVN1lEcWFHcVBzcnRjBmFwcF9pZBAyMjIwMzkxNzg4MjAwODkyAAEeAGcK-_z2CwDFyqPwaxNjySIe4271E_ylArwt4h0qfEuhMoRgvrWhDkoyXt4_aem_vfS9yrI0_vZnHC-27-PyIw

It sounds like the simulation framed the question correctly but it seems to me the figures are a bit arbitrary. How do you establish what the exit velocity of the fragments would have been. Did they just use a SWAG. I think somebody a lot smarter than me could calculate a reasonable exit velocity by determining what would have been required to pass over the windshield and still be moving slow enough that it would arc back down and strike the curb. Of course one would have to calculate the deceleration of the fragment as it passed through the air. The fact that they used round numbers indicates to me they just did a SWAG.

Another variable is how far above the windshield the fragment would have passed. If it passed just and inch or two over windshield it would need a different velocity than if it passed a foot over the windshield. All of this seems like so much guesswork. I'll stick to my gut feeling which leans toward the Tague injury being caused by a fragment from the first missed shot which struck the pavement to the right of the limo.

« Last post by Andrew Mason on Today at 03:42:37 PM »
It would have exited over the top of the windshield and gone on to hit the curb. The two large fragments found in the limo had gone upward upon exiting Kennedy's head. And they went there separate ways laterally. The one that hit the chrome piece was not far off from exiting. If it was a fragment that struck Tague , it would have had to go between 5 and 10 degrees to the left in order to hit Tague. I can't remember the figure and I can't check it out now because I've just been updated to the most recent version of GIMP and I have don't feel like trying to figure out how to use the measuring tool tonight. I'll delete this version tomorrow and download a much older one.

On edit: I just used the measuring tool in the latest version of GIMP. The fragment would have had to "deflect" 6 degrees to the left in order to hit the curb near where Tague was standing
We cannot assume that the strike on the curb was the first point of impact of the fragment after leaving the car.  Since the fragment struck the side of the curb and bounced up about 5 feet to strike Tague’s cheek, that suggests that it had an upward trajectory when striking the curb.  Since striking the curb would naturally result from a very shallow angle impact with the hard road surface, we cannot rule out the very real possibility that the fragment struck the road first, then the curb and then Tague.  If that occurred, it could have changed direction slightly after striking the road and before hitting the curb.  After all, whole the road surface may be uniformly flat to a basketball, but to a fragment, which may be smaller than the stones in the asphalt surface, it may not.

Perhaps you should learn to read. As I've noted and documented several times already in this thread, Dr. Young's first statements about the finding of a bullet in the limo and the bullet's appearance were written in his 11/23/63 hand-written essay "What Price a Rose?" So he wrote that essay on the afternoon of 11/23, less than 24 hours after the autopsy.

So you say but can't back up. The published version of that essay contains no such reference to a whole bullet received at Bethesda. No bullets or fragments were received at Bethesda. Several fragments were removed from JFK's skull and given to Sibert and O'Neill.
Quote

That wasn't even 40 hours after the fact, much less 40 years. It is revealing that you guys keep ignoring this crucial fact.

Unfortunately for you, there is no documentation which proves your claim.
Quote

Furthermore he wrote his letter to Gerald Ford in December 2000, not 2003, and he gave his first three Navy oral history interviews in 2001, not 2003. Additionally, he brought his 11/23/63 "What Price a Rose?" essay with him to those interviews and read from it during the interviews, as I've also mentioned and documented several times herein.

You've claimed but never documented that Young's notes contained a reference to a bullet being sent to Bethesda. Even if his notes did contain that, they would only reflect Young's confusion about what was in the envelope containing the recovered bone fragments. It would make no sense for the bullet fragments to have been handed over to the FBI but for some strange reason, they would send a whole bullet to Bethesda. There is no documentation which shows a whole bullet was recovered from the limo, only bullet and bone fragments.
Quote

And, of course, never mind that Chief Mills corroborated Dr. Young's account, right?

Wrong. He corroborated none of this. He refused to go into any detail about that night. You know that but keep lying about it.
Quote

Nice try. Loeffler was referring to two separate items: (1) the stretcher bullet, which O. P. Wright assumed had come from Connally's body, and (2) the fragments that were removed from Connally's wrist.

Umm, I already addressed Sibert and O'Neill's ARRB statements. Did you miss that? I notice you said nothing about the problems I noted with them. I also notice you said nothing about their HSCA statements. I also notice you said nothing about Boyers' claim that the evidence bottle contained three or four bullet fragments, not two, and that Sibert likewise indicated there were more than two fragments in his HSCA testimony. I further notice you said nothing about the fact that Sibert and O'Neill failed to say a word about signing for either a missile or bullet fragments in their 11/26/63 report on the autopsy. Let me refresh your memory, mainly for the sake of any newcomers and other readers:

Nobody cares about the problems you have imagined.
Quote

I find it strange that Sibert and O'Neill said nothing about signing a receipt for a missile or fragments in their 11/26/63 report on the autopsy. They mentioned that Humes removed the 7x2 mm and 3x1 mm fragments from the head but oddly said nothing about signing a receipt for those fragments. Could they have omitted this significant event from their report because they were uneasy about having signed a receipt that said "missile" when the evidence bottle contained only three, four, or a few more fragments -- fragments that clearly did not constitute the mass of a bullet? Or, did they omit this important event because by 11/26 the existence of a bullet or bullets at the autopsy could not be acknowledged? 

Nobody cares about what you have found strange.
Quote

- In 1978, along came Chester Boyers, the Chief Petty Officer at Bethesda who typed the receipt that Sibert and O'Neill signed. Boyers threw a bit of a monkey wrench into the cover story.

Boyers told the HSCA that he "submitted several missile fragments, probably three or four, all of which came from President Kennedy's head" (Investigation Interview, HSCA, 4/25/1978, p. 4, ARRB document MD 62).

He also said that "even though the receipt only stated that 'a' missile was given to Sibert and O'Neill, several fragments of a missile were submitted and that he only prepared one receipt" (p. 4).

But Humes said that he only removed two bullet fragments from the skull (from the right orbit), the 7x1 mm and 3x1 mm fragments, whose combined weight was only 180 grains, a small fraction of the mass of a bullet.

Boyers did not explain, and was not asked, why he would have used the term "missile" to describe several bullet fragments instead of just writing "three missile fragments" or "four missile fragments."

There seems to be a discrepancy as to how many bullet fragments were recovered at autopsy. It isn't relevant to the discussion of whether a whole bullet was delivered to Bethesda. The only "evidence" of that are the recollections of an old man who was probably confused from the outset. Nobody else has said a whole bullet was found in the limo or delivered to Bethesda. You continue to try to conjure up evidence based solely on the 38 year old recollections of a confused old man.
Quote

-- When Sibert was interviewed by the HSCA in 1977, he made a number of statements that contradict the cover story. He referred to more than just two fragments, saying "a lot of the metal fragments were tiny," that "all that were removed" were put in a "jar with a black top," and that they signed a receipt for those fragments (Memorandum: Interview with James W. Sibert, HSCA, 8/29/1977, p. 4, ARRB document MD 85).

So clearly we have a major conflict in the record. Both Boyers and Sibert said there were more than two fragments.

Why do you keep redirecting the conversation to the number of bullet fragments that were found during the autopsy. The issue which you raised in the OP is whether or not a whole bullet was found in the limo at the White House garage and then delivered to Bethesda.
You expect the LNs to explain something you have never established as fact. The evidence indicates only that bullet fragments were found in the limo and they were given to the FBI.
Quote

-- When Sibert's HSCA interviewers (Jim Kelly and Andy Purdy) specifically him asked about the receipt for a "missile," he actually criticized the receipt's author and its wording, saying that the receipt "was prepared by someone else," that he "would have listed the items as metal fragments," and that to him "a single 'missile' means quite a bit of substance -- more of a whole bullet" (pp. 4-5)!

We are left to wonder why the HSCA interviewers did not ask him the obvious follow-up question:

"If you thought the receipt was so inaccurate, why did you sign it? Why didn't you just tell the guy to retype it so that it read 'fragments' instead of 'missile,' since this would have only taken a few minutes?"

Apparently the HSCA members weren't as anal as you.
Quote

-- Things get even more curious and suspicious when we consider O'Neill HSCA affidavit.

O'Neill said the "saw" the autopsy doctors remove a fragment from "further back in the head" (O'Neill Affidavit for HSCA, 11/8/78  p. 4, ARRB document MD 47).

Once again you redirect the conversation to the bullet fragments and away from your bogus claim that a whole bullet was recovered during the search of the limo.
Quote

This was undoubtedly the back-of-head fragment that Sibert and O'Neill mentioned in their report on the autopsy; they said this fragment was the second-largest fragment in the skull (p. 4). This is surely, unquestionably the very thin 6.3 x 2.5 mm fragment that Dr. David Mantik discovered inside the ghosted image of the 6.5 mm object on the AP skull x-ray via optical-density measurements and high-magnification viewing. This fragment also appears on the right lateral skull x-ray (but it is -- impossibly -- much smaller than the 6.5 mm object).

But Dr. Humes never admitted that he removed a bullet fragment from the back of the skull. He said the only two fragments he removed were the 7x2 mm and 3x1 mm fragments that were very near and slightly above the right orbit.

-- O'Neill added that "a Navy man" made the receipt for the back-of-head fragment and for a fragment that was removed "from just behind the eye," that he and Sibert signed the receipt, and that the doctors did not remove a "full missile" (pp. 4-5).

O'Neill knew that the autopsy doctors removed two fragments from the right orbit -- this is mentioned in his and Sibert's report on the autopsy (p. 4). I suspect O'Neill knew what he was doing when he informed the HSCA that he saw a bullet fragment removed from the back of the head and that it was one of the fragments for which he and Sibert signed.

If the HSCA medical-evidence investigators had been doing their jobs, O'Neill's disclosure should have raised some huge red flags about Humes's version of events at the autopsy.

You sound desperate as you flail away aimlessly.
Quote

I think all of this suggests that Sibert and O'Neill were pressured to go along with the cover story. They were never willing to repudiate it, but they were willing to reveal information that raised serious doubts about it.

-- When Sibert and O'Neill were interviewed by the ARRB, they disclosed a lot of important information that destroys the single-bullet theory and the WC/HSCA claims about JFK's head wounds. But, they were unwilling to contradict the story that the receipt they signed referred only to the two fragments that Humes removed from the right orbit of the skull, even though they had previously revealed information that contradicted the story.

O'Neill offered a particularly lame excuse for signing a receipt that used the term "missile" to describe fragments:

Now I know there's been some controversy also about. Because we saw them put into a jar, and Jim and I signed for that jar. We signed for a missile. That was exactly what the Navy terminology is for a bullet -- anything which flies through the air is a missile.

It's changed since then because they now have the guided missiles and things such as that. But at that time anything which went through the air was a missile. And that's the way they wrote it up and that's the way we signed for it. (Deposition of Francis X. O'Neill, ARRB, 9/12/1997, p. 78)


Now, I'm sorry, but that's pure poppycock. If we were only talking about a single fragment, O'Neill's excuse would at least be minimally plausible, but neither the Navy nor any other government entity ever used the term "missile" to describe multiple bullet fragments or even multiple projectiles of any kind. Yes, the word "missile" was indeed Navy terminology "for a bullet," but we're not talking about a bullet, and O'Neill was not signing for a bullet.

The excuse Sibert offered was not much better:

I'd like to elaborate a little further on this. Here we get to this term "missile."

Now some things I've read about the agents giving a receipt. This receipt was prepared by Navy personnel. I think a Navy corpsman typed it up.
 
And this terminology is U.S Navy about the "missile." Now had I been preparing or making out a receipt and giving it to them, I would have said "fragments" here. (Deposition of James W. Sibert, ARRB, 9/11/1997, pp. 89-90)


At least Sibert once again admitted that he would have used the word "fragments" in the receipt, and not "missile," but he repeated O'Neill's specious suggestion that the Navy would use "missile" to describe multiple fragments of any kind. 

Sibert and O'Neill offered no explanation to the ARRB for why they would have signed such a markedly inaccurate receipt in the most important murder case of the century. Their answers smack of guilt and excuse-making. They obviously proved in their 11/26/63 report on the autopsy that they knew that "missile" was not a synonym for "fragments." They themselves distinguished between "missile/bullet" and "fragments."

It is hard to imagine that two FBI agents would have signed a receipt that said "missile" when they could see that the evidence bottle only contained two small fragments, especially when the fragments constituted only a tiny fraction of a bullet's mass.[/font]

The fact that you want to focus on how many missiles Sibert and O'Neill received is an indication you know how weak your case is for a whole bullet having been recovered from the limo and sent to Bethesda.
Quote

You guys just refuse to process and deal with contrary facts that refute your lame explanations.

Nothing you claim is fact. Just your wild speculations.
Quote

You want so desperately to reject Dr. Young's account that you repeatedly ignore facts that strongly support it, and just keep repeating your lame excuses, even after being forced to admit that Mills and Martinell did in fact search the limo at the White House garage, and even when faced with the fact that Captain Stover recalled that a bullet was brought to the autopsy in an envelope.

There is no evidence that supports Young's belief that a whole bullet was delivered to Bethesda. You have made a vague, undocumented claim about Stover confirming a bullet was brought to the autopsy without any cite where Stover said he saw such a bullet or how he would have known about it. In lieu of such evidence, we can dismiss this as more of your  BS:

JFK Assassination Discussion & Debate / Re: The First Shot
« Last post by Tom Graves on Today at 02:51:23 PM »
While that is a possibility, it requires that a fragment exited JFK's head with a low enough velocity to pass over the windshield and arc back down to where it struck the curb in front of Tague but still have enough velocity to cause the debris to injure Tague. I don't know if there is a velocity that would satisfy both those requirements. I tend to lean towards the theory that the first missed shot fragmented and one of the fragments ricocheted down range to strike the curb. Using Google Earth, a line drawn from the sniper's nest to Tague's location would passes just to the right of where the limo was on Elm St. I believe that the first shot struck the pavement to the right of the limo. Posner hypothesized the bullet hit a tree branch and others believe it hit the traffic arm that the limo passed under. We will never know for sure what the cause of Tague's injury was, only that it was likely a lead fragment from one of Oswald's shots.

TG--

If what you and John Newman suspect is true about Solie, then Solie is the perfect candidate to leak info to Garrison...that Garrison would naturally believe, given the source.

Somebody inside the CIA leaked to Garrison that Shaw had a history with the CIA.

The KGB "CIA perped the JFKA" narrative in full flower.

In fact, Shaw was possibly monitoring LHO in New Orleans, just as de Mohrenschildt had in Dallas (although De M. may have been a double agent).

You're all mixed up, dude.

Grok and ChatPGR's chatbots are meant to be machines that will agree with whatever SFW thing you say, regardless of contradictions, so if we are gonna solve Kennedy getting shot, we use humans instead of machines that speak 0s and 1s.

The claim that the acoustics evidence found on the Dictabelt recording shows a fourth shot has been thoroughly debunked in so many ways. The following is as good as any:
 
https://www.jfkfiles.com/jfk/html/acoustics_2.htm

Going to the homepage will also give you access to Dale Myers 3D animation of the shooting.

The sources I cite in my reply refute every single criticism presented in the article you cite, Dale Myers' article. You'd know this if you'd bothered to read the links I provided. If you had just read my article on the acoustical evidence, you'd know that Myers' article is woefully inadequate and misleading.

And for the benefit of other readers, be advised that Dale Myers' research has been proven to be erroneous, if not fraudulent. As just one example, to make his ridiculous SBT trajectory analysis work, Myers falsely assumes that Connally's back wound was 3.0 cm wide, when in fact it was only 1.5 cm wide, the same width as JFK's rear head entry wound.

For a good critique of some of the problems with Myers' bogus research, see the uber-cautious Pat Speer's demotion of Myers' SBT nonsense:

https://www.patspeer.com/chapter12canimania

Here is just a little bit of what Speers says about Myer's SBT simulation:

. . . his deception regarding the single-bullet theory is simply inexcusable. He would have to know that when people see computer simulations they believe the proportions are consistent from angle to angle—otherwise it’s just a cartoon. By changing the body shape of Kennedy to accommodate the bullet trajectory through his body, and by shrinking Connally 20% or more to accommodate the bullet trajectory in the car, Myers moved on up to the high rent neighborhood of Thomas Canning: deliberate deceptionville.

For a critique of Myers' error-riddled hatchet job on the Tippit shooting, see my article "Did Oswald Shoot Tippit?"

It says much that you would rely on someone like Myers to get your information on the acoustical evidence. Have you even read the studies that the BBN and Queen's College acoustical scientists submitted to the HSCA on the acoustical evidence?

Myers obviously hasn't read them, because he doesn't say a word about any of the evidences they present, such as the windshield-distortion correlations, the timing-movement correlations, and the presence of N-waves and their echoes in the correct order and timing. Nor does Myers say a word about the NRC/NAS panel's admissions about the timing-movement correlations and their own finding of a high probability (77.7%) that the 144.9 impulse pattern is gunfire from the grassy knoll.

New here.  Can someone please direct me to on this forum or explain the apparent contradiction that J. Thompson uses acoustic evidence in his book, The Last Second in Dallas,  and the previous work that claims to debunk the Dictabelt recordings. Thanks.

I address the attacks on the acoustical evidence in my article "The HSCA’s Acoustical Evidence: Proof of a Second Gunman in the JFK Assassination".

By "the previous work that claims to debunk the Dictabelt recordings," I'm guessing you're referring to the NRC/NAS panel's critique of the acoustical evidence. The panel, aka the Ramsey Panel, did not include a single acoustical scientist, and virtually their entire case rested on the debunked claim that the Decker "hold everything" transmission was crosstalk and that the transmission proved the sound impulses were recorded 30-60 seconds after the shots were fired.

Dr. Thompson arranged for new research by BBN acoustical scientists from 2015-2018 that refuted the NRC claim about Decker's transmission and that verified that the Fisher "I'll check" transmission is actual crosstalk and that it proves the sound impulses were recorded during the shooting. He discusses this new research at length in Last Second in Dallas. Two BBN acoustical scientists wrote appendices in Thompson's book.

Also, it's worth noting that the NRC/NAS panel admitted (as obliquely as possible) (1) that they found a 93% probability that the timing-movement correlations identified by the BBN scientists between the dictabelt and the recording of the test firing in Dealey Plaza occurred because the dictabelt recorded gunfire in Dealey Plaza, and (2) that they found a 77.7% probability that the 144.9 impulse pattern, identified by Weiss and Aschkenasy as gunfire from the grassy knoll, was in fact gunfire from the knoll. You'll notice that critics of the acoustical evidence never, ever deal with this fact.
