Are you serial? Admit it, you don't know what you're talking about, do you?

Jack,  why don't you, as our resident physicist/photogammatrist, explain to the rest of us here how the entry wound being 2 inches to the right of the spine gives the EXACT lateral (pitch) angle of trajectory? Go ahead and dazzle us.

Humes says the back wound was 2" right of the spine.  According to SBT, this bullet then exited midline in the neck.  That's 2" displacement for about 6" forward.  By the time it moves 24" more, to the plane of Connally's back, it should have displaced 8" to the left of JFK's neck.  In my opinion, there is no way this could hit Connally on the right side.

That seems like an intelligent and rational conclusion......

That is false.

Going Ballistic

Pretty sure a bullet starts to drop the moment it exits the barrel. It's called gravity.. plus air density, temperature, and wind have an effect on the flight of the bullet.

Seems the guy on the whoopee cushion is, ironically, a fine representation of yet another CTer lame attempt to prove this, that, and the other.

At least he makes an attempt to prove something, much unlike yourself, who only offers opinions.

Show me where I said I could prove anything here. And tell us why you need people to prove something to you.

It seems to me that you characters are the ones casting opinions around. If you have a problem with gravity, maybe read what Newton's and Einstein's opinions are on the subject.

It doesn't give us the pitch of the MB trajectory, but it does give us JFK's orientation when he was struck by the (cough cough) MB. We know the pitch of the MB thru geometry (and not "photogammetry", whatever that is) and the position of the limo at frame z224 relative to the SN. The pitch angle was -7 degrees. Since the angle thru JFK was say >12 degrees (2 inches right of his spine) we know that JFK had to be turned to his RIGHT 5 degrees relative to the limo to form a -12 degree bullet trajectory from his back to his throat. This was clearly not the case so what do you propose resolves this discrepancy?

How does it give JFK's orientation when he was struck by the single bullet?

You're not making any sense at all.

The bullet does not automatically start to rotate when it exits a human body. A bullet tumbles in response to interacting with a solid object such as bone that deflects its trajectory. It does not deflect appreciably when it transitions from one medium to another such as flesh to air or water to air, etc. It certainly doesn't rotate appreciably within a couple of feet of exiting the body.

Otherwise, a bullet follows a parabolic path like anything else under gravity. The mussel velocity defines the parabolic arc of a projectile, which is insignificant over a hundred feet and has nothing to do with a tumbling bullet.
