Hickey can't be referring to the hair flutter in the Z270s because he can't see it. Furthermore, per your theory, Hickey has to turn his head completely around and locate the President then and observe some incidental thing as a hair flutter, all in one second.
He said he saw it. He was there. Unless you were in his position in the QM you really have no idea what he could see. He has a second to turn to see the President after the Altgens #6 photo. There is his evidence that he made that turn and nothing to contradict it. The fact that the hair on JFK flies forward from z273-276 at exactly the time that JBC's cuff changes appearance and the visor over Greer moves and Greer begins his turn (immediately after the second shot), all fits together very well with what Hickey said he saw. How could he make that up without studying the zfilm? Or are you suggesting he studied the zfilm prior to Nov. 30/63?
The sailing forward began in the Z260s. It could have increased in intensity simply because his center of gravity is more upright. Doesn't have to be from a bullet impact.
JBC appears to raise his head and shoulders but I don't see any increase in separation between JFK's face and JBC's face prior to z272. After z272 the increase in separation is rather dramatic (see below).
Your animation adds forward momentum to Connally's body that isn't there.
Watch from z271-279 the relative positions of Jackie, Nellie and Kellerman and then look at JBC's position to all three. If I was adding momentum to JBC I would be adding it to all four. But JBC's position relative to the other three changes noticeably but the relative positions of the other three does not change:
And the "change in appearance of the wrist" seems downgraded to "amount of visible cuff increases".
The cuff of the jacket was penetrated by a bullet, as was the shirt. One might expect the jacket cuff to move more than the french cuff because it would not be as tight. z271-273 is the only place such relative motion is seen. That is not light and shadow. It may be that hand motion could cause that kind of relative motion, but we don't really see the wrist move much, although if you watch the lower part of the hand there appears to be a slight change there with the fingers:
Was that visor struck by a bullet fragment.
There is nothing that I have found that comments on damage to the sunvisor. But looking at the damage to the windshield frame and the glass indicating several fragments struck inside, plus the fragment that struck Tague. It would be surprising if the visors were missed. There does appear to be small hole-like marks in the left visor in the only photo I have found of the visors:
There is also a mark that appears on the front side of the left visor in z272 although that may be a film artifact. The resolution is not good enough to see the windshield frame clearly but it looks like there is a change from z271-272 in the top of the windshield frame.
Too bad the particular visor you choose to indicate a fragment strike happens to be the same one that's rocking back-and-forth as the car approaches the Z270s. Obviously the air pressure.
It doesn't move afterward. It only moves from z271-272 and then goes back to its z271 position. How can that be by air pressure? It wasn't flopping around. Sun visors are designed to stay where they are set.
