According to the current version of the SBT, the first shot missed the entire car.
However, not only is there no clear evidence that the first, or any, shot missed missed, there is abundant clear evidence that the first shot struck JFK in the back and traversed his neck. There is also evidence that the second shot struck JBC. The preponderence of evidence is that the second shot was closer to the third. There is also evidence from George Hickey, that the second shot just passed to the right side of JFK's head as he saw JFK's hair on the right side lift at the same time that the second shout sounded. And there is abundant evidence that the head shot was the third and last shot.
So, according to the evidence, Oswald was pretty accurate on all three shots.
Not your George Hickey crap again.
Even if Hickey had fully stood and got his head turned around in one second (the time span between him with his head turned quite far towards the rear as shown in the Altgens Photo and when Mason has Hickey "seeing" the President's hair flutter in the Z270s), Hickey couldn't see where Kennedy's hair fluttered because the President's head is tilted forward. It's just a tiny amount of hair in the Z270s that bounces up 1/2 inch for one frame and then falls downward. A 1/18th second event wouldn't make this much of an impression on Hickey: "the hair on the right side of his head flew forward".
"The first shot of the second two seemed as if it missed because
the hair on the right side of his head flew forward and there didn't
seem to be any impact against his head. The last shot seemed to
hit his head and cause a noise at the point of impact which made
him fall forward and to his left again. - Possibly four or five seconds
elapsed from the time of the first report and the last."
Maybe an impression Hickey had of the head shot and the scalp flying away from the President's head. Later on, he mistakenly applied it to an earlier shot. Or Hickey could be accurate but he's referring to the second shot in the early Z220s. That is when Hickey could clearly see the President's hair suddenly bounce, during Kennedy's reaction to the Single-Bullet strike in the early Z220s.
