She said the first shot didn't hit anybody in the limo. Deal with it.
If the first, "backfire-like" shot had hit JFK or JBC, Woodward would have noticed it.
She said JFK "slumped" after the second shot, and that Jackie stood up and fell on top of JFK after the third-and-final shot.
Although Woodward was wrong to say that JFK and Jackie turned, smiled, and waved at her and her three colleagues
before the first, missing-everything, shot, she was correct in saying that
both of them turned, smiled, and waved at them at some point.
As to when, exactly, they did that, we can see that JFK, having just turned his head back from his left to his right, is waving at them from about Z-175 on, and we can see that Jackie, who was looking to her left until about Z-175, is looking straight-ahead-ish in Z-180 and has turned her head far to her right in Z-190 (presumably she isn't scowling at Woodward and Co. and giving them the finger, but smiling and waving at them, like her husband).
Jackie is still looking far to her right when she emerges from behind the Stemmons Freeway sign in Z-221.
