Motorcade 63 is a nifty piece of JFK research from programmer Mark Tyler.
Tyler has reconstructed the passage of the President Kennedy’s motorcade through Dealey Plaza on November 22, 1963 by combining photographic and eyewitness evidence. He explains his transparent methodology and his conclusions here.
In a note to researchers Tyler says this:
Over the next few months I hope to add more key witnesses and fine tune the work so it is consistent with the factual record (i.e. photos, films, and corroborated witness statements). People are welcome to offer advice regarding how to improve the work.
Working on this project has helped me understand the events from 1963 in much greater detail, and I hope others find the animation useful for their studies too.
