Bear in mind, folks, Orr's analysis is dated 1995. I have no idea what tweaks he may have made in the intervening 30 years. This is why I wish Larry Schnapf would weigh in, since he thinks enough of Orr's analysis to have been working with him for years. I posted Orr's analysis only because someone was questioning whether there is, in fact, a Knott Lab "study" underlying the Knott Lab animation. Since Orr commissioned the work by Knott Lab, I assumed his analysis was the basis of the work and thought others might find it interesting. Since Schnapf and Orr are apparently working on a new animation, it will presumably reflect the current state of their thinking on the shots. I found, and still find, Orr's analysis to be impressive and interesting, but I did not start this thread as an Orr apologist. If you think Orr's analysis is flawed for reasons other than knee-jerk, quasi-religious LN zealotry, that's fine; as a provisional LNer, I find the SBT and the LN medical/ballistics analysis in general to be considerably less than compelling. Last time I checked, the "experts" couldn't agree as to what part of JFK's skull the Harper fragment was from, and the HSCA "experts" placed the head wound something like 4" higher than the autopsy doctors.
