By my rough calculations explained in the earlier post, the end of the traffic light mast (where the actual traffic light is hung) is roughly inline with a pseudo Z124 JFK location. Again, others can probably provide more accurate plots of these locations than I can at this point.
There seems to be some confusion about the minimum limo miss at ~ z124 I have been talking about and the traffic mast causing the miss at ~z107.
The minimum limo miss is described at this link below with the middle picture representing the limo at ~z124.
At this point the limo has significantly passed the traffic mast. This type of minimum miss strike location also matched what Faye Chism said.
This link below was used to estimate the instantaneous rifle deviation, i.e. how far off from being perfectly aimed using the iron sights it would momentarily have to be off target to miss the limo, when the first shot missing the president’s head was estimated at 36”. The picture at the top was found to just to help convey the geometry of the measurement points. The result was that the aim only had to be off target by about a half an inch to miss the limo.
I later made an estimate using oa at 107 ft to get some angle estimates. If it helps, one estimate of the angle down from horizontal at the sniper nest to the trajectory going to limo was about 33.7 deg, and upwards from ground/limo to the nest would be about 32.8 deg.
