They may have used both the movie, but the Citation in the picture that you posted, is a Citation V.
The 700 is an Aerostar, made by Piper. I don’t know about the widow-maker part. My experience has been it’s an honest airplane with a high wing loading. It flies pretty good on one engine (personal experience).
Throughout 1962 and 1963, the U.S. military extensively tested the AR-15. Positive evaluations emphasized its lightness, “lethality”, and reliability.[17] However, the Army Materiel Command criticized its inaccuracy at longer ranges and lack of penetrating power at higher ranges.[43][37][17] In early 1963, the U.S. Special Forces asked, and was given permission, to make the AR-15 its standard weapon.
The Secret service was using this “new rifle”. In 5.56.
I guess that’s where the facts are disparate. I kn ow I was a documentary that showed pictures of the entry wound. I could be wrong, or maybe misled.....
Moreover, the bullet that blew JFK’s head apart was a frangible round. Not like the “magic bullet” slug that Oswald fired and stayed intact after going through JFK’s neck,a seat back, and Connelly’s back.
If that were the case, the entry hole in the base of JFK’s skull would have been the same diameter as the caliber of Oswald’s rifle. It wasn’t. The entry hole was smaller, about 5.56 size.
