Color film found of Air Force One arriving at Andrews AFB on Nov 22, 1963

Robin Unger posted color images of Air Force One arriving at Andrews AFB on the night of November 22, 1963 over on the Education Forum.  There are two clips at this site Critical Past.  Clip one shows this bright yellow truck going up to the rear of the plane and then JFK's casket is put on that.  It's lowered and we see several people inside behind it.  Jackie and RFK come into view.  JFK's casket is placed into a grey Navy ambulance and then it drives off.  Clip two has LBJ walking over to microphones and he talks. Unfortunately, there really is no sound for either clip.

I've never seen these scenes in color before.
