D. B. Cooper and Flight 305: on WanderLearn
The second of three episodes of D. B. Cooper and Flight 305, with Francis Tapon and myself, is live on the WanderLearn channel at https://www.youtube.com/watch?v=BsXtD... (video file) and https://www.youtube.com/watch?v=9gR86... (audio only).
We start with an outline of some elements of the hijacker's planning process, and the criteria that led to his choice of Northwest Flight 305.
We go on to discuss the precursor flights, by Boeing out of Hoquiam and Boeing Field, and by Southern Air Transport (fronting for the CIA) out of Takhli, which demonstrated that it was possible and safe to parachute from a Boeing 727.

Every word on this blog is written by me. Nothing is generated by so-called "artificial intelligence": which is certainly artificial but is not intelligence. ...more
