Concluding, I've a hunch that "D.B. Cooper" hijacking may be imitated possibly in the [guess: Spring], and unlikely out here on the West Coast. This suggests that all parachute [guess: drop] training schools from now on should [guess: stop] thoroughly investigate new applicants. The next "Cooper" might be younger, possibly a Vietnam veteran of the Air Force. Why? Because 1) more recent experiences and 2) tougher? (It is not many people who can dive out of a plane at anytime — even to save that lives if the plane caught on fire.)
There was [guess: possibly] something in this man's behavior that those who saw him (ticket seller, airline hostess) still know, but don't realize they do, or believe unimportant. Did "Cooper" differ from most passengers in any way at all — more friendly, more talkative, etc to etc. Could he once have been an employee of the airline he hijacked?
Many [guess: people] have creative ideas of protecting airplanes from just such an act as "Cooper's", but who can copywrite an idea? And payment for a good idea would be little if anything. So creative ideas die a-borning. I've such an idea, but wouldn't offer it don't even if [guess: perhaps] [guess: Perhopes] through a "[guess: muni] tank" like RAND. I might give my suggestion. The latter would know if worthwhile (and see payment was [guess: fitting]). But I consider this a longshot — a pipe dream!!
As a veteran, as an American whose ancestry dates in America to 1610 — I hope you catch this criminal. W. W. Jerrett
