DB Cooper in Skydiving History & Trivia February 10, 2014 BruceSmithQuote"...This may sound obvious, but I don't think a SOG guy would come to the Cooper party dressed in a suit and loafers..." Bottom line, Bobby. Do you think a SOG trooper could make it to the ground wearing loafers and a business suit? If you say yes, then why wouldn't such an operative wear the best disguise possible to get himself on a 727 undected in PDX at Thanksgiving. One could see it as a brilliant disguise. With layers underneath, even in those days they new that method. The stairs operation incident would rule out any one who flew on those planes for a living and had operated them before. It could also rule out any one directly involved in any super secret agent guy testing, wouldn't you say? Now a well trained SOG guy who heard of the testing, bingo. Or a some what researched skydiver, who had a little survival knowledge, oh another bingo! Of course those two types can be placed in training and parachutes. One could even say, an old has been, who just speculated as he sat on the ramp one day that the stairs could be lowered. Then he hatched an idea, and drew on his old military training for parachute choices. After watching a Stewardess lower the stairs on a previous flight, figures he has it all worked out. The hard part, putting a name on the criminal who was acting as a terrorist. So far, that has not happened, not even in this thread. MattAn Instructors first concern is student safety. So, start being safe, first!!!
