DB Cooper in Skydiving History & Trivia July 10, 2013 As to point 1, it has been proven over and over, eye witness testimony is flawed at best. Point 2, a year is a long period of time if the Doc said he was there at the time of the actual hijacking, you may have a point. Point 3, they can still circle back if they find more evidence, a lot of times the best suspect is the right suspect, even if they move on to others, just to rule them out. Point 4, Sheridan did a jump dressed just like this right? The order to take off with the stairs down supports your assertion he was planning on leaving quickly. I have seen people jump in wedding outfits, dress shoes and all, so he foot wear? That is no big deal. Point 5, if he had SOF connections, easily done, at least back then. Point 6, Correct. Point 7, actually, if he is looking for paracord, he would know the dummy would be a poor choice. If he was sure it was an all "on the main" ride, he didn't have a plan for the reserve anyway. He seems to have had a risk reward plan in effect. So far, he is the only one who has the actual training, experience, and audacity. All the rest, can't even be placed in the training (confirmed at least). MattAn Instructors first concern is student safety. So, start being safe, first!!!
