skyjack71 0 #24776 August 9, 2011 Quote Previously, Cooper could have been imprisoned for armed robbery and found out about the 727 jump capability from a cell-mate. Someone who had actually done that stuff before in the military, and had plenty of time to tell him all about it, about how you'd need flaps down and to stay below 10k feet. Afterward the FBI is checking skydivers, ex-military, pilots, laid off Boeing employees, rogue CIA smokejumpers and the like, but never thought to check and see if some convicted felon, recently released back east somewhere, had vanished. Cooper could have been in prison for so long that by the time he got out, there was nobody around to notice him missing at Thanksgiving dinner. This is exactly the same story I told the FBI over and over and over....I had multiple conversationg with Mr. Himmelsbach about this. I kept asking Mr. H (remember I thought of him as being FBI) to check to see who Duane knew in prison...and who was there when he was. The FBI ignored me...in my pleading phone calls. Remember I did NOT have a computer - and I could NOT afford to spend long lenghts of time on the phone. The reason I asked him about Jefferson was the stories Duane told me about Jefferson - after 1990...after he came home. This is when he tried to get the John Collins ID and I found out about Jefferson. Although I did NOT push him with questions about Jefferson the conversation was one he related on his own. I may have asked him how horrible it was in a prison and what they did. This was when he told me about their sitting around planning "the big one". He did not mention names that I remember. He also told me that James Earl Ray was there. Duane did mention war veterans and pilots who had been given a raw deal, when they got home. Remember at that time I had NO idea Duane was Dan Cooper...and he could have spelled it out for me and it would NOT have hit me. When I say "Most Likely to Get Lost in a Crowd" I am NOT kidding. I was a really naive person. Smart book wise. Remember this is a title that was given to me in High School....so it goes WAY back.Copyright 2006, 2007, 2008, 2009, 2010, 2011, 2012 2013, 2014, 2015 by Jo Weber Quote Share this post Link to post Share on other sites
skyjack71 0 #24777 August 9, 2011 Quote If Cooper survived the jump, after the statute of limitation expires there would be a huge financial incentive to "come out". If he were to claim responsibility I can imagine him selling his story and basking in the glow of out smarting everyone. But that never happened because Cooper was probably a solid citizen with a productive life. I can see him being ashamed of what he did. He was from a generation that did what they were suppose to do. Why would he go off the rails like this? I don't know. You must be Marla or one of her family because YOU do NOT have a CLUE: There were NO statue of Limitations. If you are going to make statements like that - PLEASE do your homework. I will let someone else explain this SIMPLE fact to this uninformed person. So sad when someone makes such comments!

georger 197 #24778 August 10, 2011 QuoteQuote No, Cooper was from Oregon or Washington. He knew the land, he knew roughly where he was despite the fog. He had been on flights from Portland to Seattle many times and recognized what Tacoma looked like from the sky. He had jumped from planes many times but mostly as a younger man. I imagine in 1971 you could not fly out of the United States from Portland, or you had very little choice, maybe to Canada, but to fly to the orient or other international destinations you would fly to Seattle first. I agree that it seems to make sense that he would have known the area. Add that with his choice of chutes and a picture is emerging. Seems logical, but what if those assumptions are wrong? What if the part about recognizing Tacoma from the air isn't as clear or as significant as it seems? If Cooper overheard a passenger mention it or guessed from seeing it on a map? The FBI was investigating people based on what might seem to make obvious sense, maybe they were looking for the wrong person due to making the wrong assumptions. Those being that he was a jumper at some point, probably ex-military, some kind of aviation experience, and that he knew the area. He could have been all those things and still off the radar somehow, but there's no actual proof of any of these things, they are just guesses, so they could all be wrong. All he factually needed to know about the plane, somebody could have told him. Jump from a 727, make sure it is flying low and slow, and watch out for air marshals. I do think if Cooper was from or knew the area well, even with fog he'd have an idea where he was jumping, at least from lights from the interstate and the glow from Vancouver and Portland. If Cooper was a pilot then he'd probably have a very good idea where he was. QuoteHe was quiet and efficient and had nerves of steel, which were aided by nicotine. He used exactly the right amount of words to convey his message to Tina, no more, no less. That efficiency and confidence makes it seem like he'd done this kind of thing before, not a hijacking, but some kind of planned crime. Clearly he knew what he was doing up to a certain point, but that may not mean he was a skydiver or spent much time in the air. He sure didn't want to reveal much. Maybe he was also masking a regional accent by saying little. There were no prompts for his use of Tacoma. That was spontaneous on his part. Wondering why the chutes were taking so long. Some connection to Tacoma in his mind. Tacoma only 20 miles away - where are the chutes!? (not the kind of remark Kenny would have made, either). Underneath the calm exterior is an anxious person pissed at times. Then he misses the next tell - fuel snafu. Normal refueling/cleanup turn around time about 15-20 mins max, normally. He sites and say nothing at first. Someone experienced with the NWA turn-around time at SEA would have caught that quickly. Vapor lock? There are other tells at work ...

Also, I'm not sure how much even a retired SA could do to to stir things up without some irrefutable piece of evidence. Quote Share this post Link to post Share on other sites

Robert99 replies: For starters, somebody would have to tell him to select a 727 since it was the only airliner in operation at that with an aft stairs that could be lowered in flight. And that information was very closely held. NWA didn't know that and even some Boeing people didn't know that. To jump from a 727 does not necessairly require that the aircraft be going slow and you wouldn't want it to be very low. Air marshalls were not a factor at all in this hijacking. G_Jones writes: I do think if Cooper was from or knew the area well, even with fog he'd have an idea where he was jumping, at least from lights from the interstate and the glow from Vancouver and Portland. If Cooper was a pilot then he'd probably have a very good idea where he was. Robert99 replies: It seems to keep getting lost in the translation that there was an overcast at 5000 feet with about three other layers of clouds below that. The airliner crew has been quoted in several places as saying that they could not even see the glow of lights from Portland as they passed nearby. They certainly would not have been able to see cars on the Interstate. Pilot or not, Cooper did not have any means, except a wild eyed guess, as to his geographical location when he jumped. G_Jones writes: He was quiet and efficient and had nerves of steel, which were aided by nicotine. Robert99 replies: His "nerves of steel" were also aided to some extent by some bourbon and soda (or whatever), except that he reportedly spilled about half of the liquor.
