FLYJACK

when Larry said there are no conspiracies in the Government.. I had to chuckle..

Larry makes a common error, he assumes the only time a bill is potentially checked is when it is initially spent.. the bills were entered into NCIC and circulate for years until potential destruction.. there are many points in its lifecycle that a bill can be caught. If there were almost 9700 bills in circulation for years one would have turned up somewhere.. I agree with the numismatist on this.. Cooper, lost the money, hid the money or took it out of the country.. This is interesting,, one theory I have is that Cooper lost the money and it was found by somebody who didn't turn it in but couldn't spend it..

Clearly and understandably Larry isn't as up to date on the case as we are.. The FBI mandate is to bring a prosecution.. so their goal is inherently "actionable" but this case will never be prosecuted now. Larry said.. Soderlind noted ATC Portland stated the plane was East of V23,, not the pilots.. we have previously found that document.. "1-2 miles East of the center of this particular flyway".. not in the Washougal basin but within V-23 corridor and consistent with the "FBI" flightpath map .

Great episode.. will be a classic.. I wanted to interrupt so many times.. Cigarette butts were destroyed not lost per FBI file. Cooper's initial demand was airstairs lowered inflight. Later changed. Dan Cooper comic was published in Mexico in Spanish for Latin America... Bonus points for rejecting Ulis's western flight path. and the chutes,, what about the two backpack cards, one was the chute Cooper used... plus Cossey's serial lying, the FBI was looking for the wrong chute. Larry said they were going to go out over the water even going to Reno,,, remember Cooper rejected SF and LA because they were large airports, why if he was jumping in PNW.. Interesting that the tie is considered useless now,, that is the only way to get a 100% solve.. Larry will get a big surprise when my research comes out... I don't do facebook, Larry should post here, the crazy people are gone.

Yes, he must have been fully confident that the airstairs could open inflight. Other versions of the 727,,, there was a single prototype military sub hunting version that was never in production and 5 C-22's which were in the National Guard but don't know if the airstairs were operated differently, can't find that info. IMO, Cooper had military aviation experience but not any directly with the 727.. he may have heard about a 727 drop operation in SE Asia or have been indirectly involved. To get this thing solved 100% the only way is to obtain new DNA from the tie and match it to a suspect but that may not be possible due to the FBI or degradation/contamination of the tie.

Based on all the info we have it sure seems that Cooper was confident the airstairs could be lowered inflight but did not have any experience with them.. He must have read or heard about the 727 airstairs opening inflight...

The Boeing airstairs report starts p. 333 to p.356 FBI files part 71.. Takeaway,, if I am reading it right. The airstairs were dropped in two modes at various speeds.. they were "unlatched" with gravity which is done by not pressing the button on the lever and then hydraulic assist by pressing button and moving lever to down position. (IMO, Cooper initially had trouble because he didn't press the button on the lever) With gravity "free floating" the drop was 8.6 degrees. (125 knots) With hydraulic assist the drop was 13.5 degrees. (125 knots) No excessive pressure was noted. (depressurized cabin) (That confirms the oscillation/bump had to be the stairs retracting not opening) Slight pitch when stairs dropped. Obviously, higher speeds no freefall. No unusual control or handling problems should be experienced if the aft airstair should accidentally extend inflight.

FBI file 71 is up.. https://vault.fbi.gov/D-B-Cooper /d.-b.-cooper-part-71-of-71/view One big section, lots of pages is the 1964 Boeing inflight airstairs testing,, Lots of pages for this report..

All the Cooper bills were entered into National Crime Information Center (NCIC)..

Sketch "B" was the best likeness possible.. Forget sketch "A"..

Chaucer said.. "Regardless, even if he DID want the airstairs deployed in flight, that doesn't indicate he planned on a later jump. His behavior leads one to believe that he wanted off that aircraft as soon as possible." This is a half truth, first his initial demand was airstairs down inflight. But, his changing his demand based on Reno means he changed his plan. If his plan changed then the LZ wasn't necessarily where he did jump. Plus, there is the other evidence that supports a later planned jump. Before Reno was in play he rejected US airports for being too large.. He wanted a small airport.. if he was jumping in the PNW it wouldn't matter. That suggests he was still going to be on the plane. But after Reno was in play he changed his initial demand and wanted off ASAP. For a long time I thought like everyone that he demanded airstairs open on takeoff and that meant he wanted off ASAP but he was delayed slightly by the airstair problem,,, however, that turns out to be based on a false premise, that was not his initial demand. He changed his plan when Reno was in play and then he wanted off ASAP demanding airstairs down on takeoff. So, what was his planned LZ.... when he made his initial demand of airstairs lowered inflight, no stopping in US but can refuel in Mexico... Prior to Reno in play, there is no evidence to support a PNW jump.

and they had mentioned Phoenix just prior to this transmission.. so this is about the time Cooper rejected the larger US airports for refuelling, he demanded a smaller airport.. before he wanted the airstairs down for takeoff. That suggests he still expected to be on the plane when it landed to refuel.. then he changed his mind.

The crew mistakenly mentioned to Cooper that the chutes were coming from McChord. That is why Cooper mentioned the base... Most who had been in the military since WW2 would know about McChord..

Cooper's specific 727 knowledge is very mixed.. but he did know the airstairs can be lowered inflight.. either from experience or research. he would have had to be very confident those stairs would open.. no assumptions..

Another interesting exchange between the pilots and Cooper.. This is the second mention of the airstairs after Cooper was informed of the fuel range problem and they were negotiating a US airport. Cooper wanted stew to manipulate stairs after plane airborne... then pilots try to tell Cooper how to lower after takeoff (they wanted Tina off the plane).. then pilots suggest to Cooper to let them lower stairs partially for takeoff.. they don't know if they can lock partially down. That exchange seems to indicate that the pilots were the ones that initially brought up stairs lowered on takeoff when Cooper wanted lowered inflight.. It wasn't clear so the FBI (in the files) discussed asking Tina if the pilots suggested anything to Cooper but there is no answer in the files... This exchange is not conclusive but it brings up the possibility that airstairs down for takeoff may have actually been instigated by the crew, then Cooper wanted it. The crew then had to convince Cooper to takeoff with airstairs up..

Cooper said Mexico City and no stopping in the US for any reason but can refuel anywhere in Mexico. They had planned for Mazatlan. In the dirty configuration they didn't have the range.. either Cooper didn't figure out the range correctly or his configuration was miscommunicated via Tina's note.

Last time for this.. The mentions in the FBI files of airstairs down on take-off are not incorrect they just neglect to include that it wasn't his first demand. Cooper's very first demands,, first crew radio transmission.. aft stairs to be lowered after takeoff Harrison notes corroborate (time).. aft stairs lowered inflight and FBI summary.. HJ specified... the aft stairs to be extended after take-off. Later specified that stairs must be fully extended before take-off. Done.. Cooper changed his demand when they were negotiating a refuelling stop in the US.

727 flaps.. BTW,, DC-9 had 15 degree flap setting

You need to understand this case has very few 100% facts, try listing them to see, we don't even know Cooper jumped in Wa as a fact, you can cast doubt on almost anything in this case. That is why this case is so difficult and polarizing, so we use the evidence to draw inference. That is how you move a case like this along.... most of what we know about the case is by inference. The lure of the Cooper case is to use your own logic, reason, experience and historical knowledge to pull the few pieces together into a cohesive picture.. an intellectual puzzle with most of the pieces missing and some that don't belong. It may appear to not accomplish anything but it does... if Cooper changed his LZ mid hijacking then that tells us something. If Cooper's first demand was airstairs lowered inflight then his plan was not to land near Seattle as Ulis claims.

Those points are true and irrelevant to this issue, but you seem to claim without evidence that he jumped exactly where he had planned before he got on the plane. How do you know that. You don't. I have outlined actual facts and drew a conclusion by inference. You reject those facts to maintain baseless speculation. At least, you should accept those facts and draw your own conclusion... but I can't see any other one.

True,, but IMO he wasn't a mastermind but not a dummy.. He "gave no flight direction/course" can be taken as he wasn't that smart but he may have had a compass though none was ever seen. He had some airplane/flight experience.. so it wouldn't surprise me.

I am saying there is evidence to indicate his plan changed and he didn't jump where he initially intended. Not sure why that is so hard to understand. You want to stick to pure speculation that is up to you..

Not sure if we are talking about the same record of the exchange but he rejected the two airports for being too large,, smaller ones were offered and he accepted Reno. Even flying to Reno they could have gone over the water if they wanted, there really isn't that much difference. If his "plan" was to jump in the PNW it wouldn't matter which airport they chose. Apparently they had planned to refuel in Mazatlan.. There are other minor factors.. He was described as Latin/Mexican/swarthy in appearance.. Both Tina and the crew said US/American currency. He wasn't dressed for the PNW weather. and he was not concerned with the weather pre flight,, like all the other passengers. My issue is people who claim his initial demand was a ruse,, that makes no sense and has no evidence,, Cooper must have believed it because it was certain to be rejected. Why make a demand you know is impossible, would be rejected and had to be renegotiated.. There is evidence to suggest this,, the other views are pure speculation with no evidence at all.

There is evidence, if you choose to ignore it that is your problem. The evidence suggests he was going to be on the plane for the Reno refuel but decided to jump early, so South of Reno was his initial plan and probably South of the US border.. He did not jump where he initially planned, he changed his plan after Reno was in play wanted the airstairs down on takeoff and jumped early, even then he was delayed with problems opening the airstairs. His LZ was not the one he had planned when he got on the plane. If your argument is that he jumped were he had planned when he got on the plane, you are ignoring the evidence and you are the one guessing.
