FLYJACK

377, Hijacker Hahneman walked down 727 Airstairs backwards and jumped back first... (FBI) also, beepers were planted and found by him.

The winds are important, the PDX data suggests it wasn't constant but shifting from ESE and that affects both the placard and Cooper's parachute drift.. The assumption has always been a universally constant wind.. pushing Cooper E of flight path.

What is interesting is that the wind was from ESE 8mph at 8 PM and changee to from the S.. What was it near Arial... at 8 PM The Placard was found directly under the flight path, it left the plane about 8:03. An ESE wind would be consistent with that.

Interesting, the "little bob" on the FDR was found later On 12/2/71.. BTW.. Latin appearance, curly hair (wavy, marceled) = Hahneman

There was a "little bob" noted on the flight data recorder, it is a magnetic foil marked by servos.. on the 727 it is located right in the Airstair cavity. The time was 8:09 which is derived from radio transmissions. IF that FDR "little bob" was the Airstairs retracting and hitting the plane after Cooper jumped then this is the probable LZ. This accounts for an error rate in flightpath and approx 8:09 jump time. It is speculation based on the assumption that the "little bob" on the FDR was made from the Airstairs banging back into the plane after Cooper left.

Based on the labels the Cooper tie was manufactured around 1965.

If you were sure and such a photo expert then you would match the tie photo's unedited and spam them all over. You haven't, you can't because it is crystal clear that Klansnic is NOT wearing the Cooper tie in that photo. The length of the rear piece is much shorter vs front piece for Cooper's tie, it is absolutely clear, not even close. and there is no way the "James Bond" of 727 Hydraulics would need a young Stew to explain how to move a simple lever to lower the rear Airstairs. That alone virtually eliminates Klansnic. IMO, of course. Would James Bond ask a grocery clerk how to operate his Walther PPK??

Robert, I checked the image of KC with his tie as well, it doesn't match either. The length of the rear piece is much shorter (vs front) on Cooper's tie. Cooper's clipon tie has a fixed length. Neither KC's nor Klansnic's tie shown in those pics match Cooper's tie. They are definitely not the Cooper tie.

Not even close. That tie is NOT the Cooper tie. It probably isn't even a clipon based on the lengths..

The length of under tie piece (back piece) on Klansnic's tie is much longer than Cooper's tie vs front piece, they are NOT the same tie. You need to check an uncropped image.

"supreme" level of knowledge is a vague and subjective term. Cooper did have aviation knowledge but evidence suggests he did not have 727 Ventral Airstair operational knowledge as a Boeing hydraulics engineer would. Hahneman threatened to fly the 727 he hijacked, he also gave specific flight instructions and indicated specific aviation knowledge, he didn't ask to be shown how to lower the rear airstairs.. My point is.. All suspects tick boxes, some more than others and some bigger than others.. Specifically which rare earth/toxic particles are you referring to.. they are all used in electronics and other environments. The Tie Particle Matrix is a reflection of the Cooper Vortex, there are many combinations of logic that can fit.. but there is only one right answer. Re: particles.. remember silicon spheres.. "Tom Kaye asked about “Barium Chloride” use… Pyrotechnics… It is used for the colour green in flares, tracers and fireworks.. maybe the "Bomb" But why on a cheap tie? and so saturated? Hand held sparklers use a pyrotechnic paste, there were many different formulas but many of the tie particles match ingredients that I have found. Some ingredients used in Sparklers.. (not complete) Iron Cobalt Potassium Barium Cadmium Lead Zinc Calcium Nickel Copper Lithium Boron Sodium Magnesium Aluminum Titanium Strontium Silver Indium Thallium Used in Pyrotechnics Yttrium (red) Silicon Phosphorus Was Cooper celebrating the 4th of July with a hand held sparkler? Asian sparklers if Cooper was in Vietnam at the time? That narrows it down to millions of people." also,, Yttrium used in production of polyester. https://patents.google.com/patent/US3523104

Just listened to Nicholas Broughton's Cooper Vortex p1 interview, he claimed that no other suspect was seen wearing a black tie. He was corrected KC was in his uniform, but Hahneman also is in a pic wearing a black tie prior to Norjak. Wearing a thin black tie in the late 60's doesn't make you Cooper, it was common though it checks one box. His smoking gun was tie particles matched tig welding fumes and no other suspect matches the tie particle environment. Hahneman was an radar tech EE, that also matches the tie particle environment. But, wearing a polyester tie in a tig welding environment sounds sketchy and there were no burn marks. He makes a logical error though, Cooper had to be shown how to operated a lever to lower the rear stairs by Tina. A James Bond like 727 hydraulics engineer with "expert" knowledge would not need to be shown how to move a lever by a young stew. Being such an expert virtually eliminates him. Cooper had aviation knowledge but not an "expert". Too much expertise is a negative not a checked box. IMO https://thecoopervortex.podbean.com

It isn't 100% that he was (ex)military but most likely based on age (mid to late 40's), the chutes he requested and he used the term "interphone". Mark's presentation on the chutes..

I try to avoid analyzing suspects because people get so offended and so far none even come close to the suspect I am researching so that is my focus right now.. but off the top of my head.. There is no evidence that Cooper worked at Boeing, in fact it is unlikely as he would have been outed with all the publicity. Hijacking a plane to Seattle where one works is unlikely. A Boeing hydraulics engineer would know how to operate the 727 rear Airstairs and Cooper did not, Tina had to show him how even then he had trouble. A Boeing hydraulics engineer not able to use the Airstairs virtually eliminates him. It is NOT inclusive. Cooper had aviation knowledge but not specific 727 knowledge. He got the range slightly short, couldn't operate the door and thought the cockpit controlled the stairs. There is no evidence that the tie particles came from Boeing. There are many sources. Claiming the tie in a pic is the same one as Cooper is more than a stretch.. Klansnic was a family man, Cooper wasn't, he was not at home on thanksgiving. Due to Cooper's age he almost certainly had military experience, that alone doesn't make him Cooper.. hundreds of thousand of males that age range had military experience. Cooper was described as swarthy, latin, Mexican in appearance with wavy/curly/marcelled hair, that does not match Klansnic, a vague resemblance to the sketch is not enough. A photo at PDX of a local Boeing employee is of no value unless it was the day of the hijacking. Airstairs lowered during flight was not a secret, it wasn't common knowledge but it was available in an Aviation Mag, newspapers, Vietnam/Thailand. Cooper was in the aviation industry. IMO, Klansnic is probably one of the weakest suspects ever presented, very few circumstantial pieces there.. a turkey neck alone doesn't cut it. Unless there are more undisclosed pieces Klansnic just doesn't register on the suspect scale. gobble, gobble. Just my opinion. Don't take it personally. I can't say it wasn't him but the same could be said for tens or maybe a hundred thousand people.

Lots of new Cooper FBI files... since this thread was closed. Usually updated monthly. https://vault.fbi.gov/D-B-Cooper

That was later, during the negotiations. NOT the initial demand.

Some FBI summaries claim Cooper initially asked for airstairs down on takeoff.. the pilot transcript clearly states otherwise. Other places confirm the transcript. It was discussed but later when the crew was negotiating to get Tina off of the plane to attempt an escape..

wolfriverjoe.. The chutes contained "burp sacks" per FBI, I assume that is a vomit bag but it may have another meaning? Ever heard the term?

Emergency airstair release..

The Placard… The placard.. I did some work on that placard a while ago.. It was found basically under the FBI flight path plotted points E of v-23 centre line. Within the variability. It is from a small plastic door for access to an emergency release which was an option on 727’s. Right of the main airstair control panel door. When accessed that small access door disconnects completely. The emergency airstair system releases the upper locks and the airstairs free fall. (if on ground) The placard was plastic or vinyl and screwed or riveted to the small plastic door. You can see the rivet/screw holes and tear away.. (maybe 5 screws/rivets) The found placard had separated from the access door. The emergency door pulls completely off the wall to access the airstair emergency release. Speculation,, Cooper was having trouble getting the airstairs down using the normal operation lever (shown to him by Tina), behind the hinged airstair control door there is a button on top to press while moving a lever. He likely then tried the emergency release. A small door to the right of the main panel, he pulled the door off and threw it out or it fell out of the plane and the placard separated from the door on the way down. That small plastic door is probably still out there in the woods. Tina.. “When she returned to the plane with the last chute, she saw he had one chute cut open and nylon cords out and he was cutting them with his pocket knife. He took the nylon cord and wrapped it around the neck of the money bag numerous times and then he wrapped it around the neck of the money bag numerous times and then he wrapped it a few times from top to bottom, and with the same piece made a loop like a handle at the top. This nylon cord was pinkish in color. He appeared irritated because they didn’t give him a knapsack for the money which he had initially requested, and after trying to put the money in an unfolded parachute, he decided to leave it in the canvas bag."

Bruce went and checked out the chute, https://themountainnewswa.net/2011/10/25/db-cooper-case-heats-up-again-with-controversy-over-parachutes/

Neither back chute had D rings.. I tried but couldn't confirm/source a "red X" on the dummy, there was an X and red flaps.. but no confirmation of a "red X". The red X came from this forum possibly conflating the X and red flaps. If Cooper tied the money bag to his body then what happened to the dummy container and chute? Why would it be missing if he used it to wrap the money but went back to the money bag? If he used the container plus the money bag, why are the contents missing? Would he throw an opened chute off the plane? or did he actually use it. Perhaps he used the money bag then wrapped it with the dummy chute and tied it to his body.. then what happened to the container? and why did the FBI agent claim to find an opened "white" chute on the plane? BTW, looking at the cut lines from the reserve, couldn't the FBI get DNA, Cooper would have to be holding the lines to cut them.

There are many errors, conflicts and opinions in the FBI files.. it is the nature of an ongoing investigation. Tina claimed Cooper tried to put the money into an unfolded parachute.. if there was no drogue was that the "missing" dummy chute or the pink reserve?

That is the problem, Cooper didn't initially demand Airstairs down on take off. If he did then it indicates he wanted to jump soon after take off. This is what everyone assumed myself included, but as more FBI files were released it is absolutely clear that his initial demand was for Tina to lower in flight. Airstairs down on take off came up later during negotiations wth crew. Looks like the back chutes had pilot chutes and the front reserves did not, but did they have a "missing" drogue chute? Different from a pilot? If Cooper wrapped the money in white material it had to be the missing drogue chute from the good reserve (if it had one) or from the dummy reserve which was completely missing. Did some digging on the chutes.. FBI NOTES P 1541PARACHUTES FURNISHED TO SUBJECT ARE DESCRIBED AS: TWO FRONT CHEST CHUTES, TWENTYFOUR FEET IN DIAMETER, ALL WHITE NYLON, MODEL T-SEVEN A, WHITE SHROUDS, ABOUT FOURTEEN FEET LONG.NUMBER ONE CONTAINER HAS “_______” WRITTEN ON IT, AND lS ABOUT TEN BY THIRTEEN INCHES, OLIVE DRAB.

HOWEVER, IT WAS OPENED WITH THE DROUGE CHUTE MISSING IN THE AIRPLANE. FBI notes P 3114EARL J. COSSEY, 349 North 101st, Seattle, advised that the pilot chutes on both of the back pack parachutes which were furnished to the hijacker on 11/24/71, were white in color. He stated that also the back pack chute which was missing from the aircraft upon its arrival at Reno, Nevada, was white in color.Concerning the chest pack parachutes, he stated that these parachutes are hand deployed and do not contain pilot chutes. The chest pack chute which was sewn up as a practice chute and which was missing from the airplane was also white in color.

Cooper initially demanded for airstairs to be lowered in flight by Tina. It is absolutely clear in the FBI files. Everyone has repeated the myth that he initially asked for airstairs down on take off and extrapolated that he must have had inside info on the 727 airstairs. The pilots were negotiating with him to get Tina off the plane so they could attempt an escape, that is when the airstairs down on takeoff came up. Pilots were trying to convince Cooper to allow Tina off the plane. So, Cooper did not have to have some inside info.. the consensus was wrong. This is from the FBI files... it is not my opinion.. Dated… 11/26/71 FBI file p 1672 "On 11/26/71 SAC CAMPBELL from Las Vegas, advised that when they entered the airplane there was an open parachute in the plane, draped over one of the seats in the the hijacker was located, which parachute was white. Examination of this parachute reveals there was no drogue chute on it. The stewardess on the plane when interviewed said that the hijacker was upset when the money was not delivered in a knapsack. As a result she saw him wrap this money in some white material. SAC CAMPBELL speculates that the money was wrapped in the chute. He advised the second parachute in the plane is a backpack, which has never been opened. It is pink and it is being taken to the National Guard in Reno at once to see if it is in workable condition." Now. the reserve chute was pink not white, did the agent actually find the dummy reserve?? would the dummy/practice reserve have a drogue? Here are images of the pink reserve chute, any indication of a drogue or pilot? https://citizensleuths.com/pink-parachute-gallery.html Tina claimed Cooper wrapped the money in white material, he may have wrapped the money bag in part of the chute to better tie it up. "“All emergency bailout rigs, such as the ones provided to DB Cooper, would have a pilot chute,” Metzler said."
