FLYJACK

I had noticed that there are horizontal lines of concentrated particles on the tie under UV.. At first I thought they were smears as if an object was wiped across the tie which would be odd. However, now I think those smears of particles are from the tie clip... the tie was folded over in storage in different ways over the years.. As it was removed it was put back slightly differently.. In other words,, those lines of concentrated particles are from contact with the clasp when the tie was folded up in storage. The take away... samples were taken from those areas and the particle concentration would be transfer from the tie clasp. and the clasp was on the right.. (the left side was an error)

I was looking at one area/sheet in the file with a concentration of AlMg.. most there do not have a third element and the others are inconsistent. That tells me either McCrone is a bit sketchy or they just aren't alloys.

and Cooper may not have even worn the tie when the particles were deposited.. I found a 100% gold particle... does that mean he was also a gold miner. The particles can be from the plane, from handling or storage post Norjak from fingerprint processing,, plus the life of the tie from about 1965 to 1971... Since the particles are on the backside.. they were deposited from the hands or while not worn. The particles generally fit pyrotechnics, dentistry, electronics and other environments. OR a combination of environments.

I doubled checked the Al Mg particles... Problem,, most show no third element.. and all the registered alloys have trace elements So, either McCrone isn't that accurate for trace elements OR those Al Mg particles are not registered alloys..

How accurate is the McCrone process for the trace stuff on the particles..

It doesn't fit any registered alloy perfectly... at least the vast majority of particles I identified previously. The Mg was about 4.5% and trace elements varied but most contained Ni. My hunch is the source wasn't a registered alloy but I need to go back and check all the AlMg particles...

Try to find Al Mg 4.5-5% with trace Ni... It doesn't have to be a registered alloy..

That is jurisdictional registration not invention... it can exist prior. It says 5056A was redesignated 5019 (in 1972) But the tie particles had Ni as the third element. The only one shown with Ni is 5283.. registered after Norjak. and that is not correct.. powdered magnalium can be in 5% Mg.. though it can range. It is in the post.. Powdered magnalium Al 95 Mg 5 https://www.nanochemazone.com/product/magnalium-powder/ Magnalium is a general term for aluminum with magnesium.. the ratio can range but the most common is mg 5%..

For decades the dominant narrative was that Cooper demanded airstairs down on takeoff,, that led to the reasonable conclusion that he wanted to jump ASAP. But since Cooper's initial demand was actually airstairs lowered in flight.. That changes things.. and we can explore other theories. Cooper never gave flight path instructions.. he may have intended to do that in the air. Cooper didn't jump where he initially planned.. he likely intended to jump more South. Cooper believed the plane could make Mexico.. he may have wanted the plane to fly gear down flaps down when the stairs were lowered inflight.

I posted about those ALMG5 particles a year ago,,, It is Aluminum alloy 5019.. or Magnalium which is commonly Ti 95% Mg 5% but the ratio can vary. https://www.makeitfrom.com/material-properties/5019-AlMg5-3.3555-A95019-Aluminum https://procure-net.com/product/aluminum-alloy-5019-wire-8/ Industries and Applications: Beyond its raw strength and durability, the Aluminum Alloy 5019 Wire is also versatile, finding its application across several industries: Aerospace: Frequently used in aircraft structures, including frames, panels, connectors offering lightweight and durable solutions.

Timeline.. FIRST Transmission of demands. 6:21 PST (before) Pass loading door open and airstairs lowered after takeoff 6:15 PST (18:15 CST ) Aft door open and aft stairs lowered inflight. CONFIRMS ABOVE TRANSMISSION 6:38 PST (before) Wants girl to manipulate stairs after airborne Have tried to tell him (how) to operate stairs to lowered after takeoff Trying to get him to let us lower stairs partially for takeoff (The crew may have initiated stairs lowered on takeoff as they were trying to get Tina off the plane, it isn't clear) 6:35 PST Wants one girl to lower stairs. (Cooper still wants lowered in flight) Soderlind wants stairs locked at takeoff.. responding to above crew suggestion to partially lower/lock, 6:59 PST (before) Cooper still wants Tina to stay. Insists stairs in 1 deg.. (That may mean airstairs unlocked OR they mixed up AFT DOOR open with AFT STAIRS open) Still wants girl to initiate lowering of stairs. This doesn't make sense if Cooper wanted the stairs down on takeoff. 7:05 (before) Advised Cooper.. can't takeoff with door down 7:22 (before) Has agreed to takeoff with stairs in full upright position. 100% fact.. Cooper's initial demand was airstairs lowered in flight.. The crew first suggested stairs partially open to get Tina off the plane. It isn't clear what Cooper actually wanted, either Cooper agreed to have the stairs partially open for takeoff then the crew had to convince him have them closed OR the communication between Cooper and the crew via Tina conflated the "open aft door" and the "open aft stairs".. The crew may have misunderstood Cooper's demands passing through TIna.. perhaps Cooper was insisting the aft (bulkhead) door open and the message going through Tina was received as aft stair open. it isn't clear as we only have what the crew believed. But, this is supported by the fact that he still wanted Tina to lower the stairs and that doesn't make sense if Cooper wanted the stairs down on takeoff.

Aft entry door.. "open" is the rear bulkhead door.. I think that is part of the confusion over the years,, the rear door vs airstairs.

I find it a bit disturbing that long time researchers still can't acknowledge basic evidence.. If you check the comm sequence, it is clear. Cooper initially demanded airstairs lowered inflight. then when Reno was in play lowered on takeoff. then he finally accepted lowered inflight. This FBI document confirms it. There is no wiggle room.

No it wasn't, it was the very first transmission of the demands.. later they discuss airstairs lowered for takeoff. Look for yourself. The Harrison notes confirm it, the FBI files confirm that Cooper initially demanded lowered in flight.. then changed to lowered on takeoff when Reno was negotiated. It is indisputable and a big deal that most people continue to get wrong.

This is a myth that has gone on forever.. and created false theories. Cooper's initial demand was airstairs lowered inflight.. later, when Reno was in play during negotiations airstairs lowered on takeoff came up. I have gone over this many times, it is 100% proven in documents that his initial demand was airstairs lowered inflight. It says so right in the crew transcript of his initial demands you just read above and claimed the contrary. "AFT STAIRS TO BE LWD AFTER TKOFF"

You already said it was all wrong but can't point to a single error. Why, because it contradicts your WFP theory.. We can calculate the NM travelled along the path. We can calculate ground speed based on times. We can compare ground speed to known reported airspeed. We can derive the average wind speed. and we can determine that the plane can't be at 23 DME PDX at/before 20:18, it would have to have travelled too fast.

Yes, it isn't 100% proof but the totality of evidence suggests right handed. Also. cig stains on right hand,, 85% are right handed.. Point is there is no evidence to indicate left handed. and Cooper must have believed the plane could reach Mexico otherwise he would not have made a demand he knew was impossible and would have been rejected.. therefore, it is likely a comms error via Tina relaying the message to the crew. Perhaps he initially wanted flaps down gear down later when stairs were lowered inflight. That changed when Reno was in play... This is the best info for Cooper's initial demand.. The crew's comm's.. First, Cooper wanted airstairs lowered inflight. Initial demand. and the the gear down flaps down is vague... did he want to fly all the way dirty or later when stairs are lowered.. The crew/Tina assumed fly dirty from take off... but he may not have meant that. That assumption, if wrong would mean Cooper's demand to fly to Mexico was achievable and it makes sense. Remember, the demands went through Tina to the crew.

R99 has not responded so I guess he realized he was wrong. I checked with a friend who is a current commercial pilot and he said it is correct, the only additional comment was the curvature of the earth but that is insignificant over short distances. What does it indicate,, For the 10 minutes between 20:05 and 20:15, The ground speed was 188.52 nm, the plane slowed down to about 150 k airspeed. If we assume the average speed in this section was slightly higher at 155 that means Cooper jumped into a 33 knot South wind... Cooper's wind drift would have been about 33 knots toward North at exit,, the variables are time under canopy and wind at lower altitudes. Spangler calculated a drift zone using wind estimates and without transcripts.. IMO, this data indicates Cooper's drift was more Northerly up to 5 nm..

Cooper sat on the right to have the bomb on his right controlled by his dominant hand. He carried the case flat with his right hand,, You carry a case with your dominant hand. It isn't 100% that he was right handed but all evidence supports it, ZERO evidence supports left handed.

Nope, No evidence for that. Evidence is against. He changed his plan.. then he was delayed and never gave any location instructions.. He landed in an unplanned area and would not have had an escape plan for it.

A common question is why did Cooper choose 305 from Portland to Seattle.. I don't believe Cooper was local so there is that caveat. IMO, flight 305 was a good choice for the following... a short flight. a light passenger load. A full plane is harder to manage. a location he was familiar with/had been there before. a flight to a major city with easier access to ransom money. a flight to a location within an hour of a major AFB to obtain parachutes. Front and back chutes is military speak.. Major US AFB bases..

Does anybody know about the use of ties in the military after about 1965... Were they strictly regulated? I have read that some used clipons and even bought their own,,, might depend on branch.. and rank.. job. (obviously not combat soldiers) Could Cooper's Penny's Towncraft clipon have been used in a military environment?? https://www.usmilitariaforum.com/forums/index.php?/topic/83572-clip-on-tie/

So, the alligator clip can only grab a man's shirt from the right side.. Whether the wearer is right or left handed. Further, there are two pin holes in the tie, one is very significant meaning that for the life of the tie pre-Norjak, it had a pin. Since you don't wear a pin and a clip that suggests the clip was put on for the hijacking and the pin was removed. Also, if you have a tie with an obvious pin hole you keep using the same hole to hide the damage to the tie, you don't switch to a clasp leaving the significant pin hole damage exposed. Why remove the pin and use the clip for the hijacking.. if it was a company/agency pin you would remove it OR the tie was not worn by Cooper pre-Norjak and the tie was obtained for the hijacking with the pin removed. So, Cooper's tie from about 1965-1971 had a pin, either a company/agency pin and was replaced with the MOP alligator clip for the hijacking. If Cooper owned the tie he removed the pin OR Cooper obtained the tie for the hijacking and added the alligator clip. Further, with an alligator clip it is easier to remove the tie and replace and more robust for a jump. An alligator clip is a better option for a hijacking.

Why ask then? Point is we have enough trouble sorting out evidence, some dummy sticks the clasp on the wrong side of the tie and so it gets used over and over as "false" evidence that Cooper was left handed..

Try Google before you embarrass yourself.
