Looks good.. Wayfarer's https://www.amazon.com/Cooper-Flight-305-Reexamining-Disappearance/dp/0764362569 "The "D. B. Cooper" case is the only unsolved act of air piracy in US history. On November 24, 1971, a polite, nondescript, and dark-complexioned man calling himself "Dan Cooper" hijacked Northwest Airlines Flight 305, Boeing 727, between Portland, Oregon, and Seattle, Washington. At Seattle International Airport, he demanded and received $200,000 and four parachutes, released the passengers, and ordered the crew to take him to Mexico. Somewhere along the way, he jumped. He was never found or identified. Forty-five years later, the FBI gave up the hunt. This book looks at the case from the perspective of a mathematician and pilot. It uses previously unexamined data and original-source documents, combined with the tools of statistics, aeronautics, and meteorology, to show where and how the FBI could resume the search and possibly find out at last who "D. B. Cooper" really was."

So, if the FDR records the magnetic heading and it was examined can't the flightpath be confirmed??

The dummy chute was grabbed by Linn Emrich,, but Cossey claimed it was grabbed in error by somebody who didn't know anything about parachute.. Cossey must be lying... Emrich would have know it was a dummy chute,, it was intentional. That dummy chute was the only one not sealed perhaps they did put a beeper in it.

Approximately $5800 determined by FBI lab... lab report not released to us.

Sioux City Sarsparilla can found in the same layer with the the TBAR money.. It started selling nationally July 1974. This was dated May 1974.

Suggests there is a NWA tape recording...

It doesn't read that way.. It says "voice recorder tape printout" and that must have come via Northwest comms. What system did they use. What tape recorder is this??

Yup, that is why it stands out and needs sorting.. Soderlind used flight recorder records... but that couldn't have been the FDR, it doesn't give those parameters. Here, it states the comm with Northwest Control Center,, could they have kept an open mic recording from Northwest?? Still need to figure out if Cooper's voice via the interphone could have been picked up.

Georger, you miss the point.. It is a printout of the recorded conversation between the crew and the Cooper.. A recording existed. The point is since a cockpit voice recorder is a microphone in the cockpit that picks up everything it might have picked up both sides of the conversation including Cooper's voice via the interphone. We know it picked up the crew side of the conversation, but unclear if it picked up Cooper. The other takeaway is that the recording would have picked up the crew and specifically Rataczak saying that Cooper "just took leave of us".. that was used early on to pinpoint the jump time. The exact timing of that statement has never been made public. Cockpit recorder is a mic in the cockpit not the FDR...

After a quick scan.. mostly news articles and posted already.. didn't see anything significant, but need to do a deeper dive.

All the other 727 hijackers survived.. Hahneman walked down the stairs backward and jumped in a back first position.. 377 believes this is how Cooper jumped. He was given a military rig from Andrews AFB..

Soderlind died in 2001. Article and interview from 2000. https://www.avweb.com/features/paul-soderlind/

Remember there was also that "little bob" at approximately 8:09 found on the FDR.. There is no doubt that the "pressure bump" felt by the crew was caused by Cooper leaving the airplane. Since the times for all the different comms were not synchronized and were rounded up or down at source, the debate is where exactly the plane was at about 8:10-8:13.. Rataczak flying the plane by hand would have known if he was over the Columbia, they knew where Portland was. In his presentation he agreed with Soderlind's analysis. In that presentation he said that they were flying unpressurized and the rate of climb/descent pressure gauge is used to measure cabin pressure when pressured to regulate and make it comfortable.. Since they were unpressurized, when the gauge goes to the extreme 10,000 ft there is a physical bump felt. Ratazcak said he got on the horn and said that, he took leave of us mark it.. << that communication is not available to us. Soderlind used this to create the early LZ.. further data supported this LZ with some very minor tweaks. Rataczak called Soderlind a genius. I believe based on crew statements that the oscillations were the movement of the needle on the gauge, not felt, the so called "pressure bump" was the extreme movement on the needle (oscillation) which was felt as a bump.. According to the crew there were minor movements (oscillations) for some time, they increased rapidly and were reported by the crew ending in an extreme needle fluctuation and bump felt by the crew.. this happens in seconds, not minutes. When the crew reported those oscillations in the cabin they were seeing a rapid increase on the gauge, the bump was the final extreme oscillation. From the crew's perspective the difference between the oscillations and pressure bump was magnitude. It was not a distinct event that occurred 7-8 minutes later. It was a rapid increase in needle fluctuation with a final extreme fluctuation and a physically felt "bump". The sled test confirmed that the gauge reacted the same as during Norjak. I don't see any evidence that puts Cooper jumping over the Columbia, only contradictory. The zone is from the Lewis R/Merwin to Battleground.

Snow is wrong,, Shutter is 100% correct.. The sled test proved that the "pressure bump" was caused by Cooper exiting the aircraft. The movie stunt is irrelevant, the conditions were not the same. Here, before the sled test they had determined from recordings that the bump was either Cooper exiting or going down the stairs. The test showed no significant pressure change when they descended the stairs. Further, We are missing a big piece that the FBI had used in their analysis.. the cockpit recording when Rataczak said he just took leave of us... For people to still claim that the FBI got it wrong or were confused with no evidence to support that claim and with less information than the FBI had at the time is just ridiculous. The FBI had various communications records, cockpit voice recordings, FDR and fresh crew memories...

This is why you are irrelevant. Just from your statement it is clear you have no comprehension of these issues. You fail to understand that when the crew noted they could see the lights of Portland that it means they knew where Portland was. You fail to understand that if Cooper ordered the pilots to fly over I5 that doesn't mean they did or were able to at all times. and you run to Shutter's site and make completely false statements.. to gain support. Why do you people always find it necessary to make false statements, are you that insecure. You people are nuts. FACT: the Sheriff's notes say the pilots were ordered to fly over I5. I never claimed they were visually following I5, YOU ARE LYING. We don't know if they were or could. FACT: Rataczak said Cooper jumped ABOUT 28 miles North of Portland that is ABOUT 8:10. Ratazcak has said elsewhere that Cooper jumped at 8:10. ABOUT 28 miles North of Portland is not even close to the Columbia River... Rataczak was flying the plane by hand, he would know the difference. Herding cats would be easier..

I got some pushback on this,, Here is what it appears,,, if Cooper ordered the pilot to fly over I5, due to conditions the pilots may not have been able to see the I5 lights all the way. North of Portland the path drifts miles East of I5 but South of Portland they were closer to I5. So, they may have been trying to follow I5 but couldn't see it the entire time.. The takeaway is that Cooper (if true) wanted to and expected to use I5 to determine his position, this is a basic aviator technique for night navigation.. Ultimately, Cooper may not have been able to see the I5 lights, we don't know.

Yes, we can,,, From Ratazcak's presentation.. Ratazcak was told that the stairs dropping would cause the nose to pitch 3 degrees,,, he was hand flying the plane at the time and confirmed that this actually happened when the stairs dropped. If the "pressure bump" occurred when the stairs dropped and the nose pitched he would have known it. So, the "pressure bump" was later and based on crew statements, comms and the sled test it is a virtual certainty that the so called "pressure bump" was caused by Cooper leaving the plane. The only question is where exactly was the plane along the flightpath at about 8:10-8:13...

Nice try, it was an estimate he said "about". I measured it 28 miles from Portland is about 8:10. Rataczak also praised the FBI calculation of the quadrangle for the drop zone.. It is over, you gave it a shot and challenging things is a good thing and part of the process but part of the process is accepting when you are wrong. There is no question or doubt about it. Rataczak supported the FBI LZ,, and since the crew saw the lights of Portland they knew where Portland was so they would have known if the "pressure bump" was over the Columbia. This is simple stuff. I have given you the evidence, if you want to ignore it that is up to you but it diminishes your credibility, some Cooper sleuths don't care about credibility.

I have the DVD of his presentation, it is about 1.5 hours long.. He said.. the exact quote. "about 28 miles North of Portland he (Cooper) jumped out of the airplane" We both know if Cooper jumped over the Columbia based on the "pressure bump" timing Rataczak would have known. The pressure bump could not have occurred over/near the Columbia based on Rataczak's statement.

Now you are just consuming your own credibility. Ridicule isn't an actual argument. This isn't difficult,, they crew noted the lights of Portland, therefore they knew where Portland was. Rataczak was manually flying the plane which turned right before Portland. He would have known if Cooper jumped over the Columbia.. He said Cooper jumped about 28 miles North. So, that is very clear. You just have no reasonable argument, none. Check Mate.

Here in the notes,, olive complexion, latin in appearance, black curly hair, normal cut, parted on left. That rules out most higher profile suspects.. Everybody has ignored this...

Donna Elliot is unreliable.. ignore that. The pilots were not taking orders from anyone other than Cooper,, they were given full authority. The notes are legit, the question is if they are accurate.

If Cooper jumped over the Columbia, the pilots would have been in the Portland glow so they would have known where they were. Why are you having such a hard time with this.. you gave it a good shot but it is time to move on... there is no evidence to support your argument. All you have is sowing doubt in contradictory evidence. If that is your strategy I can only assume your goal is not to get to the truth.. Blevins said TBAR. The plane flew over the Western side of Portland not West of Portland.

I was reviewing this video and there was a strange statement that jumped out.. This guy had the Sheriff's notes.. he read the top line on one page "ordered pilot to fly over I5" We have always been told Cooper never gave path instructions.. the path did generally follow I5, it drifted East N of Portland but followed more closely S of Portland.. Either this was an error or it is true and was held back by the FBI. It does make sense in that Cooper could potentially know where he was if he could see I5. He may have ordered the pilot over I5 with the expectation that he could determine his location. Whether he did or not is another question. from 2:45.. 4:08 "ordered pilot to fly over I5" Hard to read but the top line says... ordered pilot to fly over next line I5.

C'mon, you really think Rataczak gets it wrong by about 28 miles.. You think he didn't know where the Airport or Portland was. They saw the glow... Rataczak said he was flying the plane by hand. and they would have been very very close the Airport.. they made that turn West around the Airport and over the Western side of Portland. Ratazcak would have known exactly where he was to make that turn. Tina saw the money and held it, she confirmed "bank style bands around each package". Guys, it is 2021, not 2011, it is time to give up your old theories and accept reality, the case has moved on. You can create doubt with virtually anything but at some point the evidence becomes overwhelming.
