I have not seen the full report, but how do you get yttrium on Sheridan? Even if Boeing had color CRTs, they are vacuum sealed and have no external phosphors. He was not working where tubes might be broken. Broken tubes have toxics and glass shards. They wouldn’t just be casually tossed in scrap bins. Sheridan had ALL the skills but I don’t see how he got ALL the tie elements. Scrap bins might have titanium, aluminum and bismuth but yttrium seems a real stretch.

Yes yttrium was used in cathode ray tubes as well as an additive for titanium and aluminum. It was also used in color TVs and radar hardware. Simply put, it was and is everywhere, including Boeing and at home. Regarding how a trace of it ended up on his tie, I don’t know. That said, it is very easy to put Sheridan and yttrium in the same room at the same time. E

How can you be so certain that the FBI didn't eliminate Sheridan Peterson as a viable suspect based on DNA tests? Silence doesn't necessarily mean it was a possible match. They did announce results on Duane Weber and LD Cooper DNA tests, but those were high publicity cases. When Sheridan was tested there was little or no press interest in him.

Your position that the FBI never cleared Sheridan on DNA is in dispute. Sheridan says in his July 2007 Smoke Jumper magazine article: "Several days later, one of the agents paid me a second visit. She assured me that there were no matches for my DNA."

I know Sheridan Peterson. He told me some wild tales about sport jumping in Vietnam during the war, something that I initially suspected was exaggerated or even made up. A friend who served in the RVN Army as a paratrooper and also made skydives with the Saigon Sport Parachute Club verified every last detail of Sheridan's account including DZ location, aircraft used and anecdotes about the clubs tyrannical leader Duffy. His stories about being in Beijing and witnessing the Tiananmen Square massacre were also met by some skepticism on my part but it later checked out through independent sources. In short, I have found him to be truthful. How can you be so sure he is not truthful about the FBI clearing him on DNA?

This is from the above referenced Smoke Jumper article authored by Sheridan: " Soon after the 1971 heist, agents visited his mother [Sheridan's ex] at her high school counseling office in Bakersfield, Calif. They wanted to know where her ex-spouse was; she said she had no idea.“Could he have been D.B. Cooper?” they asked. “Yes, that sounded like something he’d do,” she said.

Bitter ex trying to nail Sheridan or an accurate observation of his character?

Sheridan has no prior criminal record. He passed DOD and DOE security investigations for program clearances. Honorably discharged Marine, WW 2 vet. USFS Smoke Jumper. Civil rights worker in the South during the 1960s. Public School teacher. Hardly a shifty grifty background.

Do you have verifiable proof for items 6 & 7? I learned a long time ago that just because someone says it, doesn't make it true, especially when it comes to D.B. Cooper suspects. The web site looks good though.

I spoke multiple times with Mary Jean Fryar about Sheridan’s claims, and Bruce Smith’s claims, of negative DNA results. She verified that she DID NOT say that the FBI’s DNA analysis cleared Sheridan. She stated that once the DNA was taken it was sent in to be processed. At that point it is “RUC”—returned up on completion—thereby closing the task on her end. This means her job is done and that she is unlikely to receive any information about the results—by the way, which often take weeks or months to process. Therefore, she can’t even verify that his DNA was tested. I believe there simply was some miscommunication that led to Sheridan’s and Bruce’s claims.

That said, I investigated and determined that the FBI had in fact NOT publicly cleared Sheridan by virtue of his DNA test as they had done with both Weber and LD Cooper. So, I gave them a chance by reaching out to Ayn Dietrich-Williams and specifically asking about clearing him as had been done previously, therefore establishing a precedent. Dietrich-Williams responded by stating “out of respect for the privacy of individuals, the FBI does not typically comment on subjects in the NORJACK investigation.” It stands to reason, if the FBI had previously cleared Sheridan they would have reiterated that fact. Furthermore, it stands to reason if the DNA did clear Sheridan that they would have taken the opportunity to do that as well.

Not to put too fine a point on it but consider this: Sheridan’s DNA was submitted in 2003, Larry Carr, the former point agent on the NORJACK case, as you well know, actually struck up a brief correspondence with Sheridan and purchased his book several years later—approximately 2010. Why would Carr do this if the DNA had cleared Sheridan years earlier? The implication is that at a minimum the test wasn’t processed. However, this seems highly unlikely especially when you consider that the FBI actually investigated Sheridan’s time in Deer Park, Washington and Nepal—no easy task.

None of this is proof that the DNA was processed or that it came back as a hit. However, in totality, the implication is suspect and I have proven that the FBI hasn’t cleared Sheridan publicly and that the FBI has remained remarkably silent regarding Sheridan for some reason.

Without getting into specifics here, the context of the proof is significant. It is important to remember that unlike many other Cooper suspects, Sheridan has not claimed to be Cooper. In fact, he has been very coy when asked directly about being Cooper whether by me or the FBI. It helps to know the man and his mannerisms which I do get into in the report.

Thanks for posting 377.  Great article, written by Peterson himself.  The below is a passage that stuck with me:

“Absolutely,” I said. “First of all, I’d have known which
chute and reserve to take. Besides,” I added, “I would have had
an altimeter and a stopwatch and had an approximate idea of
the elevation of the terrain.
“I would also have insisted upon a helmet and have been
wearing boots and warm clothing. And above all I’d have
gloves, warm gloves. What’s more, I’d have needed a flashlight
to spot my landing."

By his own admission on the History Channel special, "everything pointed to me, everything."

But getting to know Sheridan doesn't reveal a sociopath, quite the contrary. He cares very deeply about people, especially those he views as victims of a system he sees as uncaring, cruel, racist, warmongering and elitist. He saw a friend reduced to a pile of smoldering ashes by a white phosphorous bombing attack in Vietnam. Might that engender a grudge? Of course.

Can I see him credibly threatening to blow up innocent NWA 727 crew members just for money? Nope. Could I be fooled? Sure, but having dealt with many criminals in my years as a defense lawyer, including some very intelligent and clever ones, Sheridan just doesn't fit the mold. None of them cared about less fortunate people. It was all about them. It was all about "getting over on someone", "pulling it off", "sticking it to the man". Sheridan has never come across like those people. If you look at NORJACK as a political crime, however, then maybe the common criminal stereotypes are irrelevant.

FBI SA Mary Jean Fryar found him fascinating. She's right. My wife agrees also. He is a deep thinker, complex and a bit mysterious. He is a highly skilled parachutist and absolutely fearless about trying risky variations and alternatives to standard jump practices. The gear he jumped in China was appalling, no cutaway releases and questionable construction quality. His bat wings were dangerous as hell. Many prior experimenters died. He'd jump right now at age 92 if a DZ would allow it.

In my opinion, Cooper DID pick the right chute. Was it a reasoned choice or just a 50-50 random pick? We don't know. But a mil spec C-9 is way better than any commercial canopy of the day, especially for a high speed deployment. That's what I would have selected.

I’ve been saying from day 1 “ I’ve never gone on a hunting trip without a compass and an altimiter”.It goes without saying a flashlight is a must ! However what so many are overlooking is he also brought along a bag ! Why? What was in the bag? I carried my altimiter and compass in my pocket so i could constantly check the direction and elevation I was hunting in. It’s absurd to think he carried this bag along with nothing in it ! I always carried a back pack with an extra clip for my rifle, small flashlight, extra pair of wool socks,wool gloves and perhaps some jerky etc. Those items are all small and necessary if you get wet ! Let’s stop forgetting about his extra bag that is documented by everyone on plane.

I investigated the bag heavily. As is typical with this case there was some variance in the descriptions: light yellow, pink, paper, canvas, etc.

The one thing that strikes me as odd is that there apparently wasn't anything printed on the bag. In other words, an odd-sized plain bag. I was hoping to attribute it to a certain region, ideally Nepal, but ultimately was unsuccessful. One thing seems likely though; something was in the bag.
Some men see things as they are, and ask why? I dream of things that never were, and ask why not?
