Fortunately, DF, we in this part of Cooper Country are the recipients of cool, onshore maritime winds, which are blowing British Columbian smoke eastwards towards the rest of Canada. Oregonian and Californian smoke is likewise being blown elsewhere.

Thank Gawd.

At last report, BC has 300 forest fires burning, while northern Cali has started its fire season with three major fires. SoCal also has a fair number of fires burning.

Here’s a question to ponder, and one that perhaps Tom Kaye would address…

How do we know that the amount and type of rare earth metals (pure titanium, cerium, strontium, etc) are unusual for that surface? Is it possible that everyone collects those types of metals in that quantity just naturally? Was there ever a control?

In other words, how do we know that Cooper’s tie is uncommon and that other men weren’t walking around with the same levels on their ties?

You're right.  We don't.  I had a discussion about this less than 48 hours ago with a friend on the phone.  Are you Mark Zuckerberg??  

Tom told a story of a Boeing engineer showing him a tie that was many years old.  Tom looked at the tie under a microscope and found it to be pretty pristine.  This is the only "control" that I've heard of.  This could be a good topic for someone to research.  What do other articles of clothing look like under a microscope?  Does a high school chemistry teacher's tie look anything like Coopers?  I would think a lawyer's tie or a doctor's tie might not, but what about someone in a shop environment?

The tie is great evidence, but what if we've put so much weight on its value just because we have such a lack of other evidence?  I agree that having "control" items might be helpful.  Even if we sample items from 2021, we could see what different industry's clothing looks like.  As I remember, the pollen on the tie sent some people on a wild goose chase to South Africa or somewhere like that.  Could the titanium and rare earth elements be doing the same?  Cooper could have hated management and used the tie as a prop. Or he could have just needed it for his costume and got hold of it somewhere along the line.

The FBI did not announce anything about the tie until around 1994 (I think).  I still wonder what might have been had they shown the tie and the tie pin to the public in 1971.

I’m not Mark Zuckerberg, but I am Edward Snowden, and I’d suggest you delete all of that Japanese squid porn from your computer immediately.

Seriously though, another thing to consider is chain of custody with the tie. I’ve heard anecdotes from people involved in the case that agents were wearing the tie as a gag at Halloween parties over the decades.

But I would like to know if other industries besides metal fabrication or metallurgy or metal research and development could be responsible for the tie particles. Could a mechanic or someone working in an auto body shop accumulate those particles? Could a high school science teacher? Could a door to door vacuum cleaner salesman?

My opinion is that the titanium is being used too frequently as a gatekeeper for suspects and perhaps that gate is too narrow or even unnecessary.

I'm not familiar enough with the microscopes used by Tom to know how difficult it is to test other items, or how costly.  I seem to remember talking to Tom once and he said if one of us could get clothing from the time period or a tie, he would look at it.  Maybe it is as simple as putting the clothing under the scope and getting a report.

The only thing I can think of that people put away in a box and save are military uniforms.  Those come off at a certain time and get hung up or boxed up.  Finding clothes from 1971, especially a tie, may be tough.  But I'd love to see what something looks like from a metals shop from today.  I think Nicky did some looking at welding.  Shutter is into all of that stuff for a career I think. He may know.  I've welded and done some basic metal fabrication and remember all the shavings.  Maybe a high school shop teacher might have something to test.

I think I sent an email to McCrone a while back, but did not hear back.  They probably have data on samples.  If they can test a Rembrant from the Gardner Museum theft, I imagine they have some control data.

I think Cooper was a blue collar worker who had some general aviation knowledge gained in the military or maybe in his job as an aviation mechanic or general laborer at the airport, but was not an aviation expert.  I think he was probably a generally normal and agreeable type of guy, smarter than the average bear, but maybe just an average performer.  Not an over achiever.   Obviously opinions of mine, and not fact.

Go to Tom's site and review how Tom found the particles with his equipment. Electron spectroscopy was central to this work. That is not something a common light microscope can do. ... You are not allowed to view links. Register or Login

I just learned a bit more about Mt Ranier via David Paulides YouTube report.  I guess 2200 years since last eruption?  I hope it stays that way.  So Mt Ranier is in WA and you are actually in Oregon correct?  Sounds like quite a place.  5 rivers and 14,000 feet.  I have never been to the area, Seattle or Portland included.  SF would be the closest I have been.   So I guess there have been a good share of people that have gone missing in Mt Ranier region.

A control? Interesting thought. If only someone had asked that and NOT been ridiculed for it by the resident troll...

Tom Kaye showed *the tie* *might* have been exposed to its odd collection of particles in an environment *like* Tek. (I think Kaye focused on Tek because it was in the PacNW, however there's an entire world filled with chemical/CRT factories).

Does anybody know if there was a "control tie" tested? Like getting an old tie from a garage sale and testing it alongside the Cooper tie for particles of...anything? Or perhaps cloth of any kind that was stored in the same environment to check for similarities?

No. No real need to. Unless you want to compare it with a tie from ??  Chernobyl?

Unsurelock: I've found that many of us have similar ideas, and although there is some disagreement on here, most of us seem to have the same end goal in mind, which is to find DB Cooper.  I agree with your old comment on finding a tie at a yard sale. I definitely don't want to claim that I'm the first or even the second person to consider testing an old tie or clothing.  Anyhow, that would be a good way to get some old clothes to test.

Hey, man. Nothing of the sort. Just commenting on how some people choose to ridicule ideas they haven't caught up to yet.

Fully aware others have looked into this first.
