Well-reasoned and well-presented. Case not closed ....

Very well put. The guy has had sure things with multiple people now... maybe it is time he realizes there is no sure thing until they find bones and a shoot lol

I think you misunderstood the titanium point. The titanium found on the tie was an alloy that was never used outside that particular lab. Titanium as a metal in general was used all over the place

Watch, "Probable Cause: Dan Gryder" for the DB Cooper Facts.

Nasa Personnell Manager 1963-1974 would have those three patented products under one roof.

All very interesting. Thank you.

What skydiving experience did Vince Petersons have?

I think D.B. Cooper was the pilot that disappeared with Senator Boggs and the other congressman that went missing in Alaska.

The tie has a lot more problems than where it picked up rare metals. The bigger question is where did D. B. Cooper pick up the tie????

The wide variety of material on the tie seems to be the result of it being piled in with a lot of pieces of clothing. In other words, the man who went to this extent to have a Dynamite bomb (or cleverly built hoax device) bought his clothing for the hijacking from the Second-hand store!

No way dude case closed been following this case a long time 99% another mystery solved!!!

Johnny Utah used that same technique to catch the bad guys in Point Break

Who said Cooper was the original owner of that tie? Perhaps he grabbed it while meandering through the airport or somewhere else.

Good information...need all info before coming to finality

Who recognizes a black tie that looks like this? Surely someone has seen or worn a black tie that looks like this one where they might have worked?

The pic of Ted B. Braden was dated 1975. You wrote 1970. Nice job on the Suspect Smackdown.

Perhaps, it was a used tie he bought for his costume. Goodwill, garage sale, flea market, borrowed from his brother, friend, room mate, dad, etc. Just because these molecules were found on this tie, doesn't mean cooper was wearing it when the molecules got on the tie.
