Anyone remember a while back when Tom Kaye got into helping try to solve the DB Cooper case, after the FBI officially released the files?
Among other things, he used an XRF gun (X-Ray fluoresence spectroscopy) to analyze particles from Cooper's tie. Among other things, he found flecks of titanium- a common enough metal today, but back in 1971, that was damn near a classified military secret.
There was an open website discussing all this, though that's long since been taken down.
But, on Hackaday, it would seem there's more info, along with a possible new suspect. (Who unfortunately passed away over twenty years ago.)
(Just for my own sake, I'll say, just from that article, that I'm not so sure. The fellow shown looks like an older gent, in his 50s in the 50s, and the hijacking was twenty years later. The original description of the suspect estimated his age as the mid-forties, rather than in the mid-seventies.)
