this time zeroing in on the evidence from a 2017 scientific examination of the tie worn by the well-dressed skyjacker and left behind on the plane.
I am pretty sure he is talking about the analysis my friend did on the tie particles. It has been a long time since I watched his talk on it, but if you are interested, there it is.
ETA - The tie analysis has a lot more on it than a specific type of titanium, and Tom’s theory is that he worked for a company producing high end oscilloscopes (possibly at Tektronix), which would explain the machining particles and the rare elements used in the creation of CRT screens. (He will be the first to say that he could be easily proven wrong with more data.) The talk is kinda long and shows a lot of dead ends in their analysis of the particles, and the conclusion is “there is a lot of data, but nothing conclusive, yet”. It still is pretty neat how they exclude certain things based on small details. But I find it interesting citizen science.
He just went to the Royal Ontario Museum to zap various fossils with lasers to gleam hidden details not visible with regular light.
