There doesn't seem to be much discussion about this here, but Eric Ulis, Nicky B, and others have been following a line of inquiry with the tie particles (specifically a rare titanium-antimony alloy) that led them to a company call Rem-Cru which was based in Pittsburgh. Specifically, it led them to their research laboratory which reduced the number of people to only 7-8. Eric claims he has zeroed in on one man in that department in 1971 who "checks all the boxes".
Tom Kaye has signed off on Eric's logic apparently. Here are some videos of Eric explaining these developments.
I suppose part of the lack of enthusiasm comes from the fact that the story isn't finished yet - we're getting the updates in real time without the suspect name or other corroborating info at this point. Also, both Eric and NickyB have advanced other suspects in the past, so some people may be scratching their heads at this, now that they are going this direction. I'm glad they've kept their minds open.
My take: this is an awesome development.
It takes a certain level of diligence to go back to the tie evidence and review it, particle by particle. The methodology is sound here in that they are trying to narrow, as best as they can, the pieces of evidence that point to a narrow pool of suspects.
They've said it must be someone who worked at RemCru, assigned to a special group, who would have been exposed to this special "experimental" alloy. I hope they keep an open mind as they sift through further evidence, and not get too locked in to someone in that research group - i.e. could it have been an upper level manager, could it have been a guy who only worked in the group for a few weeks before being transferred, etc.
I hope they are closely documenting (or even audio recording) the conversations with the 89 year who worked with the best match suspect. If NickyB's tapes include the hijackers voice, then it would be interesting to have this person comment on the tape.
If this leads to solving the case, I'm all for them getting the credit.
