@Existential - I'll tell you where I am personally with the Lazar thing and thus why I even brought him up at all.. Firstly I am far from a confirmed nuts n bolts/ETH guy and in no way shape or form a 'true believer', but there is an aspect to the whole Lazar case which I definitely think worthy of mention.
The whole Lazar story is the same as 99% of Ufology in general, utterly lacking in tangible, hard evidence and ultimately probably forever unprovable. For a moment, forget completely every claim about aliens and back-engineering a UFO. I want to draw attention to the fact that during the frenzy of the early 90's about the Lazar-Area 51 claims, different people attempted to check Lazars education and employment history to at least verify the parts of his claims that could be verified, namely, where we studied and where he worked, positions that one could argue would at least put him in the running for
maybe being head-hunted for a super-classified black project. George Knapp, Stan Friedman and others were puzzled that not only did they not seem to be able to verify where he got his undergrad. degree, neither could they verify that he had worked at Los Alamos Labs at all; Knapp did find his name in the lab phone directory and a newspaper story about him but as for actual evidence of employment, he hit a brick wall.
It proved impossible to check most of his past, which was strange in itself. For me the interesting point is that if Lazar was making the whole thing up but had indeed worked at Los Alamos, there would be no reason to erase his work history and deny that he had worked there but for years and years, the Lab pointedly said he had never worked there. Fast forward more than 20 years and it comes to light from a credible source still working on classified science projects for numerous secret labs, including Los Alamos, that Lazar had worked there as a physicist and that he was very well known generally too.
It begs the question why does it seem that a lot of work went into erasing Lazars past if he was just selling fantasies to whoever would listen? I haven't got a clue as to whether his claims have any validity, I only point out that it now seems he was officially erased from the labs history - so why? I think this is very worthy of discussion, if others feel differently, cool, I'm not trying to convince anyone...
I've actually thought about getting some good books and re-teaching myself geometry, trigonometry and algebra. Could be fun, instead of playing Sudoku or something, but shit, I digress. )
