So, I listened to the Bob Lazar JRE-episode last night. Then, found the documentary on Netflix. So, this story has now consumed 4 hours of my life. Here is my take.
In his Favor
Bob Lazar comes across as a non-attention seeking and truthful person. He doesn't seem to make sensational claims (outside of the base-claim, which is pretty sensational). He stays within he realm of expertise and what he says to have seen. He doesn't ever claim larger conspiracies.
His most compelling argument comes in the form of knowing what element 115 and the hand-scanners where, decades before they became public knowledge. A lot of the stuff he claimed has since been revealed to be true. If he has a bunch of bullshit as well, it was not presented in the documentary or brought up in the podcast.
There has been a severe reaction to him by the authorities. He has been targeted, black balled, his past has largely been erased, friends and family have been persecuted to varying degrees. Why would any effort be put into someone that was just simply a lunatic?
An Argument against Him
I can "mostly" buy that he came forward for reasons of self-protection and preservation, rather than fame or fortune. But, still that does not explain why over 20 years later, he is willingly digging up the past and putting himself back in the spotlight once again.
His background and resume are pretty suspect. Even if he did get his schooling credentials wiped off the record, why would they hire someone off the street and day 1 show them the biggest secret and proof of conspiracy in human history? People in these positions come up in the military and government agencies because they have time to get sucked into the culture of secrecy and develop trust. Bob was just a smart guy that built his own rocket bikes on the weekend.
From what I can tell, the scientific community is pretty against him. The best show of support he can seem to muster is a "shrug of the shoulders and a 'maybe' " Nobody from the same plant has ever come forward to substantiate any of his claims. No friends, no coworkers, no pilots, nobody. He is something between an outcast Pariah and a ghost to them.
His documentarian is definitely an attention seeking douche that no doubt would sensationalize things for fame & fortune. He has the intense confidence of a straight up shyster.
Verdict
90% chance this is bullshit. I think Bob is a very intelligent person that was involved in some military research. He probably got himself into some shit and made these claims as a cover-up/re-direct story for something he could have really gotten in trouble for.
