"Why did we ever think they'd come in metal ships?" -- from the Invasion of the Bodysnatchers remake.
I've watched the interview video. It will be interesting to see where this goes. Under oath, maybe he'll be able to talk intelligently about things he was denied access to? I'd be happy to be wrong, but what I see is a straightforward retelling of Majestic / Area 51. A slightly updated version is the tale of Bob Lazar, but Lazar fabricated the education that supposedly got him the Area 51 job. He's not the physicist to hire to reverse engineer a spacecraft--he was a garage inventor. The Majestic / Area 51 thing is a charming story in it's own way, but think about it, a leakproof conspiracy of at least hundreds of people (worldwide) concerning world-breaking information. I'd expect former conspiracy members to be coming out en mass if the whistleblower is telling something like the truth, because finally they are (I'd guess) free from retaliation. The "I can't prove anything and I don't have evidence to show" cant is sort of galling. It's a tell often seen in the crashed UFO mythos. So, let's posit that the whistleblower who was denied access actually knows something. Then we have HUGE PROBLEM #2: Biological aliens flying around in our atmosphere and buzzing navy ships and crashing into things? Really? After they cross light-years of space and who knows how much time with technology that we can't even imagine. Seriously, people in the extraterrestrial intelligence field do not expect living creatures to show up in metal ships. I'm an amateur, but I expect to maybe see something that we think is a radio beacon in my lifetime, but more likely the optical pulse searches could find something that looks like an intelligent signal. If we stick to a 'they come here' model, best projections for how we would do this job are very small robotic probes. Just sit in orbit and soak up all our communications. They could even get human DNA that way, or via environmental objects. No need to interact with us. People who wanted to interact with us could call us on the phone. Just put a radio signal in the Water Hole, the spectral absorption line (hence radio-quiet) of the hydroxyl molecule, at 21 centimeters / 1,40 megaHertz. I've been researching this since I read I.S. Sklovsky's "Intelligent Life in the Universe" (US Ed. with forward by Carl Sagan, at about age 10, when it was published. When a modern version of this tale pops up with approximately the credibility of a George Adamski, I don't know what to say. One way this could have some truth is if the aliens are profoundly different from anything we expect. Perhaps they would create biological robots and send them in unsafe metal ships because we'd understand that. Perhaps the real witnesses don't know what they saw and describe their best take on it. I'd love to be wrong. I've been totally excited about this field since I was a kid.
I'm triggered because a real whistleblower needs to show that they're not a Bob Lazar or George Adamski. If they don't know who those people were or why this is critically important, they don't know their field. If you want to be taken seriously don't act just like the con men.
