It may be true, from what I’ve seen is a few of his claims have turned out to be true...
He disclosed that some of the alien aircraft testing was done at Papoose Lake which up to that time was unknown supposedly.
I am not a chemist but supposedly he made claims about Element 115 which was not known at the time.
He could be a total nut job, but he’s interesting to watch in the interviews.
He does make a point that I agree with, if they really are testing alien spacecraft at Area 51 or somewhere else being able to reverse engineer it might be impossible for decades or more....
Think about it, if somehow we took a jet fight, nuclear reactor or modern laptop computer back to the 1750s the scientists then would have been baffled for years and years....
Just enough info to make it seem real.
BTW, I live in Nevada and follow Area 51 events casually. I have known about Papoose Lake for well over 30 years as have most serious A51 followers. There is actually a lot of local knowledge about A51, the locals just don’t share with outsiders because they don’t want to get mobbed by the groupies.
