To preface: I am strongly in the opinion that this 'phenomenon' that's being seen is most probably a US-based contractor that's been testing exotic aircraft, as opposed to any of the other possibilities. There's a documented history of that over the years, and looking at where China and Russia are at currently indicates they might not have these capabilities. However, I am going to hold off on the 'dismissing is the immediate jump to aliens' part as well, purely due to the position of this guy and the specifics of his claims - he was part of a team investigating the subject and so until he's proven unequivocally of lying I'll just assume there might be documentation he has access to that we don't. His credentials line up and it sounds as if the people who vouch for him are the same. I'll think it's silly to discredit the fact the government wants to study what's being reported in the sky like some people are doing. Beyond that I'd rather not comment because it's safer to discuss the parts we are actually privy to rather than the parts we aren't, until the dude gets charged for lying to congress or some other official discrediting of his claims.
