Jeremy Corbell is annoying af and I can't stand listening to him BUT he has delivered very credible video evidence leaked to him by high level defense department individuals like Christopher Mellon. Our military (the most advanced on earth) had zero idea what the crafts were in the "go-fast", "Gimbel" etc. videos were. Once the videos were leaked, the Pentagon confirmed they were legitimate and they didn't have a conventional explanation for them. Obama, Clinton, Harry Reid, and other high level officials have also discussed the UAPs and acknowledged we have no idea what they are. Foreign governments (notably the French, Russians, and Italians) take this subject very seriously.
So I'm inclined to believe there's something there. It's not bug splatter, and it's hard for me to take anyone seriously who is so forcibly grasping at straws. A conventional explanation I will entertain is that this is all a big counterintelligence ploy by the US military to hide the ball on some sort of other technology we're developing. I don't think that is the most likely explanation, but it's plausible, unlike insulting explanations in the vein of "swamp gas".
