I’ve checked out what they’ve said. It’s usually pretty vague, they see a lot of “something”. And unfortunately they don’t bring back proof. A couple of guys, even a couple of guys like Neil and Buzz aren’t proof just on their own, we need some stuff. Heck even other UFO people don’t believe Corso.
Could you be saying that because you know that its impossible? - Any stuff that any astronaut might find or capture would be the property of big brother, and not available to support their contentions.
