The Roswell Incident was declassified as well. It was a weather balloon with a microphone attachment that was meant to listen to a certain layer of the atmosphere where nukes are loudest. I don’t have the link as I’m on mobile.
I don’t think the government would deny any extraterrestrial claims by the news during the cold war because it would scare the commies shitless if they thought the United States had alien technology.
Okay, I agree.
