Did you read the Roswell Report (not sure of the title)?
I don’t know what was spent on it but whatever it was, it was way too much.
They’ve had multiple reports or formal positions on that so I don’t have any belief in anything they tell us about Roswell. I listened to Col Corso who claimed he had access to items not from this planet and his job was to help steer Industry to develop technology that was from parts of that. That’s why this has been hard to understand because so much is intentional BS but some is legit.
