Apparently Disney was in bed with the government to produce educational films for the public, including one on alien topic. The film underneath was aired once in five stations back in the nineties, and it was done only once, before it disappeared into the archives. It is a bad copy of a VHS tape, but while there is some Mickey Mouse magic, they also included some real footage.
Interesting bit is that the production company tried to publish the information many times before nineties, going all the way back to fifties and into the Project Blue Book. Maybe the reasoning behind the secrecy is that the Deep State believed we were not ready. Are we now?
