There are currently congressional hearings on the topic, in which a former Air Force officer David Grusch claimed that a) the USA has had a program to try to catch UFOs for decades, and b) that they have occassionally succeeded and at least once found a non-human biological tissue.

I am asking - is this bullshit? Will we have real evidence in the next 4 months?

Whistleblower tells Congress the US is concealing ‘multi-decade’ program that captures UFOs

A former Air Force intelligence officer has testified that the U.S. is concealing a longstanding program that retrieves and reverse engineers unidentified flying objects.

The question resolves YES if there is material evidence (i.e. not eyewitness accounts), released through official channels (i.e. government agency, not whistleblowers) to the general public.

That would include:

• material probes from the craft

• biological probes or autopsy reports

• possibly actual high quality video, if it's not the usual shaky 5 pixels and actually shows something that is undoubtedly an UFO

• any other information that cannot be easily faked
