If true, I'm curious to know how the government even came into possession of such non-human aircraft.

E.g.

- did they shoot it down? (this seems to contradict the claims that the aircraft can perform unrealistic maneuvers like massive acceleration / extreme changes in vector)

- did some random farmer stumble upon the craft? (then why didn't the farmer post photos of it online and/or speaking out about it)

- where was it found and where is it today?

Note: I'm not saying there isn't ET. But some first principle questions seems like they need to be answered before people jump to conclusions.
