Also interesting note, the flood of credible pentagon UFO info is being brought up by a bunch of individuals who worked in(or currently for) the US intelligence community.

These individuals are: Christoper Mellon(ex high ranking intelligence director), Luis Elizondo(Intelligence officer on and off), and currently David Grusch NGA, & NRO - the person who states that non human craft have been retrieved(OP article).
