The 2nd congressional hearing on UFOs/UAPs covers topics such as the ufo's defying what we know of the laws of physics, the fact that they can go up into space and come down to hang out for a while and go back into space again and that there is no evidence of anything we can identify as propulsion and appears to fly as if it can control gravity (called anti gravity device in science fiction).
Pilots have seen one shaped like a flying propane tank (also called "the tic tac") another type is a grey or dark cube inside of a clear sphere(!). There are also unconfirmed reports from eyewitnesses that there may be alien remains of some sort hidden away by the military. One thing we learn is that there is stigma against reporting encounters with UFOs by pilots on commercial airlines and there is an effort underway to make it safe and easy for pilots to report their encounters and that these encounters happen so often that there are safety issues of bumping into these UAPs. The testimony begins about 24 mins into the video:
David Grusch, whistleblower and former Defense Department employee, testified alongside former military pilots about their firsthand accounts of UFOs or UAPs (unidentified aerial phenomena). They appeared before a House Oversight and Accountability subcommittee. Topics included threats to national security, government transparency around UAPs, and reporting UAP encounters.
