im not dismissing the possibility. but extraordinary claims require extraordinary evidence. the testimony of a guy who has a lot of "i heard from people involved with the project" that aliens have visited us through interdimensional travel, who has also claimed that mussolini was involved in a cover up that the pope, through back channels, alerted the US to, is simply not enough for me to take this kind of stuff seriously
pilots seeing things they cant explain is noteworthy. but saying we cant explain it is different from confidently asserting its an extraterrestrial aircraft. while they did make visual contact with an object they couldnt explain, a lot of the hype around, say, the famous tic tac stuff is what the sensors picked up (ie seeing it at 80k feet, then down to some much lower al ude, then some speed, etc), and not what was actually seen. imo its more plausible that sensors had an issue than happening to pick up an advanced alien craft.
