Mick,
I Just listened to the latest Joe Rogan Podcast with Neil DeGrasse Tysson (#1658). They discuss "UFO's". I think one of the most misleading thoughts out there is that pilots are "Trained Observers". Why do we treat pilots as quasi experts on UFO sightings? I am a captain at Southwest Airlines and I can not tell you how many pilots have no clue what they are observing in the night sky. I have so many stories in this regard. In fact I would say most airline/military pilots are shot gun loaded to report a UFO with some interesting language to describe what they are seeing. Things that I have personally heard pilots report as a "UFO" on ATC frequency .... a cluster of mylar balloons tied together and floating through airspace, weather balloons at high altiutde (These things expand to 30' to 100' ft in diamteter at high altitude), Starlink satellites, Missle or rocket trails in the early morning or evening (They can look very mysterious in the sky during those hours), drones (quad copters). Lets out it this way, I know about a captain at American Airlines who is no shit a "Flat Earther". I am not kidding. Pilots are no better than the general population, in my opinion. The only Pilots who are capable of identifying or questioning what they are seeing in the sky are those of us who are alo skeptical or knowledgeable about the night sky, and what we are looking at. I cringe everytime I here a UFO story and the person relating the story says, "Well this was seen by a navy pilot, or an airline pilot." Like this group is qualified to be an expert somehow.... uggghhh
