Good point.
Have we ever done any serious scientific study of UFOs? I know there was Project Blue Book back in the 1960s, but I think that is all classified information.
Blue Book has been released! actually quite some time ago. You used to be able to buy a copy. What classification there was, was not due to the UFO but due to revealing the existence & capability of the “national intelligence/defense asset”.
There’s just a handful of mysterious “sightings” that are hard to explain. When I say mysterious it just means no one has come up with an explanation that fits all the supposed known “facts” of the events. The Braxton County WV Monster is still one I am happy to say!
There is a lot of upper atmosphere physical phenomena we very poorly understand & some we very rarely see. (There is just has to be the right sequence of physical events to cause it!). That’s still the way to bet until some better & more numerous facts come along.
Project Blue Book was contrived by the Air Force to be an exercise that would debunk weak UFO cases in order to ease public anxiety on the subject. Then as now the best cases were separated out and reported separately to a secret investigative unit while being publicly disparaged and denied.
