Recently I watched a good video about green gremlins that many pilots have reported. These gremlins sit on the noses of their planes when they are flying thousands of feet in the air. Usually I would ignore such reports, but I would always make an exception for pilots. Pilots are above average professionals and are constantly exposed to medical checks etc. Plus, insurance companies require striking off pilots that report too many UFO incidents. So, pilots would be exposing themselves to a considerable career risk with such stories.
It turns out there are lots of such gremlin stories among pilots. I would say that there is a plenty of scientific evidence for UFOs. And I am wandering if UFOs can somehow remotely can create some kind of hallucinations in our heads. There are lots of reports that would match that scenrio, and I can more and more relate to what Jacque Vallee is thinking.
