Thats right, they exist, incontrovertably. Absolutely, positively, no doubt about it. Object that are Flying, which are Unidentified. In fact, the other day, I saw one flying over my head. It had a fuselage, and wings, and I think engines, but I was unable to identify it! Was it a 747? a 707? A new Airbus? I dont know! It was an Unidentified Flying Object to me...
Hasn't anyone noticed the obvious similarity? Wing-wash vorticies could even cause them to dance around and hover, while others move.
