This video shows a strong infrared return of a triangular object at high altitude which either breaks up or stops emitting heat. (You can see it at the extreme bottom of the screen. Easiest to see using full screen setting.) Migratory birds can create the illusion of UFOs on infrared films, but no migratory bird flock would disintegrate like this. This is an interesting, unusual capture. Rated B.
