even pilot seen the ufo?

The most convincing UFO reports were produced in the 1940s, 1950s and 1960s by airline pilots, military pilots and ex-military pilots. These men had the training and the experience to be able to distinguish between normal sky sights and highly abnormal sights. They knew what airplanes looked like, and what meteors looked like, having seen them many times. Their visual observations were frequently supported by radar data which showed essentially the same thing. They were therefore able, on many occasions, to methodically eliminate conventional phenomena from consideration when trying to identify UFOs. In those same decades, most UFO sightings were made in the daytime and frequently at close range, when shapes and surface features could be distinguished, thus making positive identification of normal sights easier and the descriptions of unusual sights more detailed. When all normal explanations had been eliminated, the witnesses could concentrate on those aspects of the experience which were most abnormal. These abnormal aspects included the shapes of UFOs and their behavior. Most of the UFOs seen in the daytime were said to have had simple geometric shapes--discs, ovals, spheres, cylinders--and surfaces that looked like metal. Such shapes are not only nonexistent among known aircraft, but contrary to all known theories of flight, in most cases offering control and performance disadvantages rather than advantages.
