by the Air Force inasmuch as commercial or military pilots are experienced in the air and are not expected to see objects which are entirely imaginative. In each of these instances, the individual who reports the sighting is thoroughly interviewed by a representative of Air Intelligence so that a complete description of the object sighted can be obtained. (3) Those sightings which are reported by pilots and for which there is additional corroboration, such as recording by radar or sighting from the ground. Commander Boyd advised that this latter classification constitutes two or three per cent of the total number of sightings, but that they are the most credible reports received and are difficult to explain. Some of these sightings are originally reported from the ground, then are observed by pilots in the air and then are picked up by radar instruments. He stated that in these instances there is no doubt that these individuals reporting the sightings actually did see something in the sky. However, he explained that these objects could still be natural phenomena and still could be recorded on radar if there was some electrical disturbance in the sky. He stated that the flying saucers are most frequently observed in areas where there is heavy air traffic, such as Washington, D.C., and New York City.

He advised that the sightings reported in the last classification have never been satisfactorily explained. He pointed out, however, that it is still possible that these objects may be a natural phenomenon or some type of atmospheric disturbance. He advised that it is not entirely impossible that the objects sighted may possibly be ships from another planet such as Mars. He advised that at the present time there is nothing to substantiate this theory but the possibility is not being overlooked. He stated that Air Intelligence is fairly certain that these objects are not ships or missiles from another nation in this world. Commander Boyd advised that intense research is being carried on presently by Air Intelligence, and at the present time when credible reportings of sightings are received, the Air Force is attempting in each instance to send up jet interceptor planes in order to
