“By an act of Congress the United States Air Force is charged with the Air Defense of the United States. Rapid identification of anything that flies is an important part of air defense. Thus the Air Force initiated and continues the unidentified flying object program. Under this program all unidentified flying object sightings are investigated in meticulous detail by Air Force personnel and qualified scientific consultants. So far, not a single bit of material evidence of the existence of spaceships has been found.”[[XI-23]]
