Davidson firmly believed that the objects reported to be extraterrestrial spacecraft were, in fact, experimental aircraft developed by the Air Force or CIA. On June 29, 2018, Davidson's son, Edward Davidson, found an article containing a photograph clearly showing two "saucers" in front of a hangar and surrounded by workers, two small planes and a few trucks. In the photo, the left side of the smaller "saucer" is clearly marked "USAF". The larger "saucer" has what appears to be "USAF" also but is not as clearly visible.
