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. An avid thinker, Davidson spent many hours analyzing major national and world events, including the Kennedy assassination, questionable Presidential elections and the Jonestown massacre. Davidson died in White Plains Hospital on January 1, 2007. His ashes are buried in White Plains, New York, He was survived by his wife, Doris, his three children (Ed, Carole, and Martha), his two granddaughters (Leah and Rachel), and his three great-grandsons (Alex, Wesley, and Nathan) and great-granddaughter (Maddie).
