The 4602d Air Intelligence Service Squadron (AISS), based at Ent Air Force Base in Colorado Springs, was the U.S. Air Force unit responsible for field investigations of UFO reports from 1954. A claim that a Marine aviator was told in October 1954 that it ran a "crashed object" program comes from a 1955 book by British author Harold T. Wilkins and is unverified.[1][2]
The squadron
The 4602d was newly organised in 1952 under Air Defense Command, with Colonel John M. White Jr. as commander. Its wartime mission was the rapid exploitation and field analysis of downed enemy aircraft and captured enemy personnel; in peacetime it trained and prepared for that role. Air Force Regulation 200-2 of 12 August 1954 made it the organisation responsible for field investigations and preliminary reports of UFOs.[1]
UFO work
Between 12 August 1954 and 30 June 1955 the squadron received 306 preliminary UFO reports. It resolved 198 by analysis at its headquarters and 48 by follow-up investigation, and forwarded 60 to the Air Technical Intelligence Center as unresolved: 37 for insufficient data and 23 as unknowns. Its later classified Project Moon Dust tasks — recovering fallen foreign space debris and unusual objects worldwide — are documented in released records, and the National Archives' Blue Book holdings include 4602d case files from 1954 to 1956 labelled Moon Dust.[1][3][4]
The crashed-object claim
Wilkins's book Flying Saucers Uncensored (1955) relays a story that a Marine aviator was told in October 1954 that the squadron ran a program to recover crashed objects. Wilkins relayed many second-hand stories and is not considered a reliable source on his own.[2]
Legacy
The unit's genuine role in recovering foreign objects has fed speculation that it, or its successor the 1127th Field Activities Group, could have handled more unusual material. Air & Space magazine nicknamed the 4602d "the original Men in Black". There is no released record of it recovering anything non-human.[3][5]
