UFO files briefing guide

The National Archives · 15 pages · text from the file's own layer

This briefing guide, written by Dr David Clarke of Sheffield Hallam University for The National Archives in March 2008 and revised through June 2012, explains the British government's involvement with UFOs from 1909 onward. It covers phantom airships, foo fighters, ghost rockets, the 1950 Flying Saucer Working Party, Air Ministry and MoD investigations, and the 1979 House of Lords debate. It also lists key National Archives file references, including the Rendlesham Forest papers, and notes that MoD found no evidence of extraterrestrial origin.

A third series of files, in DEFE 24, contains the majority of the surviving reports and
public correspondence from 1977 onwards. DEFE 24/1206 covers 1977 and DEFE
24/1207, 1977-78. These files contain papers from a number of MoD secretariats. S4
(Air) was replaced by DS8 (Defence Secretariat 8) in 1979. In turn DS8‟s UFO
responsibility passed to Secretariat (Air Staff) 2 or Sec (AS) in 1985. DEFE 24 also
contains a series of „edited copies‟ of UFO reports received by MoD, covering the years
1975-1980. These are duplicates of the main reports series, prepared at a time when the
MoD first considered the release of UFO material to the public. The identities and home
addresses of observers have been deleted from the edited reports. A MoD proposal to
make selected reports available on request to members of the public was reversed in
1984 by defence minister John Stanley on the grounds of cost (DEFE 24/1517).
