Project Condign (not to be confused with the Condon Committee) was a secret unidentified flying object (UFO) study undertaken by the British Government's Defence Intelligence Staff (DIS) between 1997 and 2000.[1]
The results of Project Condign were compiled into a 400-page document titled Unidentified Aerial Phenomena in the UK Air Defence Region that drew on approximately 10,000 sightings and reports that had been gathered by the DI55, a section of the Directorate of Scientific and Technical Intelligence (DSTI) within the DIS.[1][2] It was released into the public domain on 15 May 2006 after a September 2005 Freedom of Information Act request by UFO researchers David Clarke, a lecturer at Sheffield Hallam University, and Gary Anthony, a former BUFORA astronomical consultant. The identity of the report's author/s was not made public.[1][2]
