Phantom signals on radar

An American fighter pilot flying from an English air base at the height of the Cold War was ordered to open fire on a massive UFO that lit up his radar, according to an account published by Britain's National Archives on Monday.

David Clarke, a UFO expert who has worked with the National Archives on the document release, said it was one of the most intriguing stories he had culled from the batch of files released Monday.

He said that the CIA once had a program intended to create phantom signals on radar — and that this may have been an exercise in electronic warfare. Whatever the case, Clarke argued that "there's no doubt something very unusual happened."
