Nick Pope used to work at the Ministry of Defence, where from 1991 to 1994 he was posted to a division where his duties included investigating UFOs. Initially sceptical, his official research and investigation convinced him that the UFO phenomenon raised important defence, national security and flight safety issues. He was particularly interested in cases where the witnesses were pilots or where UFOs were tracked on radar. Nick is now recognised as a leading authority on UFOs and the unexplained.
