Sixty Wing Commander Alan Turner, 64, who was a chief operator of the RAFs radar system for 29 years, said that all his colleagues were surprised to see 35 super-fast vessels appear on their screens. He said that the craft were equally spaced and shot from 3,000 ft to 60,000 ft at almost 300 mph. He revealed that every UFO would suddenly vanish from radar after a few seconds, and be replaced by an identical vessel moments later. <>According to him, six military radars and operators at Heathrow spotted the UFOs east of Salisbury Plain, and filed reports on the unexplained phenomenon in 1971.The RAF chief even drew a map charting their flight in between key sites like RAF Lyneham, Wilts, and the aircraft navigation transmitter at Brookmans Park, Herts.

However, staff members were instructed to never speak about the incident again, when the Ministry of Defence visited the RAF three days later. "UFOs are a fact I tracked them on military radar units. What I saw defied all logic and was, quite frankly, extraordinary. It wasn't just me," British tabloid The Sun quoted Turner, who retired from the RAF in 1995, as saying. "More than 30 pairs of eyes of RAF staff and radar operators at Heathrow Airport witnessed the same thing. Its arrogant to believe that were the only ones in this universe," he added.
