Incredibly, every few seconds one of the UFOs would suddenly vanish from radar and be replaced by an identical vessel moments later.
Wing Cmdr Turner said six military radars, plus 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.
Three days later, the Ministry of Defence visited the RAF and instructed staff to “never speak about the incident again”.
Wing Cmdr Turner, who retired from the RAF in 1995, said: “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.
“More than 30 pairs of eyes of RAF staff and radar operators at Heathrow Airport witnessed the same thing.
“It’s arrogant to believe that we’re the only ones in this universe.” … – the sun
