I was, apparently, reported as an UFO to Newcastle Airport on the evening of April 28 (NOT 1st) 1966 whilst on a night navigation sortie in Jet Promise Mk 4 XR 666 from 6 FTS at RAF Acklington.
I had to provide a report as to the exact details of the flight; what I had seen that was unusual (nothing) and any unusual occurrences during the flight (nil).
Never heard anything else about it.
