PN: I recall reading it in Air Clues so 85 or 86 most likely.
Remember it quite well as I used to read all of the 'I learnt about...' articles and this one was rather strange.
The Jag was performing a transit and after a few hours the pilot reported a feeling 'Like I was outside the aircraft, about a wing's length behind and to the right of the aircraft. I was watching myself. The aircraft felt as though it was balanced on a knife edge and input from me into the flight controls would cause the aircraft to crash'
Perhaps not the exact words but you get the gist.
I'll see if I can google anything
