Shy Torque, we must have been at Scampton at the same time: I was holding on the CFS Bulldog Sqn at that time. There was a barman in the Mess, called Spike I believe, who closed the bar one night and as he went through the double bend in the corridor behind the bar looked up and saw a chap in WW2 flying kit at the top of the stairs. He fled to the guardroom without stopping.
I bought some haunted airfield books around that time and spent some time looking for spooks around the place. Went to Bircham Newton esterday with Maxibon Jr on a week in Norfolk and got into the haunted squash court. Nothing there except an over-excited kid and his 7 year old son.
