The "ghost hunters" might like to stake out the Officers' Mess at Scampton. Especially the bar cellar area. During my time there (late 1988-9) the staff did not like going down there alone.
Also, a member of the Reds was Station Duty Officer and saw a figure in WW2 flying kit standing by the ante room fireplace, whilst doing his locking-up round around midnight. It shook him up.
I now keep 'an open mind' about such things as well after seeing something I can't easily explain and similar to the above, at the old USAAF base at Earls Colne late one night about 20 years ago.
Subsequently found out that a number of others have seen something similar there over the years
