The odd Air Cadet gliding school had them for aerodrome cable recovery work.
Cue horrid memories of when flying was blown off and the staff competing to see who could get the 5th reverse gear down the main runway!
Usually all went quickly to hell in a hand cart when you got crossed up changing up to 4th reverse.
I think our personal best was done by a troika of drivers. One staff seated normally operating the pedals - one staff standing facing direction of travel in the driver foot well steering with the wheel behind his bum - one staff in the passenger seat calling clutch in/out and changing gear.
Thinking about it now we could charge a fortune for this as a management bonding exercise now.
