A slightly light hearted reply to this thread
Just before I left the RAF I arranged a flight in a Bulldog from Abingdon (I was ground crew there with ULAS).
Because the pilot knew I had done a fair bit of flying he very kindly let me do the whole thing from engine start to landing - as we climbed out from take off the pilot was laughing and saying ''I can tell you are an engineer just because of the gentle throttle movement''
One of my earlier trips at Abingdon was in a 10 ship formation of Bulldogs (Capital Formation) - there was much coarse throttle jockeying going on which you wouldn't have liked Mr DAR
