There was an OC Advanced Nav Trg Sqn known widely as Gonzo, was there not, who was reputed to have used the Elsan at low level on a bumpy sort of day. He is the only person I have ever heard of who found it necessary to use same at all and the only one who suffered from Elsan turbulence as a result.
Apart from the that, the only joke about the Dominie was trying to use it for anything other than as a V bomber simulator - at which it was quite good, I suppose.
