Some very interesting pictures of the cockpit of XE799 being restored.
When I saw the picture of the back panel of the front seat I was suddenly reminded of a very early lesson in the principals of flight and aerodynamics which was brought home to me time and again during my proficiency gliding course at Kinloss in 1984.
The lesson in aerodynamics was the wing having higher pressure below it with low pressure above thus producing lift.
While flying in the circuit at 35kts IIRC in the front seat (a veritable gale in an open cockpit like the MK3) my instructor would drop his guts in the rear cockpit and owing the increased pressure below the wing, the resultant guff was forced down into his foot-well and through hole in the back of my seat and then up my nostrils.
I recall it was always particularly pungent and rather unpleasant and the individual, who shall remain nameless, had the reputation of being able to clear an entire hangar with one of his trumps.
