Lister,
Sorry not to see your smiling mug around today.
As has already been mentioned, it's not just the flying of the a/c one has to worry about - there's the question of manouvering on the ground. I vividly remember sharing the cockpit of a Canberra T4 on the ground in high winds before the rudder and aileron locks were inserted by the ground crew ... it took the combined effort of the pilot and myself to restrain the control column and rudder bar to stop them thrashing us and breaking bones. Trundling around with the wind coming from all quarters could be mighty 'entertaining'
