Whilst we are on the subject, and apologies for the slight thread drift, I was thinking of turbulence and how it acted on an aircraft a lot yesterday morning.
At the time, I was failing to sleep on a 744 due to the fact that the world was bouncing around like an out-of-balance washing machine at FL340 so naturally my sleep-deprived brain started to think about physics.
I was trying to answer my mental question of "Where should I sit to minimise the movement caused by this". I was close to the nose and wondered if there might be a significant pitch component as well as the general up-and-down motion. My instinctive answer was that the minimum effect of the turbulence would be at the centre of lift - but then you have the problem of the moving air mass doing different things at different places in something the size of a 744.
Anyone with better aeronautical credentials than me care to comment? Was the correct answer to have another drink and ignore the infernal shaking?
