Somatogravic illusion - a grand expression to bandy around. I prefer to call it 'dis-orientation' or 'the leans', and I would be extremely cautious with ANY pilot with more than around 1000 hours who says he or she has 'never experienced it' at night, in cloud, in formation or in manoeuvre - it is a worrying thought that they might not have actually 'RECOGNISED' it. As said above, it is extremely common and a well-known aviation medicine topic.
Anyway, if we can now leave this topic for a while? Back to the thought-provoking post by JoeMo - even allowing for the fact that cameras do fore-shorten things, is the 'forward fuselage section' not too close to the tail section to fit the tail strike/break off tail/nosedive theory? Can anyone pinpoint its exact position along the 09 approach in the wreckage trail?
