I have previously suggested that there may have been a physiological incident as a causative factor in this accident. Definitely not proven at this point, and it may be impossible for even the AAIB to definitively pin down because about the only thing that might confirm it would be a cockpit camera focused on the pilot.
Now suppose that a physiological event was found to be a factor in this incident. How would you mitigate that?
Didn't the Red Arrows lose a pilot in 2011 for that very reason?
