On converting to the Harrier, I chose the usual high seat position, in order to see as much of the outside world as possible. When weaponeering or combat started and the HUD became more important, stooping forward was needed to see properly through it, whilst keeping the same old picture for VSTOL. After years of G like this, some of us on the squadron had a palm sized callous over the lumbar region of our spines.
Things you do for fun!
