Danial, Hi Compared with the number of pilots who want to/do aerobatics that list is a drop in the ocean. Flying over the sea, unless you have a pretty good horizon, is far more difficult and demanding as it's only too easy to get disorientated if you're rotating at 300 degrees/second. The Harrier pilot knew exactly where his aeroplane was going to end up as he had inadvertently moved the throttle away from the firewall!
