Was just perusing the AAIB accident reports when I came accross this report. I recognised the type was one flown by Neil Williams at the time so had a read.
Although he was perhaps a little remiss for practicing aerobatics without a parachute (though he probably thought that his practice height meant that one would be useless anyway), he more than made up for it with an awesome display of airmanship to save his neck.
