They have a technique which makes them a simple and safe aerobatic. Raise the nose to a suitable angle, apply (full) aileron, a touch of rudder perhaps, wait for wings level and fly away! Without any elevator input the nose WILL be lower than on entry, and that determines the pitch attitude to be used at entry.
Well quite. Absolutely fine
if the pitch attitude at entry is correct
and the manoeuvre is flown at a safe height.
Whereas many 'victory rolls' simply weren't - with the obvious result.
I know that 'Bloggs' doesn't normally fly low level aeros, but the point was that pilots making a mess of barrel rolls was a common event - usually because of insufficient pitch at entry.
