I believe the pilot concerned was on his first flight in type though had flown a Yak52 and was experienced flying the "Yorkshire Air Forces" Hurricane.As one of "Yorkshire,s finest" warbird pilots normal caution and easing gently into a low level routine on a new type was obviously not required.Eye witness reports paint a very sad story of great confidence,to which end I believe the AAIB are seeking reports in order that others might learn from this area of human fallibilty.Sadly unless really prepared and practised attempts to impress can often have the opposite effect as in this case or even more tragic outcome.
