Peter Phillips
Yes Peter had an accident in South Africa at Airshow Africa 1977 in a BN Trislander.
He and the other person on board survived but the aircraft was destroyed.
Classic case of underestimating the impact or altitude and temperature on performance in what was/is under-powered at best.
The strength of the airframe was demosntrated after such an impact and Peter was left with only flaps and tim tabs. All other control surfaces were locked after the impact.
