Yes, It's our old friend Cass Hough again with his favourite Thunderbolt which was written off at Bovingdon on December 20th 1943. First Lt Franklin L Robertson had taken this aeroplane on a local test flight and was about to land back at Bovingdon when the aircraft caught fire on the approach. Robertson was partly blinded but landed and ground-looped to a stop. He was removed from the cockpit in a 'dazed state' by two bystanders.
