The guy was ex-French Air Force. I guess his idea of a break was more aggressive.
Pretty much what the report says. Also quite the achievement to land that half-a-wing Skyraider.
"The Skyraider pilot had served initially as a fast jet pilot
and instructor in the French Air Force and, as a fast
jet pilot and instructor, he had taken part in and taught
break manoeuvres which tended to be more dynamic
than those briefed at Duxford."
