I think that is true. I can remember reading somewhere that he could pull a lot more than others. I feel sorry for his aircraft though.
When I brought my Vampire back with +8 on the clock it went in for an overstress check. On the Vampire there were struts called jury struts that bridged between the main spar and fuselage. Should the wings bend too much these would indicate it. Mine were all right, that is why I was a pilot for so long.
After I had graduated the FTS was replaced by the multi engine FTS using the Vickers Varsity. Solo qualified pilots would have a junior course student as a co-pilot. One day in the bar one of these junior pilots let slip the news that he had been in a Varsity that had been barrel rolled by a senior student.
Investigations immediately started and the aircraft and date was established. An inspection of the aircraft revealed rippling along the top surface of both wings. Despite this the aircraft had been serviced and flown for nearly a month.
There were no such things as jury struts on Varsities, why? so it had to be towed to the breakers. CRM was unknown then so the co-pilot got off Scot free, I don't know what happened to the captain.
