Very indirectly, 'PI was one of the two Tridents which had the tail scythed off by the crashing BKS Ambassador at Heathrow. Unlike the other one, it was repaired in a major job. Between that and Staines it was in a Heathrow hangar having a check when a Comet on engine test close outside had the wrong chocks applied, overrode them, and lunged forward bringing the hangar doors down on the tail. Repaired again, an extraordinarily unlucky aircraft. I believe in the first days after Staines there was much checking of records to see if a mechanical failure from the repairs might have happened.
