Canada again, RCAF Station MacDonald, circa 1955.
Friend over the hedge in a T-33, about to start the landing flare etc. ELECTRIC elevator trim 'ran away' full nose up, so he flung it into a 90 deg ( approx) left turn and applied power again whilst he fumbled with circuit breakers and alternate trim system with his spare hand, to get the beast under some sort of control again.
I'd have been dead.
