The SNJ with its starboard wing chewed off was the victim of a warm up accident on an icy ramp. The other plane involved was an F8F, which suffered even greater damage. A group of inexperienced men were being indoctrinated in the starting and warm up procedure for the F8F. The first man to be checked-out pushed the throttle forward as the engine started and the F8F broke its tie down lines. The chocks were of little use on the icy ramp and the F8F slid fifty feet into the parked SNJ.
