The raid itself, using specially modified Lancaster bombers, was judged to be only a partial success but the bravery of the crews cannot be questioned. One such crew was aboard Lancaster ED925. Piloted by Flt Lt J. V. Hopgood, the aircraft was hit by AA fire on the outbound journey injuring the wireless operator and front gunner. Despite this Hopgood continued to the Mohne Dam but released his bomb too late, destroying a power plant at the foot of the dam. As he climbed over the dam his aircraft was hit again, setting an engine ablaze. Three crew members escaped the crippled aircraft before it crashed 6km from the dam.
