Just after Cedric (Bernard Fox) blows up the ammo dump with a torpedo and downs the enemy plane, he is leaning on the torpedo tube and not wearing his hat. The other men begin to cheer his having downed the enemy plane. Then the shot switches and Cedric is now standing erect and wearing his hat, and the others are still cheering, even though Cedric did not have time to put his hat or to stand up completely.
Cedric launches the torpedo off the moored boat. The torpedo shown is obviously lunched off a boat in motion because of the wake in the water.
