Australian officers, blown into the air by an accidental explosion, fall in the river amid the splinters of their wrecked boat; ca. 1942
From LIFE (June 15th, 1942):
During night maneuvers in New South Wales a few weeks ago, Australian soldiers were landing at the edge of a dam when a charge of gelignite, employed to lend realism to their operation, unexpectedly exploded beneath their boat. Amid splinters and spray the Aussies were hurled into the night. As they fell, a photographer 20 feet away snapped his shutter and caught the remarkable picture opposite. The soldiers suffered only bruises and shock.
