The last aerial dogfight on the western front of WW-II was very odd. On April 12th, 1945, two Americans were scouting in a low-flying Piper liaison plane near Berlin. That was the popular Piper Cub in its military clothing. The Americans suddenly spotted another such plane, a German Fieseler Storch below them. Neither plane was meant for combat, but the Americans opened their doors, leaned out, and began firing downward with their service revolvers. The Germans swerved and evaded. One wing touched the ground and they crashed. The Americans landed near by, captured the wounded Germans, and provided first aid. No. 2431: Fieseler Storch
