Mickey Postier Du Ciel

Mickey the mail pilot is entrusted with a chest of money. He battles rain and snow, but his biggest battle is against Pete, who has a plane equipped with a machine gun and a harpoon cannon. Mickey's plane quickly loses its wings and propeller to Pete's armaments, but he improvises a helicopter blade with a clothes-drying rack, then, when that gives way, a replacement prop from a windmill.
