Captain Aero was an American flying ace who fought the Nazis and the Japanese during World War II. He was assisted by his friend Buster, members of the Sky Scouts fan club and his sidekick, Chop Suey. He flew a specialized plane that seemed to be able to use its propeller like a buzzsaw. Later, Captain Aero became a shirtless science fiction hero, flying to other planets and battling injustice throughout the solar system.
