Leaves from the Log of a Sky Pilot (1915)

Joe is a young teenager growing up in a small city. While playing in their new clubhouse (inside a World War II tank at a city park), he and his friends learn that all is not well in their small community. They sneak into a hanger at a nearby airport just for the fun of it only to discover that some local folks and a member of their local police department are mixed up in drug trafficking. Not taken seriously by the FBI, they come up with a very ingenious method of using RC airplanes and other city park relics to rid their town of the bad guys.
