Ace Drummond was an aviation comic strip scripted by Eddie Rickenbacker, the celebrated World War I aviator, and illustrated by Clayton Knight (1891-1969), well-known aviation author and artist, who was the father of illustrator Hilary Knight. In its five-year run, it followed aviator Ace Drummond on his adventures around the world.
Distributed by King Features Syndicate, the comic strip ran as a Sunday page from 1935 to 1940. Rickenbacker was a key factor in the promotion of this strip through the formation of Eddie Rickenbacker's Junior Pilots Club, displaying the Ace Drummond characters on buttons distributed to listeners.
In 1936, the strip was adapted into a movie serial. The plot of which is as follows:
A mysterious villain who calls himself The Dragon is attempting to prevent International Airways from beginning service in Mongolia, in order to protect the secret of the mountain of jade for himself. It features a dungeon in the nearby monastery, the kidnapping of an archeologist who stumbles onto the secret, his daughter's attempts to rescue him with Ace's help, a death ray The Dragon uses on the airline pilots, a radio system by which The Dragon communicates with his henchmen via the rotation of Buddhist prayer wheels (each transmission concluding "The Dragon commands!"), and a squadron of his own fighter planes.
