King is also a famous pilot because his girl friend, Marge Duncan (Lynn Bari) has made him the daring hero of the radio show, named after him.

A competitor named Faber (Henry Victor) wants to get the lucrative gold mine charter contract and conspires to make Charlie look bad.

The company looks likely to lose the contract from the gold mine and when Sturgeon is about to fire Charlie, King announces that he will go to Rico, Honduras and take over the charter flights.

King discovers that their charter business is being sabotaged but has a plan to fly a more direct route over the high mountains using oxygen tanks.

After seeing King make a successful test flight in his modified cargo aircraft, Faber finds out that using oxygen will give the Brady Company an advantage.

Principal photography for Charter Pilot began in July 1940 at the Twentieth Century Fox studio and backlots, Los Angeles, California.
