[2] Sky Patrol is based on the comic strip Tailspin Tommy by Hal Forrest and Glenn Chaffin.

When Bainbridge (Bryant Washburn), a weapons smuggler, is aware that the Sky Patrol will disrupt his smuggling operations.

Carter is presumed dead but Tommy and Skeeter Milligan (Milburn Stone) locate a warehouse where the amphibious aircraft is hidden.

Tommy manages to set up explosives in the hold, and when the three prisoners are about to jump ship, Carter shoots a smuggler, ensuring their escape.

Principal photography for Sky Patrol took place at the Los Angeles Metropolitan Airport, from July 24 to late September 1939.
