Sky Patrol (1939)

One of the "Tailspin Tommy" series of movies starring John Trent. In this movie he is training young fliers to do border patrol work looking for smugglers. Carter Meade (Jackie Coogan), whose father is in charge of the operation, has a fear of firing guns, and his father is determined that he will overcome it. Tommy sends him out on patrol, on orders from Washington D. C., to stop any unfamiliar aircraft. Carter challenges an unmarked amphibian plane, which opens fire on him. Carter, afraid to shoot, bails out as his plane is shot down. Carter is missing, and Tommy and Skeeter are searching for him and the mysterious airplane.

Marjorie Reynolds provides the romantic interest. Milburn Stone (Doc on the TV Gunsmoke series) is Tommy's partner.
