Speed Wings (1934)

A kidnapping, three airplane crashes and several fist-fights adds speed to the plot in which the plans of a new, faster airplane motor invented by brothers Tim (Tim McCoy) and Jerry (William Bakewell) are stolen and suspicion falls on their office secretary Mary Stuart (Evalyn Knapp). But she can pilot an airplane with the best of them and she risks her life to save Tim. And when she gets kidnapped, Jerry regains his lost nerve in rescuing her.
