Flying Wild (aka The East Side Kids in Flying Wild and Air Devils) is a 1941 film directed by William Beaudine under the pseudonym "William West" as the fifth installment of the East Side Kids series which eventually totaled 22 films. The film is the team's first one in the spy film genre. Plot Pals Skinny, Danny Graham, Peewee, Algy Reynolds, and Scruno all work at the Reynolds Aviation Company, which is run by Algy's father. Muggs, however, is the only one of the kids who refuses to work, although he drives the gang to work in his jalopy. Once at the aviation company, he spends his time flirting with a flight nurse named Helen Munson who is in love with her test pilot boyfriend, Tom Lawson . One day, when Tom's aircraft crashes at the plant airstrip, Reynolds suspects that the crash may have been the work of saboteurs. Later, at the airfield, Muggs jokingly appoints himself as the new operator of the flying ambulance owned by Dr. Richard Nagel and gives his pals a tour of the aircraft. Their playful games are soon brought to a halt by Nagel, the secret leader of a spy ring, who angrily orders the group off his aircraft. Mr. Reynolds, certain that spies are working at the plant, asks Danny to act as a decoy so that the spies can be identified, and has him deliver to a downtown office a fake set of plans for a new bombsight. As Reynolds predicted, Nagel's men ambush Danny on his way to the office, but the plan goes awry when the detectives sent to trail Danny lose him. Danny eventually turns up unharmed some time later. When Muggs reports to Reynolds his suspicions that Nagel is behind the espionage ring, Reynolds dismisses the accusation as a product of the boy's imagination. Not convinced by Reynolds that Nagel is innocent, Muggs and Danny begin their own investigation into Nagel, starting with a visit to the doctor on the pretext of a fake ailment. The visit turns up nothing, however, and when Danny and Muggs return to the hangar, a suspicious "accident" that was apparently meant to harm them leaves Peewee injured. While Peewee recovers at the hospital, Tom nearly loses his life when he is unable to make contact with the control tower for a landing. The controller is later found bound and gagged in
