In this entry in the "Henry Latham" series, set during WW II, an independent young woman takes control of a flying school after the owner is called for military duty. She is assisted by her father, his friend, and the mayor who were all fliers during WW I. They all have a rip-roarin' time until a bank robber hijacks the mayor's plane with the mayor in it. Trouble ensues when the plane runs out of gas and crashes. The police capture the crooks.
