Early in 1948 the Iowa Aeronautics Commission released a survey of aviation in the state. Conducted by a team of professors in the mechanical engineering department at the University of Iowa, the survey revealed there were about 1,000 planes used for private and business purposes in the state and there was an airplane for every 1,471 persons in Iowa. The state had about 200 airports most with turf runways. A handful of high schools offered courses in aeronautics, mail had been delivered by a flying air carrier after a severe snow storm and the highway patrol had used an airplane to observe traffic before and after a football game in Iowa City. Flying clubs were active in the state, including Flying Farmers of America.
