What became Leeds Bradford Airport was built in the late 1920s and early 1930s on 60 acres of grassland next to the old Bradford to Harrogate road. On 17 October 1931, the airport, which was interchangeably known as "Leeds and Bradford Municipal Aerodrome" or "Yeadon Aerodrome" in its early years, was officially opened. Initially, the airport was operated by the Yorkshire Aeroplane Club on behalf of Leeds and Bradford Corporations. Its early operations were typified by training and general aviation flights.
