The Society proudly celebrated the 85th anniversary of the San Francisco International Airport. The first ten years of San Francisco International Airport (SFO) were filled with challenges and successes. Like the commercial aviation business, the development of airports evolved slowly from modest beginnings. The commitment made by the City and County of San Francisco to create its own municipal airport started with minor allocations of public funds and the cutting of the hay and grading a dirt airstrip. The airfield was officially dedicated on May 7, 1927, as Mills Field Municipal Airport of San Francisco.
