(Aug 29) 1954-San Francisco International Airport (SFO) opens. It has been continually “under construction” since this date. San Francisco has had at least three airports within the city limits during the twentieth century. Crissy Field at the Presidio dates from World War I, the Marina Flying Field from 1915, and the late 1930s saw development of the Seaplane Harbor at Treasure Island. Ingleside racetrack was also used for aviation purposes in the early part of the twentieth century. Commercial and general aviation ultimately moved to Mills Field in San Mateo County in the 1930s, which originally was temporary as the originally international airport was to be built on Treasure Island..Crissy Field at the Presidio was the last airport within the city, and ended limited operations in the 1980s. http://www.leasingnews.org/archives/August_%202003/8-28-03.htm May 18 05, 1:22 AM
