Hourglass Field

Hourglass Field was the popular name for an auxiliary landing field operated by the United States Navy before and during World War II in the northern part of San Diego, California. It is remembered as a racetrack in the regional road racing circuit and because a crackdown on unauthorized drag racing there triggered the El Cajon Boulevard Riot. A community college now occupies the site. Its athletics complex and a community park adjacent to the college are named after the airfield.

Hourglass field was located just west of U.S. Route 395 (now Interstate 15), about three miles north of what is now MCAS Miramar. It was formally known as Linda Vista Mesa Field and, later, Navy Outlying Field (NOLF) Miramar or Miramar Field / #01715 (OLF). From late 1931 to 1941 it was just a square clearing with an east-west runway. The popular name comes from the layout of the airport's runway system, which was a single piece of asphalt mostly in the shape of an hourglass (3 overlaping runways) which started construction in late 1941 and completed February 1, 1942. The hourglass field was primarily used for carrier landing practice during World War 2.

Around the time of World War II the surrounding area was used by the Navy as a bombing range. The Army also used the area as a test area.

In 1956 the Navy made the airfield available to the San Diego Junior Chamber of Commerce and the San Diego Region Sports Car Club of America (SCCA) for automobile racing. In 1957 a 1.8 mile track was laid out and the California Sport Car Club and San Diego Region SCCA staged races there for three years as part of the regional road racing circuit. The field was also used for motorcycle racing and unauthorized drag racing. In early August 1960, after three bystanders were injured during a drag race, the Navy shut down the airfield to racing. This led to an organized mass protest and a riot the night of August 20 and 21 in San Diego that the San Diego Union dubbed the drag strip riot and socialists call one of the first major youth riots of the 1960s.
