Ross Field is a former World War I military airfield, located 0.8 miles (1.3 km) south-southwest of Arcadia, California.

In the early part of June 1918, the Army established an airfield at Arcadia, on the site of the Santa Anita Race Track.

In the rush to get an Army Balloon School on the west coast, the Signal Corps did not consider the Santa Ana winds, which blew in from the desert.

In order to simulate high altitude observations, they would truck the officers to a camp site at the top of Mt.

On 26 September 1918, near Brabant, France: while aloft with Lt. Herbert Hudnut, they were attacked by a German Fokker pursuit aircraft, and their balloon burst into flames.

After Lt. Ross left the basket, some burning balloon pieces dropped onto his opened parachute: he fell to his death from three thousand feet.

The airfield was apparently closed by 1940, The site of Ross Field is located southwest of the intersection of Santa Anita Avenue & Huntington Drive.
