An F-35 fighter jet assigned to the 3rd Marine Aircraft Wing crashed at Marine Corps Air Station Miramar in San Diego on Friday morning, prompting an emergency response and starting a brush fire. The pilot ejected from the aircraft, and the incident is significant because it involved a high-value, advanced US military aircraft at an active Marine Corps base.

The Marine Corps described the event as an “aircraft mishap” on the flight line, occurring at about 10am local time. A base spokesperson said emergency personnel attended the scene; the available report did not state the pilot’s condition, the extent of the fire or the cause of the crash.
