Accidents and incidents On February 17, 1981, Air California (AirCal) Flight 336 (a Boeing 737-200), with 105 passengers and five crew members, was flying from San Jose, to John Wayne Airport and crashed upon initiating a go-around. The crew was cleared for a visual approach to Runway 19R while the controller had cleared a smaller plane to take off from 19R. Upon realizing that the landing aircraft might overtake the departing one, the controller ordered the flight to go around and the other aircraft to abort its takeoff, which it did. The captain of the landing Air California aircraft delayed the go-around then initiated a gear up procedure before a positive rate of climb was achieved, causing the plane to stall. The 737 then banked left at low altitude causing the left wingtip to make contact with the runway. Then the nose came down, striking the ground, and the airplane spun around and skidded down the runway before coming to rest in the margin. A fire started, but the passengers and crew exited the plane. Of the passengers, four sustained serious injuries, and 29 suffered minor injuries. The aircraft, registered N468AC, was damaged beyond repair and was written off. On December 15, 1993, a chartered IAI Westwind business jet carrying two flight crew members and three passengers (including Rich Snyder, president of In-N-Out Burger), crashed while on approach to John Wayne Airport. All five occupants were killed in the crash. The aircraft, which departed Brackett Field, 30 miles to the north in La Verne, followed a Boeing 757 for landing, became caught in the 757's wake turbulence, rolled into a deep descent, and crashed near the intersection of State Route 55 and Edinger Avenue. The crash investigation led to the FAA requirement for an adequate period between heavy aircraft and following light aircraft to allow wake turbulence to diminish. On February 13, 2017, Harrison Ford accidentally landed his Aviat Husky on taxiway C, to the left of runway 20L. A Boeing 737 was holding short of 20L on the taxiway when Ford overflew them. On June 30, 2017, a Cessna 310 twin-engine aircraft crashed short of a runway into a highway median on Interstate 405. The pilot made a mayday call shortly after taking off from John Wayne Airport and attempted to land after being cleared for emergency
