Continental Air Lines Flight 712, a Boeing 707-320C, N47330, on a regularly scheduled flight from Hilo, Hawaii, to the Los Angeles International Airport, California, and a Cessna 150J, N61011, collided in midair. The collision occurred at an altitude of approximately 3,950 feet over Compton, California, approximately 9 miles east-southeast of the Los Angeles International Airport. There were 87 passengers, a flightcrew of three, and six cabin attendants aboard the Boeing. There were no injuries. Two persons were on board the Cessna, a pilot-instructor and a student pilot. The instructor received serious injuries and the student received minor injuries. The Cessna was destroyed by the midair collision and subsequent ground impact. The Boeing received substantial damage to the outer right-wing panel. PROBABLE CAUSE: “The minimum opportunity for the flight crews to see and avoid the other aircraft due to the background lights behind the Cessna and the decrease in the Cessna pilot’s visual field resulting from the aircraft’s wings while turning.”
