Scandinavian Airlines System Flight 933 was a crash into Santa Monica Bay at 19:21 Pacific Standard Time (PST) on January 13, 1969, approximately 6 nautical miles (11 km) west of Los Angeles International Airport in California, United States. The crash of the McDonnell Douglas DC-8 Series 62, with Norwegian registry LN-MOO and named Sverre Viking, was caused by pilot error during approach to runway 07R. The pilots were so occupied with the nose gear light not turning green that they failed to keep track of their height. The aircraft had a crew of nine and thirty-six passengers; thirty people survived while fifteen perished. The flight originated at Copenhagen Airport, Denmark, and had a stop-over at Seattle–Tacoma International Airport, Washington, where there was a change of crew.
