Western Air Lines Flight 636 was a scheduled flight between Los Angeles International Airport and Oakland Municipal Airport in Oakland, California, with an intermediate stop at San Francisco International Airport. Late in the evening of April 20, 1953, the Douglas DC-6B aircraft serving the flight crashed into the San Francisco Bay while making the short flight from San Francisco to Oakland, killing eight of the ten occupants of the plane. Most of the aircraft and two of the victims were never recovered from the bay. An investigation led by the Civil Aeronautics Board (CAB) concluded that the pilot had made errors during the flight while trying to remain below the low cloud cover. The errors resulted in the aircraft descending below the minimum safe altitude and eventually hitting the water. The flight crew may have experienced sensory illusions while flying in the darkness with only the distant lights of the airport ahead to use as a visual reference. This may have led the pilot to believe the aircraft was flying higher than it actually was.

Air Canada Flight 759
Air Canada Flight 759

On July 7, 2017, an Airbus A320-211 operating as Air Canada Flight 759 was nearly involved in an accident at San Francisco International Airport in San Mateo County, California, United States. The flight, which originated at Toronto Pearson International Airport, had been cleared by air traffic control to land on San Francisco's runway 28R and was on final approach to land on that runway; however, instead of lining up with the runway, the aircraft had lined up with the parallel taxiway Charlie on which four fully loaded and fueled passenger airplanes were stopped awaiting takeoff clearance. The flight crew initiated a go-around prior to landing, after which it landed without further incident. The aircraft on the taxiway departed for their intended destinations without further incident. The subsequent investigation by the National Transportation Safety Board (NTSB) determined that the Air Canada airplane descended to 59 feet (18 m) above the ground before it began its climb, and that it missed colliding with one of the aircraft on the taxiway by 14 feet (4.3 m). The NTSB determined the probable cause was the Air Canada flight crew's confusion of the runway with the parallel taxiway, with contributing causes including the crew's failure to use the instrument landing system (ILS), as well as pilot fatigue. A retired pilot stated the runway confusion that almost happened "probably came close to the greatest aviation disaster in history" as five airplanes and potentially over 1,000 passengers were at imminent risk.
