All Nippon Airways Flight 60 was a Boeing 727-81 aircraft making a domestic commercial flight in Japan from Sapporo Chitose Airport to Tokyo Haneda International Airport. On February 4, 1966, all 133 people on board died when the plane mysteriously crashed into Tokyo Bay about 10.4 km from Haneda in clear weather conditions while on a night approach. The accident was the worst involving a single aircraft in Japan and also the deadliest accident in the country until All Nippon Airways Flight 58 crashed five years later, killing 162 people.
