the 176 passengers and crew. The subsequent National Transportation Safety Board (NTSB) report on the incident blamed the flight crew for failing to monitor the aircraft's instruments properly. Details of the incident are now frequently used as a case study in training exercises by aircrews and air traffic controllers. During 2004 in the United States, pilot error was listed as the primary cause of 78.6% of fatal general aviation accidents, and as the primary cause of 75.5% of general aviation accidents overall. For scheduled air transport, pilot error typically accounts for just over half of worldwide accidents with a known cause. 28 July 1945 – A United States Army Air Forces B-25 bomber bound for Newark Airport crashed into the 79th floor of the Empire State Building after the pilot became lost in a heavy fog bank over Manhattan. All three crewmen were killed as well as eleven office workers in the building. 24 December 1958 – BOAC Bristol Britannia 312, registration G-AOVD, crashed as a result of a controlled flight into terrain (CFIT), near Winkton, England, while on a test flight. The crash was caused by a combination of bad weather and a failure on the part of both pilots to read the altimeter correctly. The first officer and two other people survived the crash. 3 January 1961 – Aero Flight 311 crashed near Kvevlax, Finland. All twenty-five occupants were killed in the accident, which was the deadliest in Finnish history. An investigation later determined that both pilots were intoxicated during the flight, and may have been interrupted by a passenger at the time of the crash. 28 February 1966 – American astronauts Elliot See and Charles Bassett were killed when their T-38 Talon crashed into a building at Lambert–St. Louis International Airport during bad weather. A NASA investigation concluded that See had been flying too low on his landing approach. 5 May 1972 - Alitalia Flight 112 crashed into Mount Longa after the flight crew did not adhere to approach procedures established by ATC. All 115 occupants perished. This is the worst single-aircraft disaster in Italian history. 29 December 1972 – Eastern Air Lines Flight 401 crashed into the Florida Everglades after the flight crew failed to notice the deactivation of the plane's autopilot, having been distracted by their own attempts to solve a problem with the landing gear. Out of 176 occupants, 75 survived the crash. 27
