American Airlines Flight 327 was a scheduled flight between T. F. Green Airport in Providence, Rhode Island and Tulsa Municipal Airport in Tulsa, Oklahoma, with intermediate stops in Boston, New York City, Syracuse, New York, Rochester, New York, Detroit, Chicago, St. Louis, Springfield, Missouri, and Joplin, Missouri. On January 6, 1957, the Convair CV-240-0 performing the flight crashed while performing an instrument approach to Tulsa Municipal Airport, killing one of the occupants and injuring seven. Weather conditions in the area were poor, and the aircraft descended through dense clouds and fog. As it approached the runway, it flew lower than the intended path and crashed into the ground 3.6 miles (5.8 km) north of the approach end of the runway. The probable cause of the crash was determined to be the captain's lack of alertness in allowing the first officer to continue an instrument descent to an altitude too low to permit terrain clearance.
