On November 4, 1970, a Pan American World Airways, Inc., Boeing 747-121, on a scheduled flight from John F. Kennedy International Airport, New York, to Orly Airport, Paris, France, encountered moderate to briefly severe turbulence at 27,000 feet as it passed Nantucket, Massachusetts. During the encounter which lasted approximately 4 minutes 10 seconds, 21 passengers and two stewardesses sustained injuries which ranged from minor to serious. The seatbelt sign was on at the time of the encounter and had been on since takeoff. Shortly after the turbulence encounter, the flight returned to John F. Kennedy International Airport, New York. The National Transportation Safety Board determines that the probable cause of this accident was the entry of the aircraft into an area of moderate to briefly severe turbulence associated with convective activity while numerous occupants were unsecured by seatbelts, even though the seatbelt sign was lighted.
