The Delta Air Lines, scheduled, international, passenger flight, was being conducted under the provisions of Title 14 CFR Part 121, with an Instrument Flight Rules (IFR) flight plan filed. Visual meteorological conditions prevailed. One flight attendant was seriously injured, and the airline transport pilot, first officer, flight engineer, nine flight attendants, and 211 passengers sustained no injuries. The flight departed Atlanta at 2127 eastern daylight time (0127 GMT). The flight was near Benbecula, a navaid on an island off the coast of Scotland, when the accident occurred. There was no report of turbulence. The sky was clear and the air was smooth. There were no mechanical problems reported with the aircraft. The A-Line flight attendant advised the Captain that one of the flight attendants had stepped on a salt shaker, in the First Class Galley, breaking her left ankle and cutting one of her fingers.
