About 1712 e.d.t. on June 23, 1976, Allegheny Airlines, Inc., Flight 121, a Douglas DC-9-31, crashed on the Philadelphia International Airport, Philadelphia, Pennsylvania; the wreckage came to rest about 6,000 feet beyond the threshold and about 350 feet to the right of the centerline of runway 27R. Of the 106 persons on board, 86 persons were injured; there were no fatalities. The captain of Flight 121 had conducted an instrument approach to runway 27R in visual conditions as a thunderstorm passed over the airport in a north-northeasterly direction. When near the threshold the captain initiated a go-around from a low altitude and entered rain of increasing intensity. Shortly thereafter, the aircraft was seen descending in a noseup attitude with the landing gear retracted. After striking tail first on a taxiway about 4,000 ft beyond the threshold of runway 27, the aircraft slid about 2,000 ft and stopped. The National Transportation Safety Board determines that the probable cause of this accident was the aircraft's encounter with severe horizontal and vertical wind shears near the ground as a result of the captain's continued approach into a clearly marginal severe weather condition.
