Delta Air Lines Flight 191 was a regularly scheduled Delta Air Lines domestic service from Fort Lauderdale, Florida, to Los Angeles with an intermediate stop at Dallas/Fort Worth International Airport (DFW). On August 2, 1985, the Lockheed L-1011 TriStar operating Flight 191 encountered a microburst while on approach to land at DFW. The aircraft impacted ground over one mile (1.6 km) short of the runway, struck a car near the airport, collided with two water tanks, and disintegrated. The crash killed 137 people and injured 26 others. The National Transportation Safety Board (NTSB) determined that the crash resulted from the flight crew's decision to fly through a thunderstorm, the lack of procedures or training to avoid or escape microbursts, and the lack of hazard information on wind shear.
