Delta Flight 191 Memorial

Delta Flight 191 Memorial. In Memoriam. , On August 2, 1985, Delta Air Lines Flight 191, a Lockheed L-1011, crashed on final approach to the Dallas Fort Worth International Airport, approximately 2 miles due east of this site. A total of 135 persons died in the accident, including 126 of the 152 passengers on board, 8 of 11 crew members, and one motorist on the ground. , The National Transportation Safety Board investigation deemed the meteorological phenomenon known as wind shear pushed the aircraft to the ground well short of the runway. Investigators also cited the aircraft's lack of ability to detect wind shear as a contributing cause. , In 1988, the Federal Aviation Administration ordered all commercial aircraft to have on-board wind shear detection systems installed by 1993. Many airports across the United States, including DFW, also installed ground-based wind shear detection equipment. , Due to the improved ability to detect wind shear, the number of aircraft accidents caused by wind shear has dropped significantly since 1995.
