Key Facts at a Glance
On August 2, 1985, Delta Air Lines Flight 191, a Lockheed L-1011-385-1 TriStar, crashed while landing at Dallas/Fort Worth International Airport. The flight originated in Fort Lauderdale with an intermediate stop in Dallas, then aimed for Los Angeles. A microburst-induced windshear during the landing attempt led to a heavy, fast touchdown, a brief liftoff, and a second, fatal impact. This verified overview presents facts about the survivors, sequence of events, and outcomes, drawing on official reports and investigations.

What Happened: Sequence Verified by Investigation
Delta 191 approached Dallas/Fort Worth International Airport in thunderstorm conditions. As the airplane configured for landing, it encountered a microburst—a sudden, intense downward and outward burst of wind—that produced a severe windshear. The first officer attempted a go-around, but the aircraft had already descended too low. It touched down hard, briefly became airborne, then struck the ground again, breaking apart and catching fire. The National Transportation Safety Board (NTSB) concluded that the probable cause was the flight crew’s encounter with a microburst-induced windshear during landing, with contributing factors including lack of timely windshear information and limitations in detection and training at the time.
Who Were the Delta 191 Crash Survivors
Of the 163 people on board, 27 survived the crash. Survivors included passengers seated throughout the aircraft and one flight attendant. Many survivors sustained serious injuries—burns from the postimpact fire, fractures, and smoke inhalation—and required extensive medical treatment and rehabilitation. Some passengers who initially appeared uninjured later developed posttraumatic stress symptoms, highlighting the psychological toll alongside physical harm. Official medical reports note a range of outcomes, with some evacuating quickly and others enduring prolonged hospital stays. While the cockpit crew and cabin crew losses were significant among the deceased, the survivors’ accounts contributed to key findings about evacuation challenges and emergency response under chaotic conditions.
Investigation Findings and Determinations
The NTSB’s detailed investigation examined flight data, cockpit voice recordings, weather data, and survivor testimonies. Key conclusions included that the windshear was present and intense, and that cues available to the crew were insufficient for timely recognition and effective response. The report noted that the first officer’s decision to attempt a go-around after touchdown was appropriate given the emerging conditions, but the aircraft’s energy state and structural integrity had already been critically compromised. The investigation also addressed airport weather dissemination, crew training, and aircraft design factors, leading to safety recommendations that influenced future aviation regulations.
Safety Changes and Lasting Impact on Aviation
Delta 191 became a pivotal case in advancing windshear detection and response. In the aftermath, the aviation industry and regulators implemented critical improvements, including mandatory Doppler radar windshear detection systems on commercial aircraft, revised pilot training for windshear recognition and recovery, and updated airport weather reporting procedures. These changes, driven in part by lessons from Delta 191, are credited with reducing windshear-related accidents in subsequent years. The crash also spurred research into microburst forecasting and real-time alerting, contributing to a long-term decline in weather-related approach and landing incidents.
Passenger Accounts and Crew Response
Survivors and crew members described a sudden, violent touchdown followed by severe aircraft motion, fire, and dense smoke. Multiple evacuations were hampered by blocked exits and rapidly deteriorating conditions, leading to difficult choices for passengers and crew. Official narratives emphasize both acts of courage and the confusion that compounded an already dire situation. These accounts informed later evacuation modeling and guidance, highlighting the importance of clear crew instructions, accessible exits, and timely emergency response coordinated with airport services.
Legacy in Regulation, Training, and Industry Practice
The aftermath of Delta 191 reshaped multiple domains of aviation safety. Regulators strengthened requirements for windshear detection equipment and mandated recurrent training for adverse-weather operations. Airlines upgraded weather dissemination systems and cross-check procedures. Industry bodies created databases and simulation protocols to better prepare flight crews for extreme scenarios. Over time, these measures contributed to measurable safety gains, making operations more resilient to sudden atmospheric changes. The event remains a reference point in discussions about risk management, training efficacy, and technological resilience in commercial aviation.
