Lessons from Delta 191 How the Deadly Microburst Tragedy Transformed Aviation Safety - The Devastating Crash - Delta Flight 191's Encounter with a Microburst


The tragic crash of Delta Flight 191 in 1985 brought a devastating microburst event to the forefront of aviation safety.

The NTSB investigation determined that the wind shear associated with this microburst was the primary cause of the accident, leading to significant changes in how airlines and pilots recognize and avoid such hazardous weather conditions.

The implementation of enhanced weather detection systems and improved pilot training have since strengthened safety measures in the industry, transforming aviation to better protect passengers and crews from these rare but highly dangerous occurrences.

The microburst that Delta Flight 191 encountered was an extremely rare and powerful weather phenomenon, with estimated downdraft speeds exceeding 45 mph, more than twice the typical strength of a microburst.

The aircraft's weather radar system was unable to detect the microburst in time, as microbursts can develop and dissipate rapidly, often within just a few minutes, posing a significant challenge for pilots and air traffic controllers.

Investigators determined that the microburst's downward airflow effectively "slammed" the aircraft to the ground, with the plane's engines unable to generate enough thrust to counteract the powerful downdraft.

The crash of Delta Flight 191 was a pivotal moment that led the Federal Aviation Administration (FAA) to mandate the installation of wind shear detection systems at major airports, significantly enhancing the ability to identify and warn pilots of these dangerous conditions.

In the aftermath of the accident, pilots received enhanced training to recognize the signs of microburst activity and how to properly respond, including executing a "wind shear escape maneuver" to safely navigate through the hazardous weather.

The Delta Flight 191 tragedy spurred the development of new technologies, such as Doppler weather radar and onboard wind shear alerting systems, which have dramatically improved the aviation industry's ability to detect, predict, and avoid the devastating effects of microbursts.
