Following the crash and the ensuing NTSB report , DFW 's DPS made improvements to its post-crash notification system , including the introduction of an automated voice notification system to reduce notification times . In 1988 , following the crash of Delta Air Lines Flight 1141 while taking off from DFW , DPS completed its notification of nearby emergency services in 21 minutes ; the NTSB described this as a " significant improvement " over response times after the Delta Flight 191 crash . Based on the improved response times , the NTSB issued a Safety Recommendation on January 9 , 1990 , calling for airport executives nationwide to consider the benefits of using automated voice notification systems for their emergency aid notifications . Pilots were also required to train to react to microbursts and to quickly take evasive action in order to safely land the plane
