How aviation disasters led to concrete safety changes
Every major aviation accident led to concrete changes that made flying safer.
The industry learns from failure. When something goes wrong, investigators find the root cause and regulators mandate changes to prevent it from happening again.
This is why modern aviation is so safe - each disaster taught us lessons written in regulation and procedure.
Key Accidents: Tenerife (1977), United 173 (1978)
The Tenerife disaster killed 583 people partly due to miscommunication between pilots and ATC. United 173 crashed after the crew fixated on a landing gear issue and ignored fuel warnings.
Changes Made:
Key Accidents: JAL 123 (1985), Aloha 243 (1988)
JAL 123 crashed killing 520 after a botched repair weakened the rear bulkhead. Aloha 243 lost part of its roof mid-flight due to metal fatigue.
Changes Made:
Modern aircraft have numerous automated safety systems that didn't exist in earlier decades:
Each of these systems exists because accidents proved they were needed.
