aeroTELEGRAPH has revisited the legacy of Swissair flight SR111, the McDonnell Douglas MD-11 that crashed into the Atlantic off Halifax on 2 September 1998, killing all 229 people on board. The piece focuses on how the disaster reshaped aviation safety, highlighting changes in fire-protection rules, cockpit procedures and crew training.
The accident unfolded after the crew detected an unusual smell, followed by smoke in the cockpit. Critical systems and instruments then failed, leaving the aircraft uncontrollable. The investigation later linked the fire to electrical wiring and unsuitable materials in the in-flight entertainment area.
The article places SR111 in a broader safety context, showing how hard lessons from the crash fed into revised checklists and stronger onboard fire-response training. It frames the disaster as one of the events that helped drive lasting changes across commercial aviation, with its impact still reflected in current procedures.
