In 1983, a fire broke out in a lavatory on Air Canada Flight 797. The plane landed but 23 people on-board died. After that, smoke detectors and automatic fire extinguishers were mandated in aircraft lavatories.
In 1996, hazardous cargo on ValuJet Flight 592 caught fire. The plane crashed in the Florida everglades and 110 people died. It led to new cargo hold safety rules.
