Wasn't it a Saudia L-1011 about 30 years ago where the plane had a major fire, landed safely, but the flight crew either didn't de-pressurize the cabin or release the emergency doors so they couldn't be opened and everyone inside (over 250) died of smoke inhalation? As I recall it sat on the end of the runway for over 15 minutes before a door popped open. But I remember a KLM flight attendent giving special instructions to us exit row passengers one time telling us not to pull the door release handle just to test things out or she would have a day's paperwork to fill out.
