Just to keep the record straight, the Ansett ANA Viscount disaster was not a cabin fire, but an engine fire originating in an incorrectly lubricated Rootes blower. The resultant fire was uncontrollable, leading to (wing) structural failure in flight.
Not a correction to any of the historic facts, but I suspected that some readers may have thought of it as a cabin fire.
