Aviation Herald:
Incident: Jetstar A320 near Brisbane on Sep 22nd 2016, haze in cabin, engine shut down in flight
Doesn't evac[uation] generally imply using slides urgently, not walking off normally? The SMH story says "No emergency was declared" and quotes an airline spokesman: "The hazy smoke seen in the video happened when the aircraft had landed safely in Brisbane and shortly before the passengers disembarked," he said.
