A commercial airliner that went down at sea in 2007 in East Asia and no debris were found for a week.
In fact the fuel was still burning on the surface of the water as the first pieces of wreckage were recovered.
Interesting, though, how we refer to TWA800 ( which is correct, it was the actual call sign of the aircraft that day) vs MH370 ( which is incorrect, that's the itinerary flight number that means something only to passengers and route planenrs ). The actual call sign was MAS370.
