On 22 Nov 1996 a US (ANG?) C130, call sign King 56, crashed in the Pacific Ocean after all 4 engines failed and the crew attempted to ditch the aircraft. 10 of the 11 crew were killed when the aircraft broke up on impact with the water.
I recall at the time there was much discussion about water landings/ditching and that whilst there had been several attempts there had never been a successful one.
