Boeing B777 Descent Below MSA and Near CFIT

On 24 July 2011, a Boeing 777-300 on a scheduled passenger flight from Bangkok (Thailand) to Melbourne (Australia) descended so far below the vertical profile for the night non precision approach procedure being flown in VMC at destination that ATC, observing that the aircraft was below the minimum safe altitude for the range from touchdown, instructed the aircraft to fly a go around. However, despite acknowledgement, this instruction only resulted in the descent being arrested and the go around did not commence until a further instruction to do so was given nearly a minute later.
