The wreck of the AS350 helicopter remains wedged in a crevasse towards the top of the glacier.

Four British and two Australian tourists, and the New Zealand pilot, died when the AS350 helicopter crashed on the glacier.

Leo Murray, the investigator-in-charge, said the Aerospatiale AS350 Squirrel helicopter impacted into farmland to the west of Ballynacally in rising terrain.

Crash helicopter 'has good safety record' Pilots say the AS350, a make of helicopter also called the Squirrel, has an excellent safety record.

The AS350 B3 helicopter that Fakhar-e-Abbass was flying is not designed to fly above 4,600 meters; the rescue took place at almost 5,900 meters.

An AS550 Fennec helicopter was, fundamentally, similar to an AS350 Ecureuil, which Storm had once flown through a typhoon in the Gulf of Tonkin.
