In that incident, all 18 people on board were saved. Eight people have already been confirmed dead from accident with another eight feared dead.

The Super Puma is widely used because it is considered to have a good safety record.

A preliminary Air Accident Investigation Branch (AAIB) report into the North Sea crash concluded Michael Tweedie, commander of the helicopter, had been unable to identify the landing pad of the BP platform the helicopter was attempting to land on.

Since then, the AAIB said that Bond has issued fresh guidance to pilots who were trying to land in adverse weather conditions. It is believed there were no adverse weather conditions involved in this crash.

Those who work in the oil industry say every helicopter incident has to be treated individually. Traveling to and from oil platforms by helicopter can be a hazardous journey. 

The worst incident occurred in 1986, when 45 people died in a Chinook helicopter crash.

In 1992, eleven were killed when a Super Puma crashed shortly after take-off.
