Certainly one of the worst crashes in civilian history and probably the second worst Chinook crash of all time after the loss of 46 souls aboard the US Army Chinook which crashed on September 11th 1982 near Mannheim, Germany.
The BIH disaster heralded the end of the type's UK commercial debut but, across the North Sea, Norway's Helikopter Service kept them running a while longer despite a number of in-flight engine failures the year after the BIH tragedy!
Despite several high profile indicents (some of them crew induced) the type remains an indispensable military asset.
