Mike,
Great fishing but a little compassion on your part - people are so passionate about this because 2 Puma aircrew were killed in Kosovo in 2003 - the BOI found it was partially attributable to a lack of training in whiteout conditions in high mountains.
IIRC this training had been previously carried out but was discontinued due to lack of funds.
So when your mates are splattered across a snowy forest in Kosovo because some bean counter tried to save money it makes you somewhat prickly.
Given your profile I am sure you are au fait with the crash. So please cast your net elsewhere.
