June 2011 Himalayan tragedy

We have been contacted by the mother of a young woman who died tragically in the Himalayas in June.

Please read her deeply troubling account of the needless loss of a young life and help us to avoid this happening to anyone else.

Anyone travelling to high altitude should learn and follow the golden rules of altitude sickness.

 Although humans probably can't function above 9000m (29500ft), at least one person has survived a flight in the undercarriage of commercial aircraft flying over 30000ft for several hours. This may be because the extreme cold causes the body to shut down and so it uses less oxygen.
