June 2011 Himalayan tragedy

We have been contacted by the mother of a young woman who died tragically in the Himalayas in June 2011.

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 there are no mountains at 9000m (29700ft) above sea level, commercial aircraft do fly this high. The pressure on the outside of the cabin of a plane at this altitude would be the same as seven and a third metres of sea water. Thankfully, the aircraft is pressurised to an altitude of around 2500m.
