Tragic death in Peru
Every year we are contacted in connection with tragedies in the mountains. Understandably, many people choose not to speak out about the loss of their loved ones. We are grateful to those who do, because the best way to prevent more people from dying is to publicise the risks.

Please take the time to read some of the accounts of deaths at high altitude on this website, and this brave report from a son, describing how he lost his father in Peru in May 2012.

 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.
