The man who ran out of air I'm not sure where best to post this (feel free to move mods). A great read from the BBC news website. More a feature article than a news article. It may have some relevance to avalanche survival although it doesn't specifically mention this (and I'm sure there are many other factors at play in a burial scenario). Thought it would interest a few in here. Also has a link to more stories in the series. Great reading.
