Everest: Beyond the Limit is a Discovery Channel reality television series about yearly attempts to summit Mount Everest organized and led by New Zealander Russell Brice. For the first season, a 17 member production crew followed 11 climbers, three guides, and a team of Sherpas up the mountain in April and May 2006. The first season's six-part series included double-amputee Mark Inglis' ascent and brief footage of British climber David Sharp, who died in the attempt. The series was shot using high altitude equipment and helmet mounted cameras worn by Sherpas.

Series looking at three Everest expeditions - by balloon, canoe and climbing without oxygen.

In WWII Pat Jamieson is a scientist working, with Government support, on a high-altitude oxygen mask for fighter pilots. But he has nowhere to conduct his research in secret until he meets Jamie Rowan, a woman with an unused house with a scientist's basement. Jamie has no hopes of marrying for love (and neither does Pat) but Jamie wants to help the war effort and she likes this quirky scientist and his dog, so to satisfy the proprieties they agree on a business arrangement: a marriage of convenience and partnership. They happily work on oxygen mixes instead of honeymooning.
