By Gopal Sharma KATHMANDU (Reuters) -Four British climbers became the first to scale Mount Everest on Wednesday using Xenon gas, which helped them save several weeks that mountaineers need to get used to high altitudes,

Known for its stability and lack of reactivity, xenon is found in trace amounts in Earth's atmosphere. Despite being rare, it has several important applications.

A British climber who scaled Mount Everest for the 19th time, breaking his own record for the most ascents of the world’s highest peak by a non-Sherpa guide, says he is already planning his next attempt.
