Adrian Ballinger and Cory Richards were sponsored by Eddie Bauer to climb Everest, and they relayed information from the Everest climb using the smartphone software application and service Snapchat. Mount Everest has had a 3G wireless data communication network since 2010. One of the things that was reported by them, was that bottled oxygen was stolen from them and there was some bad behaviour up there. The bottled oxygen was there for emergency back-up if they ran into trouble. Cory Richards summited Mount Everest without oxygen and returned safely, and Adrian made it almost to the top also. Another famous mountaineer, British climber Kenton Cool achieved his 12th Everest summit (the second-highest number of Everest summitings for a foreigner after Dave Hahn), and US celebrity mountaineer Melissa Arnot, completed her sixth summit, and achieved her personal goal of climbing Everest without supplementary bottled oxygen. This also turned out to be the most summits for a foreign female (not Nepali or Chinese), and one of the first US women to summit and survive without supplementary oxygen.
