A British team of veteran ex-special forces soldiers summited Everest on Wednesday, expedition organisers said, in a bid to fly from London, climb the highest peak and return home within seven days.
The four men, who include government minister Alistair Carns, left London on Friday, pre-acclimatised to the low oxygen at high altitudes -- including the controversial assistance of xenon gas, a method that has raised eyebrows in the mountaineering community.
