Is this a bit like someone saying you shouldn't use fleet carriers? It's not proper exploring!

Four British former special forces soldiers have set a record by climbing Mount Everest in under five days without acclimatising on the mountain, as part of a high-speed expedition controversially aided by xenon gas.
Xenon was used to help them pre-acclimatise to low oxygen at high altitudes. Climbers usually spend between six to eight weeks on Everest before summiting.
Adrian Ballinger, who heads another expedition team climbing Everest from the Chinese side to the north, also makes his clients undergo pre-acclimatisation training like using hypoxic tents to shorten time on the mountains. But he opposes using xenon gas.
"If you're promoting xenon as a performance enhancer, but you're not also willing to examine what that means for fairness and integrity in the mountains, it's a problem," he told the BBC.
"People are grasping at shortcuts instead of doing the real work of acclimatisation and training."

Everest: British soldiers make history with new method
The former special forces troops used xenon gas to acclimatise to climbing at high altitudes more quickly.
