Interesting thing oxygen, it causes rust, liquid oxygen can be breathed; George Mallory and Irvine might have reached the summit of Everest, the evidence indicated a fall from much higher up and Mallory's body was near the summit ridge, in good weather they would definitely have succeeded, amazing feat considering they had no modern lightweight gear, climbed from the base of the mountains unlike driven in or flown in modern climbers. The ease of getting to locations cracked many records, once the journey itself often proved impossible, the weather window opened into tourist season attempts on Everest in a later era.
