“I saw a National Geographic documentary some years ago about two British accomplished mountain climbers, George Mallory and Andrew Irvine who tried to summit Everest without oxygen and perished. It was 1924.”
The thing is, they DID have oxygen, but the devices were rather primitive compared to what we have today.
Yeah, I guess they were primitive. Maybe I’m wrong, but I thought they were going to try it without Oxygen.
I’ll have to go back and re-watch it….
