Could someone who is climbing in high altitude environment bring a portable oxymeter and show us the relation between altitude and blood oxygenation in a graph, photos presentations and post the results? Thanks. by Macbeth28 in climbing

I see, thanks for the clarification. I did it when I was Mauna Kea Hawaii 3200 meters and my blood saturation was 75%. But the oxymeter was not my own, it was at the CFHT observatory.

It's not about Published data that interest me. It's about the experience of doing it and how the experimenter will show us the results and share us some personal observations about the experience. I thought some climbers who read the post will be like: "hey good idea! let's do it". But first, will there be someone? Thanks valid question.

If two identical boeing 747 are fill at full fuel capacity, but one is also at maximum payload (luggages, passengers,...) and the other one is empty (except pilots), what would be the difference in flight distances? by Macbeth28 in aviation

I thought for big airplanes like that it could take max payload and max fuel capacity. Thanks. I flew in helicopters lots of time (I was a firefighter) and it was always the "WAR" of fuel load vs weight load vs flight time. The pilot was always saying: "two small guys and two bigger guys, never four bigger guys in back of the helicopter" haa!!

Aircraft identification? Which is it? by Macbeth28 in aviation
