Were there other issues involved in the fatalities around 12-14k ft? Freezing etc? In aviation rules you can have passengers at 12k ft without oxygen for an unlimited amount of time. The crew needs to use oxygen if you're between 10k and 13k for more than 30 minutes. Above 13k both crew and passengers must use oxygen immediately (EASA rules, FAA is different). So they seem to consider 12k to not be dangerous to passe…

I went from sea level to 11k feet in the same day many times before. I would say the altitude effect is there but not as much as you might expect. A little quicker to be out of breath a little longer to recover it. Not sure what it is like at higher elevations or greater daily altitude delta.
I guess fitness makes a difference from what these other comments are saying. My ex-wife and I lived in Long Beach (which is obviously sea level) when we were in ROTC and pretty regularly took day trips out to San Gogornio and walked to the summit in about five hours, which is ~11,500ft. Not once did that have any noticeable effect, but we were both pretty serious runners back in the day trying to become Army officer…
The better your heart is at getting oxygen into your muscles and organs, the better it can compensate for less oxygen.
Not a bulletproof solution to altitude sickness, but it's definitely one of a lot of variables that matters. It's also just true that some people are way more susceptible regardless, I've got friends who run competitive marathon times who get splitting headaches flying from sea level to denver.

"You" don't take antacid after eating unless "you" have problems with your stomach acid or something. Neutralizing your stomach acid isn't generally a smart thing to do, because it's acidic for a reason (digesting food). Some people even recommend not drinking to much water with your meals because it dilutes your stomach acid, though that might be overly cautious. Whether adding baking soda to food makes you feel ful…

> 12-15K feet just isn’t that high in the scheme of things. Many peaks in the western US are in that range or more. The highest peak in the contiguous United States is Mt. Whitney at ~14.5k feet

It's a tiring climb and a tiring descent, but I never felt a hint of altitude-related discomfort.
I lived near sea level and didn't often go anywhere more than about 1,000 feet above sea level in daily activities.

Very much dependent on age, rest and general conditioning. I went from sea level to 14K at Pikes peak in 1 day and it was quite uncomfortable. I managed, but folks who lived in Denver with lower physical fitness levels than me, did better.
Agreed, we live at ~5K and went up to Pikes Peak; my wife and I had no problems (beyond minor headache), but my son's lips were turning blue and he was feeling pretty bad. Other amusing things from that trip: we went up there the 3rd of July, and it snowed. We charged the car in Colorado Springs before we left, got up to the peak with 36% battery remaining. My wife worried we wouldn't be able to make it back. Got bac…

But the temperature does make it worse. Your body is trying to generate heat, which increases oxygen demand. Your blood vessels are constricting, so circulation is less efficient, limiting oxygen distribution. All together, this creates all sorts of health risks.
Sitting in a comfy plane seat browsing the internet is not the same thing. Besides, even healthy adults just sitting can experience mild hypoxia effects above about 10k ft - fatigue, mild cognitive effects, headaches. But if you're just sitting, it's generally tolerable. Of course, you don't want pilots working in those conditions for any length of time.

#130To be honest I'm surprised insurance is offered at all. I did the EBC trek a couple years ago. The temptation to take a helicopter down was real & I didn't have insurance.
Rescue insurance was required by the trekking company when I did EBC a few years back.
