Traveling at that height, the temperature could be 30 degrees below zero Fahrenheit—maybe colder.
They could, maybe, get up a few thousand feet before the cold and oxygen issues factored in, but definitely not to 30, feet. No, what these people would need is a plan.
A pressurized suit with thermal protection and an oxygen system could keep them safe for the flight, Kring suggests. Theoretically, with enough oxygen in the system, people on the wing could make it from China to Mexico, Russia to South Africa, or anywhere to anywhere else.
Other than that? Thrown clear of the aircraft and rendered unconcious, he fell four miles before crashing through the glass roof of St. Nazaire train station, shattering it and miraculously surviving, though with severe injuries. She was the sole survivior of a bomb placed onboard JAT Flight in which saw her plummet more than 30, feet. Experts believe she survived by being trapped by a food cart inside a section of the aircraft's fuselage which subsequently landed at an angle on a heavily wooded and snowy mountainside in Czechoslovakia.
Soviet Air Force lieutenant Ivan Chisov and Royal Air Force sergeant Nicholas Alkemade also survived in similar circumstances, thrown clear of bombers in the Second World War before landing in a mixture of snow and trees.
Remarkably, Alkemade only suffered a sprained leg after falling 18, feet. The following infographic provides a list of known occasions where people survived extremely high falls without a parachute.

At 10, feet above sea level, the normal saturation for a human breathing regular air is 87 percent. Go to 18, feet without supplemental oxygen and the saturation drops to 80 percent thanks to the partial pressure of oxygen being just 21 percent of the atmospheric pressure at any altitude.
That means we're going to start getting woozy and hypoxic, and unless we've added substantial hemoglobin to our bloodstreams by living at very high altitudes, we'll eventually black out.
There is an altitude range, however, where even breathing percent oxygen with percent partial oxygen pressure from a little yellow mask in a jetliner won't provide enough life-sustaining oxygen saturation in the bloodstream. That point is around 28, to 30, feet.
Above that, there isn't enough oxygen pressure even when breathing pure oxygen to shove the O2 molecules across the membranes and into the hemoglobin.
The cure is pressure breathing, which you can't do with yellow supplemental masks. Pressure breathing oxygen masks the type you'll find in the cockpit force pure oxygen into your lungs at a higher pressure than the surrounding air and keep your blood oxygen saturation level above 87 percent.
But the techniques for pressure breathing require practice in an altitude chamber, and are so foreign to our normal methods of respiration that few passengers would be able to cope with it in an emergency even if we provided such masks in the back. Your pilots, however, are well-trained, and have pressure-breathing oxygen masks beside them at all times. You have nine to 15 seconds to place the mask over your own face before you lost consciousness.
