Not to detract from another great "What If?" article, but I think the biggest gotcha is right at the beginning: > Let's say your jet blows apart at 35,000 feet. You exit the aircraft, and you begin to descend independently. As far as I know, most airplanes don't do that nowadays. They tend to descend more or less in one piece (or several big pieces) to ground level and "blow apart" there. If they do blow apart at high altitude, it's probably due to an explosion which is apt to drastically reduce the chances of passengers being conscious (or alive) during the free-fall phase.
