How are airplanes artificially pressurized?
In order to make sure all airplane passengers are comfortable, and also that the trip is survivable, most airplane cabins are artificially pressurized. This pressure is caused by a number of different processes, but the main way airplane cabins are artificially pressurized is by pumping compressed air into the cabin. Without this air pressure, passengers would likely lose consciousness or become very lethargic. Most airplanes are artificially pressurized once the aircraft reaches an altitude of more than 10,000 feet (3,048m). With a cruising altitude closer to 30,000 feet (9,144m), passengers would likely lose consciousness in a matter of seconds without the cabin being artificially pressurized. This would likely lead to death, simply from the lack of oxygen alone. In order for an airplane cabin to be artificially pressurized it first must be airtight. If there are places where air can get out, the plane loses pressurization very quickly. This is why in movies, for example, once an air
