Answer:
Airplanes are pressurized because the air is very thin at the altitude they fly. The average passenger jet has a cruising altitude of about 30,000 to 40,000 feet. At this altitude humans can't breathe very well and our body gets less oxygen.

Answer:
Airplanes are pressurized because it protects pilot, crew and passengers from hypoxia. They are designed to pump air into the cabin to copy the 14.7 pounds per square (PSI) of pressure that's found at sea level
