Pilots and passengers generally need supplemental oxygen when flying above 12,500 feet to 14,000 feet to maintain adequate oxygen levels.

How do planes fly if they are so heavy?

Planes generate lift through their wings using the principles of aerodynamics. The shape of the wing and the speed of air over and under it create pressure differences that lift the plane off the ground.
