The airplane have air pressure nearly about the pressure that we are taking on the earth when we are standing on the ground but the pressure outside the airplane is very or lesser then why we don't get crushed inside the airplane?
The reason we are not crushed under the weight of air is, that the pressure inside our body is equal to the atmospheric pressure outside.
