Expansion And Contraction

a: Cabin of a passenger jet ~
b: a big balloon

What: "The cabin of a passenger jet is like a big balloon that is blown up and deflated every time a plane takes off and lands, sealing the passengers inside an environment that is safe and comfortable, while the plane cruises at thirty thousand feet, an altitude that human beings can't tolerate for long."
