How The Rocket Gets Its Air

Before any one gets to go on the rocket we put air in side of it the air comes from a rocket pump it looks just like a bike pump but the rocket pump is much biger the rocket pump is a robot we are going to call it the rock pump for only rockets that don't use gas because the other rockets use fire and this rocket that i am talking about right now it uses air at the rock pump is in side of the rocket.
