Why would slaves be interested in how much their masters keep? :)
Airplanes are able to fly due to revving up their engines and going down the runway really fast. Once they get to a certain speed, due to the curvature of their wings, the wind flows faster under the bottom of the wing and lifts the entire aircraft up into the sky.
Once airborne, the pilot starts fooling around with the levers, buttons, and switches in the cockpit, to make the airplane do different things while in the sky.
