Question

How do planes stay up?

Answer 1

If you've ever watched a jet plane taking off or coming in to land, the first thing you'll have noticed is the noise of the engines. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditionalpropeller engines. You might think engines are the key to making a plane fly, but you'd be wrong. Things can fly quite happily without engines, as gliders (planes with no engines), paper planes, and indeed gliding birds readily show us.

Answer 2

Though airplane flight may appear miraculous, there is science behind it. Airplanes stay up in the air because of the aerodynamic force referred to as lift. Airplane lift, generated by each part of an aircraft, is a force that works in direct opposition to the weight of an aircraft.
