It isn't a matter of why they need it! Some planes are just designed with jet engines! Jet engines take a small amount of air and push it out fast whereas props take a large amount of air and push it back slower! Some planes just have jet engines!

Do airplanes fly over hurricanes?

What do planes and jets fly in?
They fly in air. High-performance military fighter jets have engines powerful enough that they can fly straight up, like a 'rocket ship'. But aside from those, all airplanes need air in order to remain aloft.
Do blimps need engines to fly?
no, but you need engines to control the airship (AKA blimp)
Why do airplanes fly in the troposphere layer?
Because that is where the air is denser and aircraft fly better.
Are airplanes jets?
Yes, jets are airplanes but they are called supersonic airplanes.
Do Nascar drivers fly airplanes and jets?
