Rockets fly at speeds 5 to 10 times the speed of sound (3500 - 7000 MPH) as they orbit. They have a very powerful engine in order to travel at this speed.
These planes carry passengers and cargo. Their speed is just below the speed of sound (350-750 MPH). Their engine is very powerful and they can travel very quickly with many people and goods.
760 MPH is the speed of sound. These planes can fly up to five times the speed of sound (760 -3500 MPH). They have a special engine and they are designed with lightweight materials.
Most of the early planes can fly at 100-350 MPH. Examples of this kind of planes are the two- and four-seater passenger planes and seaplanes that can land on water.
