Matching Pairs Types of planes (1)Online version Have fun playing! by Anna Rapti 1 2 3 4 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. 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. 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. 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.
