.
1) Passenger and cargo planes
These planes carry passengers and cargo. Their speed is just below the speed of sound (350-750 MPH). Their engines are very powerful and they can travel very quickly with many people and goods.
1,235 km/h or 760 MPH is the speed of sound. These planes can fly up to three times the speed of sound . They have a special engine and they are designed with lightweight materials.

The SR-71B Blackbird holds the record for the fastest plane. It could travel at 3 times the speed of sound or 3,500 km/h or 2200MPH. It was a spy plane. |
3) Rockets
Rockets fly at speeds 5 to 25 times the speed of sound as they orbit around the earth. They have a very powerful engine in order to travel at this speed.

1. The Boeing travels very fast.
2. Rockets fly 4 times the speed of sound.
3. The seaplane can land on water.
4. The Concorde travels below the speed of sound.
5. The Concorde is faster than the SR-71B Blackbird.
