The Jumbo Jet

The Boeing 747 is one of the beggest airplant
in the world. It's the elephant of airplanes.
That why they sometimes call it a "Jumbo-jet".
It can fly for many hours and take people from one big city
to another. A jumbo jet has 18 wheels.
Each wheel is more then a meter high sixteen sheels
are in the back and two wheels are in the front.
When the airplant is about to land, they come out again.
The Boeing 747 has four big engines. two on each wing.
the engines go round very quickly.
This sucks in air and creates the push
taht makes the airplants fly in the sky.
With the movement of the wings it can up,
or down, and trun left or right. the smaller wings
on the back are especially important for steering
the airplane in the right direction.
The front of the airplane looks like a giant egg.
Inside is where the pilot sit and fly the airplane.
