A transportation that flies. Airplanes!
2
What is an airplane? An airplane is a fixed wing vehicle that flies through the air. Airplanes can have jet engines or a propeller driver.
3
How do airplanes fly? An airplane must be in constant motion- its wings slicing through rushing air to create lift-in order to stay up; moving air is also required to steer it. In other words, a plane cannot fly without the power of its engines thrusting it through the air.
4
… Also … Small airplanes generally use piston engines, which turn propellers that push the aircraft through the air in the same way that a boat propellers push vessels through the water.
5
How do wings help airplanes fly? Airplanes are able to lift into the air and stay there because of the shape of their wings.
6
… And … An airplane wing is flat on the bottom and curved on the top.
7
… also … A plane’s engines push it forward and air divides to travel around its wings.
8
… finally … The air that passes over the larger curved top moves faster than the air that passes under the flat bottom.
