What Are Planes?
On March 31 1903, Richard pearse was the first person to fly a aircraft successfully. On December 17, 1903, Wilbur and Orville (Wright Brothers) made four short flights at Kitty Hawk in North Carolina with their first powered plane.
Some planes are used for transportation and there are also military planes. There are many different kinds of plane and some of them are
pre 1914 plane, Gliders, rotorcraft, NA 40 Bongo and etc.
There are four forces of flight in a plane and they are the Lift, Drag, Thrust and weight.
Drag is the smooth force that dislike an aircraft's motion through the air. Drag is generated by every part of the airplane even the engines.
All planes need wings but helicopter don’t need wings because they have the propellers.
A plane needs small wing to get thrust but if a plane needs more lift it will need bigger wings.
As you can see that are not just used for transportation they are also used for military.
