Lesson 9 Introduction


Birds are born having all the parts they need to fly. When the time is right, they know how to use all those parts to fly when they jump out of the nest.
For humans, inventing a machine that flies has been difficult. Many years of observations, tests, and failures were required to reach the point where we are today.
Flying is complex. Pilots must understand all the parts of the airplane and how to control them. They must know how the forces of flight are acting on an airplane and how best to use them to direct the airplane.
Let's see if you can apply what you have learned this far to build an airplane. Click on the link and give it a try!
