Main Idea: The Wright Brothers

The Wright brothers are famous because they were inventors.
Beginning at a young age, they built kites, bicycles, and other
machines. That is not why they are famous, though. Orville and
Wilbur Wright were not the first to experiment with building a plane.
They are known for designing and building the first successful airplane.
Their first fight in 1903 only lasted 12 seconds. It is still considered
successful. Now, fying in an airplane is a normal way to travel. We can
thank the Wright Brothers for being creative and brave. They worked
hard to create the firrst successful flying machine.
