It has been over 100 years since the Wright Brothers first flew a plane. How quickly things change. These days, experts are working on planes that do not even need pilots. The planes are called unmanned aerial vehicles (UAVs). They are becoming very popular. These planes can do everything from firing weapons to watching for bad weather. How do they work?
