History
It's impossible to know when the first paper airplane was created, but it was likely long before the first real airplane took flight. Paper folding and kite-making, both popular art forms in Asia, may have resulted in some of the first paper airplanes hundreds of years ago.
Function
Paper airplanes are a lot of fun, but they hold scientific value as well. They can help teach the basic concepts of engineering and aerodynamics.
Features
Paper airplanes are typically made with a standard 8 1/2 X 11" sheet of paper. They must have wings, but may have a tail, rudder, tail fins or keel, depending on the design.
Considerations
It is important to fold paper airplanes carefully, so they are well balanced. Even a small variation might change the flight pattern.
Fun Fact
The World Record for paper airplane flight belongs to Ken Blackburn. His plane stayed aloft for 27.6 seconds in 1998.
