History of Airplanes
Airplanes have been an important method of transportation and a vital part of warfare for over a century now. The Wright brothers invented the first successful airplane in 1903. However this was not the first thing to fly, before planes there were gliders, which were just planes without an engine. Ever since the Wright brothers invented the airplane it has developed a lot throughout history, from having two sets of wings to one, from being made out of wood and cloth to metal, and from using propellers to jets. Planes use four main factors to fly, lift, weight, trust, and drag.
