history of aviation
development of heavier-than-air flying machines. Important landmarks and events along the way to the invention of the airplane include an understanding of the dynamic reaction of lifting surfaces (or wings), building absolutely reliable engines that produced sufficient power to propel an airframe, and solving the problem of flight control in three dimensions. Once the Wright brothers demonstrated that the basic technical problems had been overcome at the start of the 20th century, military and civil aviation developed quickly.
