Jet Airplane Technology

Inventors continued to improve airplanes after the Wright Brothers, and this led to the invention of jets, which are used by both the military and commercial airlines. A jet is an airplane propelled by jet engines. Jets fly much faster than propeller-powered aircraft and at higher altitudes - as high as 10,000 to 15,000 meters (about 33,000 to 49,000 ft).
Two engineers, Frank Whittle of the United Kingdom and Hans von Ohain of Germany, developed the jet engine during the late 1930s.
