The development of the jet engine in the 1930s and 1940s was a major innovation in airplane design. The jet engine allowed for much higher speeds than the propeller-driven engines used in earlier aircraft and enabled airplanes to fly at much higher altitudes. Back then, airplanes were smaller and only suitable for a small group of people, but now there are more varieties of airplanes, However, the first recorded use of an airport was in 1909, at College Park Airport in Maryland, United States.
