An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners.
The Similarities Between The Two. There is ALOT of info about airplanes, yes. Some important and some not really, I'm going to tell you the most important things about an airplane. Airplanes are fixed-wing aircraft that are propelled through the air by engines. They are used for transportation, research and military purposes. The 4 forces of flight are: lift, drag, thrust & weight. Aircraft wings feature a shape called an airfoil which creates lift as the plane moves through the air.
