United Airlines was founded by aviation pioneer William Boeing who is known most notably for his Boeing Airplane Company that has designed our commercial aircrafts for a generation. Originally used as a carrier service, in 1933 it quickly expanded into a transportation system that brought Americans around the country on a Boeing 247 without having to switch planes to a connecting flight in one of the landing states. Once World War II was taken to allied front, United Airlines was used as an airbase with their aircrafts redesigned as bombers to help with the war effort. Post-war United Airlines progressed heavily with technology with their cabins and large commercial planes which continued to grow along with the 21st century and is now known as one of the largest and most reliable Airlines in the world.
