The Bell Aircraft Corporation was an American aerospace manufacturer founded in 1935 by Lawrence Bell. The company is best known for producing military aircraft during World War II, including the iconic Bell P-59 Airacomet, the first American jet fighter. Over the years, Bell expanded its focus to include helicopters, becoming a leader in rotorcraft technology. In the post-war era, Bell Aircraft developed several notable aircraft, such as the Bell X-1, which was the first plane to break the sound barrier, piloted by Chuck Yeager. The company also played a significant role in the development of the Bell UH-1 Iroquois, commonly known as the "Huey," which became famous during the Vietnam War.
