The Handley Page Aircraft Company was a British aircraft manufacturer founded in 1909 by Frederick Handley Page. The company played a significant role in the development of military and commercial aircraft during the early 20th century, particularly during World War I and World War II. One of its notable contributions was the design of the Handley Page Victor, a strategic bomber that served in the Royal Air Force. The company also pioneered various aviation technologies, including the Handley Page slot, which improved aircraft performance by enhancing lift at lower speeds.
