The Bristol Boxkite, also known as the Bristol Biplane, was a British aircraft designed by the Bristol Aeroplane Company in 1910. It was one of the first successful biplane aircraft designs and played an important role in the development of aviation during the early years of the 20th century.

The Bristol Boxkite was a simple design, with a wooden frame covered in fabric and powered by a 50 horsepower Gnome rotary engine. It had a wingspan of 12.8 meters and a length of 9 meters. The aircraft was capable of a top speed of around 70 kilometers per hour and could fly for up to 2 hours.

The Boxkite was widely used for both military and civilian purposes in the years leading up to World War I. It was used for reconnaissance and training by the British Army and was also used by several airlines for passenger transport, including the British airline Airco, which was founded by the Bristol Aeroplane Company.

The Bristol Boxkite was also an important aircraft for experimental purposes. It was used to test new technologies, such as radio and wireless telegraphy, and was also used to test the feasibility of air-to-ground communications.

In total, more than 100 Bristol Boxkite aircraft were produced between 1910 and 1914, making it one of the most successful aircraft designs of its time. The aircraft’s success helped establish the Bristol Aeroplane Company as one of the leading aircraft manufacturers in the world and contributed to the rapid development of aviation technology during this period.
