The Boxkite is an early type of aircraft designed by Lawrence Hargrave in the late 19th century. It features a box-like structure made of lightweight materials, which allows it to generate lift when pulled by a tether. The design was significant in the development of kites and contributed to the understanding of aerodynamics. Boxkites were among the first to demonstrate controlled flight principles and were used for various experiments in aviation. Their unique shape and design influenced later aircraft designs, paving the way for advancements in the field of aviation and the eventual creation of powered flight.
