Photograph. Sir Hiram Stevens Maxim (1840-1916) designed and built this flying machine at Baldwins Park, Bexleyheath, Kent, in 1910. He had previously found fame by inventing the machine gun. The aeroplane had three pusher propellers and incorporated wing-warping and a wheeled undercarriage, but never actually flew.
