A TWO-SEAT PTERODACTYL AIRCRAFT of fighter type powered by a water-cooled engine driving a tractor propeller. The first tailless aircraft was produced by J. W. Dunne in Scotland in 1911 and was successfully flown, After this the tailless aircraft was neglected until 1926, when Captain G. T. R. Hill produced his first tailless aeroplane. This first Pterodactyl was a single-seat light aeroplane driven by a pusher airscrew. The aileron controls of a Pterodactyl can be used in unison when it is desired to make the aircraft climb or dive. An American design of tailless aircraft has one semicircular wing in place
of two swept-back wings in the form of an arrowhead.
