Channel in a heavier-than-air aircraft, on 25 July 1909. This is one of the most
a lasting place in history but also assured the future of his aircraft
manufacturing business. The event caused a major reappraisal of the importance
of aviation; the English newspaper The Daily Express led its story of the flight
with the headline "Britain is no longer an Island".
It was produced in both single- and two-seat versions, powered by a number of
different engines, and was widely used for competition and training purposes.
Military versions were bought by many countries, continuing in service until
are thought to be the two oldest flyable aircraft in the world.
predecessor, it was a tractor-configuration monoplane with a partially covered
box-girder fuselage built from ash with wire cross bracing. The principal
difference was the use of wing warping for lateral control. The tail surfaces
consisted of a small balanced "all-moving" rudder mounted on the rearmost
vertical member of the fuselage and a horizontal tailplane mounted under the
lower longerons. This had elevator surfaces making up the outermost part of the
fixed horizontal surface; these "tip elevators" were linked by a torque tube
running through the inner section. The bracing and warping wires were attached
to a dorsal, five-component "house-roof" shaped cabane consisting of a pair of
inverted V struts with their apices connected by a longitudinal tube, and an
inverted four-sided pyramidal ventral cabane, also of steel tubing, below. When
first built it had a wingspan of 7 m (23 ft) and a small teardrop-shaped fin
mounted on the cabane, which was later removed.
Like its predecessor, it had the engine mounted directly in front of the leading
edge of the wing and the main undercarriage was also like that of the Type VIII,
with the wheels mounted in castering trailing arms which could slide up and down
steel tubes, the movement being sprung by bungee cords. This simple and
ingenious design allowed crosswind landings with less risk of damage. A sprung
tailwheel was fitted to the rear fuselage in front of the tailplane, with a
similar castering arrangement.

The aircraft, which never flew again, was hurriedly repaired and put on display
at Selfridges department store in London. It was later displayed outside the
offices of the French newspaper Le Matin and eventually bought by the Musee des
Arts et Metiers in Paris.
After the successful crossing of the English Channel, there was a great demand
