“Now widely regarded as 'The Father of Aeronautics', Sir George Cayley (1773-1857) evolved the idea of an aircraft with fixed wings, in which the principle of lift was separated from the propulsion system, and in which inherent stability, as well as tail-unit control-surfaces, must be incorporated.”--Royal Aeronautical Society website intro to Cayley.

[William S. Henson, 1812-1888] "On the Steam Power of Mr. Henson's Flying Machine", pp 281-2, with 4 text illustrations. "The aerial steam carriage, also named Ariel, was a flying machine patented in 1842 that was supposed to carry passengers into the air. It was, in practice, incapable of flight since it had insufficient power from its heavy steam engine to fly. A more successful model was built in 1848 which was able to fly for small distances within a hangar. The aerial steam carriage was significant because it was a transition from glider experimentation to powered flight experimentation."--Wikipedia
