1845-48-William Samuel Henson and John Stringfellow attempt to form the Aerial Transit Company, which (if only they had a practical airplane), would have been the world's first airline. To drum up support, they build and test a model of Henson's aerial carriage with a 20-foot wingspan. It makes brief glides, but does not sustain flight.
1849-Sir George Cayley builds a small glider designed to lift about 80 pounds of the ground. He refers to it as his Boy Glider. It is the first recorded manned (or boyed) fixed-wing aircraft. It lifts a 10-year old boy off the ground for a few yards on test runs. Cayley also flew it in a high wind like a kite, tethered to the ground.
