Sir George Cayley, also called Sir George Cayley, 6th Baronet, (born December 27, 1773, Scarborough, Yorkshire, England—died December 8, 1854, Brompton, Yorkshire), English pioneer of aerial navigation and aeronautical engineering and designer of the first successful glider to carry a human being aloft.
Cayley is mainly remembered for his pioneering studies and experiments with flying machines, including the working, piloted glider that he designed and built. He wrote a landmark three-part treatise titled "On Aerial Navigation" (1809–1810),  which was published in Nicholson 's Journal of Natural Philosophy, Chemistry and the Arts.

Sir George Cayley, 6th Baronet (27 December 1773 – 15 December 1857) was an English engineer, inventor, and aviator. He is one of the most important people in the history of aeronautics. Many consider him to be the first true scientific aerial investigator and the first person to understand the underlying principles and forces of flight.
Dec 9, 2022 · Cayley did not pilot his prototype gliders himself; he left that duty in one case to a 10-year-old boy and in another to his coachman. But he was the first person to identify the four-vector forces that influence an aircraft: thrust, lift, drag, and weight.
Oct 28, 2019 · An elderly gentleman, Sir George Cayley, was making the final adjustments to his flying machine, a glider, in preparation for launching a grown man into the air. According to the account of Cayley’s granddaughter, the somewhat reluctant pilot-passenger was a coachman, John Appleby.
George Cayley's 1804 glider design. By 1808, Cayley had constructed a glider with a wing area of almost 300 square feet (28 square meters). By the middle of 1809, Cayley had investigated the improved lifting capacities of cambered wings, the movement of the center of pressure, longitudinal stability, and the concept of streamlining.
Jan 6, 2014 · Cayley did most of his work on flying machines around the turn of the 19th century, 100 years before the Wright brothers. At the time, there was no engine light enough or powerful enough to get a vehicle airborne, so Cayley’s most significant inventions were unpowered gliders.
