Today we think of Sir George Cayley, 6th baronet, as a pioneer of flight. His family may well have regarded his construction of flying machines as an expensive eccentricity. After his death, the flying machine which flew a few hundred yards (with a startled coachman inside, who is said to have given his notice as soon as he landed) in 1853 was tucked away in a barn on the Brompton estate.
One of his granddaughters, Dora Cayley (a daughter of Sir Digby, the 7th baronet), told a cousin how, in her childhood, she used to sit in the glider when she wanted to hide from her governess. Unwanted flying machines have their uses!
