Samuel Johnson’s 1759 novel Rasselas contains a remarkable passage — he anticipates the airplane by nearly 150 years:

He that can swim needs not despair to fly; to swim is to fly in a grosser fluid, and to fly is to swim in a subtler: We are only to proportion our power of resistance to the different density of the matter through which we are to pass: You will be necessarily upborne by the air, if you can renew any impulse upon it, faster than the air can recede from the pressure.

“As a basic claim for a modern patent, the statement could not be broader nor more comprehensive,” wrote a correspondent to U.S. Air Service in 1920. “It only required the modern high-powered internal combustion engine to render his claim effective.”
