Joke

Who made this bad prediction?

"The popular mind often pictures gigantic flying machines speeding across the Atlantic and carrying innumerable passengers in a way analogous to our modern steamships…It seems safe to say that such ideas must be wholly visionary, and even if a machine could get across with one or two passengers the expense would be prohibitive to any but he capitalist who could own his own yacht. Another popular fallacy is to expect enormous speed to be obtained. It must be remembered that the resistance of the air increases as the square of the speed and the work as the cube...If with 30 horsepower we can now attain a speed of 40 miles per hour, then in order to reach a speed of 100 miles per hour we must use a motor capable of 470 horsepower...It is clear what with our present devices there is no hope of competing for racing speed with either our locomotives or our automobiles."
