Sir Hiram Maxim's Flying Machine. Opened in August 1904, Sir Hiram Maxim's Flying Machine is the only surviving captive flying machine ride in the world and is Pleasure Beach's oldest ride. A steel pole, 62 feet high, supports 10 arms from which hang carriages, creating an illusion of flying. Designed by Sir Hiram Maxim to raise money for his attempts to be the first man to fly the measured mile.
