24 September 1852: French engineer Baptiste Henri Jacques Giffard (1825–1882 ) flew his hydrogen-filled dirigible, powered be a 3-horsepower steam engine, 17 miles (27 kilometers) from the Paris Hippodrome to Trappes in about three hours. During the flight he maneuvered the airship, demonstrating control.

The Giffard Dirigible (French: “directable”) consisted of an envelope 44.00 meters (144 feet, 4 inches) in length, 10 meters (32 feet, 10 inches) in diameter, and had a volume of 2,500 cubic meters (88,300 cubic feet). The envelope was filled with coal gas. A one-cylinder steam engine fueled with coke turned a 3.3-meter (10 feet, 10 inches) diameter, three-bladed pusher propeller mounted to the underslung gondola. The steam engine weighed just 250 pounds (113 kilograms), and with the boiler and fuel, came to 400 pounds (181 kilograms).
