Sometime in the 1940s, Wright biographer, Men with a vision who changed the worldFred C. Kelly, asked Orville: "What was the most exciting part of inventing the flying machine? Was it when the machine took to the air for that first flight?" Orville thought for a moment and then replied: "The most exciting part of inventing the flying machine was lying awake in bed at night dreaming of how exciting it would be to fly."
Barely 66 years after the Wright Brothers' first steps into air, Neil Armstrong and Buz Aldrin stepped onto the surface of the moon to complete another chapter in the grand adventure. Today, only 100 years after the Flyer, spacefight is becoming routine and unmanned vehicles are probing deep into the universe, preparing the way for manned fights to distant worlds.
