Rutan has said that ideas about the project began as early as 1994. The full-time work towards the 2004 accomplishments took about three years. The vehicle first flew faster than the speed of sound on December 17, 2003. This date was also the one-hundredth anniversary of the Wright Brothers' historic first powered flight. SpaceShipOne's first official spaceflight, was piloted by Mike Melvill. A few days before that flight, the Mojave Air and Space Port was the first commercial spaceport licensed in the United States. A few hours after that flight, Melvill became the first licensed U.S. commercial astronaut. The overall project name was "Tier One". It has evolved into Tier 1b with a goal of taking a new, but similar ship's first paying passengers into space within the next few years.
