The mother ship, SpaceShipOne, has been seen before and speculation that it was built to win the X prize has been rife. This is the official confirmation, and the first shot I've seen of the second stage vehicle, White Knight. And if anyone can deliver, Rutan can. 
"Scaled Composites…is tired of waiting for others to provide affordable human space access," Rutan said.....
"The event is not about dreams, predictions or mockups," Rutan explained in a pre-debut statement. "We will show actual flight hardware: an aircraft for high-altitude airborne launch, a flight-ready manned spaceship, a new, ground-tested rocket propulsion system and much more. This is not just the development of another research aircraft, but a complete manned space program with all its support elements," he said. "We are not seeking funding and are not selling anything. We are in the middle of an important research program…to see if manned space access can be done by other than the expensive government programs," Rutan explained.
Rutan said that after today, plans call for his group to go "back into hiding," to complete the flight tests and conduct the space flights....
To win the X Prize, private teams must finance, build and fly a three-person spacecraft 62 miles (100 km) to the edge of space, return safely, and then demonstrate the reusability of their vehicle by flying it again within two-weeks. The goal of the St. Louis, Missouri-based X Prize Foundation is to make space travel frequent and affordable for the general public.
