The first few trips to space will be flown by test pilots without anyone else on board. Branson says he will be the first passenger. Eventually, paying tourists will also make the trip. "I'm not allowed up until the [test pilots] have broken it in a few times, first," he said. "I would love to have gone on this very [first] flight, but [pilots] are incredibly brave people." SpaceShipTwo, Galactic's rocket-powered plane, will fly into space after it detaches from beneath the wing of a mothership. It has been thoroughly tested on the ground and at lower altitudes, Branson said. But, the first few flights to space will be "the dangerous ones."
