At 60 feet (18.3 meters) in length, Virgin Galactic's SpaceShipTwo is twice the size of the original SpaceShipOne. SpaceShipTwo contains six passenger seats and two pilot seats (the copilot is on hand to take over if the pilot is incapacitated). The cabin area has passenger windows much larger than those found on passenger jets, both at each seat and above, for use while floating in zero gravity.
