SpaceShipTwo is a winged plane with a single rocket motor developed by Virgin Galactic. The plane is attached to the underside of a twin-fuselage mothership known as WhiteKnightTwo. Once released, the space plane accelerates rapidly – with up to three Gs of force.
On 11 July 2021, the SpaceShipTwo VSS Unity made a successful, crewed suborbital flight to 86 km above the Earth before making a runway landing.
