Initially, Clements' powers include superhuman speed, invulnerability, and levitation.
Tractor wheels may lift off the track in when the vertical g-force is zero or negative, but the up-stop wheels keep the train from coming completely off the rails.
With an "open architecture" design and explicit plans for multi-purpose use, the aircraft could also operate as a zero-g aircraft for passenger training or microgravity science flights, handle missions in high-altitude testing more generally, or be used to launch payloads other than SpaceShipTwo.
Shattered Horizon is a first-person shooter where players fight in zero gravity surrounded by the broken remains of Earth's orbital infrastructure and billions of tons of rocky debris thrown into orbit by a huge explosion on the Moon.
In 2013, Spaceport Sweden initiated a limited offering of weightless flight experiences, in collaboration with AirZeroG and Novespace in France, to private individuals using a specially outfitted Airbus A300 capable of simulating a short-duration zero-gravity environment.
Multiple extra modes are available after completion of the early operations, such as performing an operation while inside an ambulance where surgical instruments bounce around at random, and operating in space where the zero-g environment causes all the instruments to free-float.
The conducted experiments, supervised by Dutch astronaut Wubbo Ockels, on the capillarity effect under weightlessness conditions, proved feasible to grow plants in Lunar soil.
EXA had tested microgravity via parabolic flight with the Ecuadorian Air Force and Space Adventures.
The show saw May interviewing Apollo moonwalkers Harrison Schmitt, Alan Bean, and Charlie Duke, before himself experiencing weightlessness and G-forces similar to that of a Saturn V rocket launch.
