===Overview of the flights to be developed===
The spacecraft initially called [[SpaceShipTwo]] was planned to achieve a [[Sub-orbital spaceflight|suborbital]] journey with a short period of weightlessness. Carried to about 16 kilometers, or 52,000&nbsp;ft, underneath a carrier aircraft, [[Scaled Composites White Knight Two|White Knight Two]], after separation the vehicle was to continue to over 100&nbsp;km (the [[Kármán line]], a common definition of where "space" begins). The time from liftoff of the White Knight Two mothership carrying SpaceShipTwo until the touchdown of the spacecraft after the suborbital flight would be about 2.5 hours. The suborbital flight itself would be only a small fraction of that time, with weightlessness lasting approximately 6 minutes.<ref name="Shatner2">{{cite web |title=Captain Kirk signs on for Virgin Galactic Space Ride |url=http://www.soultek.com/space_privatization/Virgin_Galactic_Captain_Kirk_and_spaceshipone.htm |publisher=soultek.com|access-date=14 February 2008 |archive-url=https://web.archive.org/web/20070929175813/http://www.soultek.com/space_privatization/Virgin_Galactic_Captain_Kirk_and_spaceshipone.htm |archive-date=29 September 2007 |url-status=dead |df=mdy-all}}</ref> Passengers were to be able to release themselves from their seats during these six minutes and float around the cabin.
