Due to technical difficulties I have been unable to blog live but a video recording of the key part of the press conference will be available later today
However I can report that;
Burt Rutan, looking frail after a recent illness, said that they still did not know what caused the accident at Scaled’s facility last July but they were working with Californian authorities and aerospace consultants to find out. Once a cause was found that would be published.
Talking about the twin-fuselage White Knight II (WKII) the aircraft, when not carrying SpaceShipTwo, can make a 6g descending wind up turn and that can be used to give passengers g training prior to their flights. Using parabolic flight the WKII will also simulate weightlessness for a few seconds
Burt Rutan said that on reentry passengers will experience 4g and above for 20s and that the build up from microgravity to 1g will be 20-25s.
More soon, including that video
