After doing our best to take care of the families and each other, the first order of business was to work with Cal OSHA in its investigation of the accident. In certain instances, an amended return showing a reduction of tax may be treated by DOR as an application for abatement. The investigation is the NTSB's first into a commercial space accident. “We do understand the risks involved, and we’re not going to push on blindly.” He added that anyone who had already signed up for a Virgin Galactic flight and wanted a refund would get one. The test included filling the oxidizer tank with 4,500 kg (9,900 lb) of nitrous oxide , … “It's not been a good week,” astronaut Leroy Chiao told US news channel CNN.

Like its predecessor, SpaceShipTwo is carried to launch altitude by a jet-powered aeroplane, then detaches itself and fires its rocket engines to gain height. More news releases and status reports or top stories. Next along the trajectory was the cockpit, and finally to the southwest was the engine. It should go without saying that we were completely surprised by this accident, as we had conducted numerous tests, without incident, on similar systems including the SpaceShipOne rocket motor. A second SpaceShipTwo has been under construction. It is not clear how Siebold managed to get out of the plane. On 26 July 2007, during the early vehicle subsystem testing phase, an explosion occurred during a propellant flow test by Scaled Composites at the Mojave Air and Space Port.
