Hart said test flights are usually well-documented. Investigators will review video from multiple cameras that were on the spaceship, on the mother ship, on a chase aircraft and at nearby Edwards Air Force Base. They also have six “nonvolatile” sources of information from the aircraft, and radar data to sift through, he said.
The investigation could take up to 12 months to complete, he said.
Virgin Galactic—owned by Branson's Virgin Group and Aabar Investments PJS of Abu Dhabi—plans to fly passengers to altitudes more than 62 miles above Earth. The company sells seats on each prospective journey for $250,000.
The company says that “future astronauts,” as it calls customers, include Stephen Hawking, Justin Bieber, Ashton Kutcher and Russell Brand. The company reports receiving $90 million from about 700 prospective passengers.
On Saturday, Branson said none of that money has been spent and that anyone who wanted a refund could get it. However, he said, no one has asked, and instead someone signed up on the day of the accident in a show of support.
At 60 feet long, SpaceShipTwo featured two large windows for each of up to six passengers, one on the side and one overhead. Branson once envisioned operating flights by 2007. Last month, he talked about the first flight being next spring with his son.
