SS2 Delay

Jeff Foust talked to Burt Rutan at yesterday's rollout.

Rutan confirmed that the investigation was causing "a lot" of design changes for SS2. "We have not worked on SpaceShipTwo in a year," he said, "because there's a possibility that the propulsion system would be markedly different and we'd be building things that we would have to scrap."

So they've essentially lost a year due to the accident. I wonder if they'll finally switch over to a liquid system? It would save them quite a bit in ops costs, I'd think.
