"Our investigation just covers this case from a safety in the workplace perspective. When cases close, we then refer them to the district attorney's office to assess whether there are any criminal or civil issues involved. That usually takes months, at least six months. It depends on [CAL-OSHA's] workload, the complexity of the case, a lot of variables," says Cal-OSHA.
Virgin Galactic expects Scaled Composites to roll out its SpaceShipTwo (SS2) carrier aircraft White Knight II (WK2) in early May for ground tests.
Construction of the four-engine, twin-fuselage prototype is 80% complete at Scaled's Mojave, California facility, said Virgin Galactic at the New York unveiling of SS2 and WK2 on 23 January.
Because the WK2's two fuselages will share a common cabin design with the SS2 suborbital vehicle, the carrier aircraft will be used for pilot and passenger training for the spaceship's flights.

With all the issues and legal 'junk" going on about the explosion of SS2's propulsion system and the fact that its development is on hold would lead me to believe/guess that we are probably going to have to wait for SS2s first flight till early 09. WK2 thou will fly this year in the summer and that its-self will be fairly interesting for all I'm sure.
Work on the propulsion program remains on hold at the moment, with future plans uncertain, but work in other areas, such as the carrier aircraft, continue
We are having delays in the rocket engine development. We just don't know how long they will be.

What would be the limitations? Anything other than missiles gone orbital plane dropped? How much do you think the concept can be scaled up before materials limits are approached particularly from the drop plane?

SpaceDev helped develop and build SpaceShipOne's "hybrid" motor, which burned liquid laughing gas and solid rubber. He says the company had to scale the motor's thrust up by a factor of 1000 to prepare for the SpaceShipOne flights.
To get to Mach 25, it has to scale up its most powerful motor by only a factor of four - to provide a total of about 454,000 kilograms of thrust. "It's not that difficult," he says.
Investigation of the accident at Scaled Composites in California on 26 July 2007 suggests the oxidiser tank for the propulsion system under development for Virgin Galactic's SpaceShipTwo suborbital rocket was the origin of the nitrous oxide explosion that killed three employees.....
"The workers had transferred the nitrous oxide from the [mobile conditioning system] into the propulsion equipment apparatus tank mounted on the test stand. The catastrophic explosion occured about 3s after the [cold nitrous oxide] flow began," says the summary, published on 7 February.
