Heard this morning of the explosion and crash of Spaceship 2 during a test flight. Reports on various news channels advise of the loss of life of the co-test pilot and the test pilot being seriously injured. Egressing Spaceship 2 must be very difficult in a emergency and I'm sure impossible at some stages of the flight envelope. Same reports advise of a explosion just after release from the mother-ship during rocket engine ignition and that this flight was testing a new propellant mix. This rocket engine is much like the SRB's used on the Shuttle - like Chinese skyrockets, once lit there is no stopping them until exhausted of the solid propellant.
We will no doubt in time hear the results of the thorough investigation already in progress. This will no doubt delay flights with the paying passengers and of course rightly so. The airspace over the Mojave high desert once again claimed the life of a very talented test pilot.
I guess this just re-enforces that fact that there is nothing "routine" about space flight - government funded or in private venture. This is flight right on the edge in terms of performance, altitude, material research and testing. My thoughts go out to the family and friends of the victims of this accident.
