So When Will It Fly?

Cosmic Log’s Alan Boyle has an interesting interview with Scaled Composites’ Burt Rutan on progress developing SpaceShipTwo. Rutan expects to build 40-45 of the vehicles over the next dozen years with the aim of flying about 100,000 on suborbital hops.

Rutan also says the company does still not know the cause of the explosion that killed three employees last summer. California safety officials issued citations totaling $25,000 for safety violations at the Mojave facility.
