The middle"hull" is actually Spaceship Two. The Mothership, White Knight Two carries it to a great altitude, then it drops away and ignites a powerfull rocket, made from used tires of all things, and flies up to LEO (Low Earth Orbit). When it comes time to return to Earth, it does what's called a "Falling Leaf" maneuver, tipping to tail/wings into the vertical relative to the hull, and drifting slowly into the atmosphere, thus eliminating re-entry heat and it's concerns. Once the craft reaches thick enough air, around 50-60kft I believe, the tail/wing assemble returns to it's "regular" flight position, as seen here, and the craft glides to a landing, in a much more controllable, and slower speed than the shuttle.
All of this is NOT conjecture. It's been done. Two orbital insertions and, after several orbits, two returns (not exactly re-entry as most think of it). All done in the space of, now wait for it....TWO DAYS. All it needed for a turnaround was a replacement of the rocket motor, and replenishment of the oxygen. Let's see NaySay do THAT with their badly out-of-date shuttle. They can't even get it to the friggen Assembly Building in a day...
Both White Knight and Spaceship Two are made from carbon fiber composites, and their computer and instrument systems are all off the shelf, and thus quickly and easily upgradable. Again, let's see NaySay do that! And the costs, while pretty high, are nowhere near the multibillions NaySay uses.
Virgin Galactic is a long-delayed first step into a new world, and a vital one to Human Survival! All this sort of thing should have been the focus of NaySay since we landed on the Moon, not their buerocratic spending of huge monies for no return.
Just a little blurb, sorry. But to answer the original question: Not nearly as much as I'd spend to go up in Spaceship Two! I'd mortgage my SOUL to do that, even just once...

Have fun, fly high, far, and free!
