WhiteKnight 2, the plane (mothership?) that will eventually deploy SpaceShip 2 and a couple lucky guests into the outer reaches of our atmosphere, appears to be in a very functional state. That's a beneficial quality when you're flying around in it as the crew was on the 28th of July during the Oshkosh air show.
The interior isn't much different than what you're used to seeing in newer aircraft. All-LCD, although still decked out with toggles and buttons galore.
