Vulcan’s concept is that this airplane will carry a rocket weighing up to 275 tons slung beneath the central part of the wing — between the two fuselages — and release it at 35,000 feet. The rocket will then launch into space and deliver satellites into orbit.

Unlike today’s massive Atlas and Delta rockets that launch vertically from Earth, the Roc will be able to land, load up and take off again, making space access easier and cheaper. It’s supposed to be more like a routine airport operation than a big Cape Canaveral-style deal.

“When such access to space is routine, innovation will accelerate in ways beyond what we can currently imagine,” Allen said in an emailed statement.

So he's just developing a rocket launcher for the fun of it?!
