It's interesting that all of you "experts" didn't know that the plane is based on an already successful rocket launch vehicle called WhiteKnightOne. The WhiteKnightOne sucessfully launched SpaceShipOne.
Paul Allen won the Ansari X-Prize with that vehicle.

The
Ansari X Prize was a
space competition in which the
X Prize Foundation offered a
US$10,000,000
prize for the first
non-government organization to launch a reusable
manned spacecraft into
space twice within two weeks. It was modeled after early 20th-century
aviation prizes, and aimed to spur development of low-cost spaceflight.
Created in May 1996 and initially called just the "X Prize", it was renamed the "Ansari X Prize" on May 6, 2004 following a multimillion-dollar
donation from
entrepreneurs Anousheh Ansari and
Amir Ansari.
The prize was won on October 4, 2004, the 47th anniversary of the
Sputnik 1 launch, by the
Tier One project designed by
Burt Rutan and financed by Microsoft co-founder
Paul Allen, using the experimental
spaceplaneSpaceShipOne.
