"Virgin Galactic's SpaceShipTwo could be a single stage to suborbit
vehicle using liquid chemical propulsion according to independent
research carried out by a company that has been contracted by the
European Space Agency for suborbital and hypersonic transport
studies."
"... the UK firm came to the conclusion that the volume within which
SS2 carries its solid rocket motor and nitrous oxide supply could
equally hold a liquid chemical propulsion system capable of providing
enough thrust for long enough for a horizontal take-off and ascent to
50,000ft and above without the need for WK2."

If you also filled up the passenger compartment with fuel leaving only
a pilot's cabin could it even become orbital?
