Here's some info from a BBC article about Rutan's SpaceShipTwo project.

SpaceShipTwo will not look anything like its predecessor. For one thing, Rutan must fix a stability problem caused by SpaceShipOne's high upswept wings.

For another, Rutan and Branson plan a ship of luxury, with service and amenities that at least match Virgin Atlantic's upper-class travel service. And that, as any airline flier knows, starts with leg room.

Rutan said SpaceShipTwo would have about the same diameter crew cabin as a Gulfstream V business jet, which measures slightly more than 6ft in height and 7ft in width (1.9m by 2.2m).

Seats will fully recline so that even elderly passengers - Rutan and Branson both plan to fly their elderly fathers - will be able to handle the expected force of six times Earth's gravity upon descent.

The G-forces are higher than what SpaceShipOne's pilot experienced, but that is because Rutan is aiming for a top altitude of between 84 and 87 miles (135-140 km), rather than the 62-mile (100km) target required to win the Ansari X-Prize competition.

The extra altitude will add about another 90 seconds of "weightlessness" for passengers to enjoy. Travellers will be able to do more than watch how candy flies around in space - they can fly themselves.
