The shuttles rendezvoused and started to accelerate toward the ground.

The shuttle to Georgetown didn't start for another hour.

The shuttles bringing the research and development team started to arrive while breakfast was in progress.

The station was first proposed in 1984, shortly after the shuttles started traveling into space.

At once, the shuttle started to shake much more violently than it had in the descent so far.

Daak continued to grin, but he must have noticed: the shuttle started to turn.

Porter tapped her panel, and the shuttle started to move slowly forward toward the growing gap.

"It could have been in that condition before the shuttle ever started re-entry," he added.

"Let's get this shuttle started and get out of here."

A door in the outer surface of the sphere opened and the shuttle started to enter.
