SpaceShipTwo successfully completed an unpowered glide test yesterday, testing the dynamics and plumbing of the ship’s new engines.
They pumped inert liquid through the plumbing to make sure it functioned in flight. The flight itself tested the balance and position of the new engine.
Assuming the results from these tests are good, expect powered flights quite soon.
