Virgin Galactic completed what's expected to be its final test flight Thursday before taking paying customers on brief trips to space.
Six of the company's employees, including two pilots, landed at Spaceport America in southern New Mexico after the short up-and-down flight that included a few minutes of weightlessness. It took about an hour for the mother ship to carry the spaceplane to an altitude where it could fire its rocket and make the final push to the edge of space.
