Virgin Galactic's Successful Space Tourism Test Flight.

Virgin Galactic successfully completed a test flight of its space plane, VSS Unity, carrying two pilots and four crew members to the edge of space. The flight is a crucial step towards opening up rides to paying customers in late June. The company hopes this will be the final test run, but any major issues could throw Virgin Galactic's future into question or lead to more delays. The flight is designed to reach more than 50 miles above Earth, into altitudes recognized as the boundary of outer space by the US government.
