Virgin Galactic just came much closer to resuming its dreams of private spaceflight in the wake of its tragic crash from 2014. The company has successfully conducted the first glide test flight for VSS Unity, better known as the new SpaceShipTwo. The vehicle was only flying free for 10 minutes and never traveled faster than Mach 0.6, but that was enough to get a healthy amount of data illustrating how Unity behaves in real life.
