Virgin Galactic just passed another milestone.
A Virgin Galactic spaceship meant to shuttle tourists into space blasted through the sound barrier in its latest supersonic test flight Thursday, soaring to 69,000 feet above the planet and reaching a maximum speed of Mach 1.43 before drifting back safely to Earth.
Started in 2004, Galactic is the space-bound side of Sir Richard Branson's juggernaut travel company Virgin Airlines.
Galactic's goal is to provide space flights for $200,000 a pop to regular, everyday earthlings who want to see what's usually reserved for highly trained astronauts.
