Not content with breaking its own previous altitude records, an incredible video of Virgin Galactic's SpaceShipTwo reveals the latest test flight also managed to smash through the sound barrier.
The video, taken by cameras placed on carrier plane WhiteKnightTwo, show SpaceShipTwo reaching its maximum velocity of Mach 1.4, approximately 767mph at sea level. Any speeds faster than Mach 1 are considered supersonic.
The test at Mojave Air and and Space Port in California was designed to simulate a flight into outer space that will go into effect later this year.

'2014 will be the year when we will finally put our beautiful spaceship in her natural environment of space. Today, we had our own Chief Pilot flying another flawless supersonic flight and proving the various systems required to take us safely to space, as well as providing the very best experience while we’re up there,' said Virgin CEO Richard Branson.
Celebrities have already started signing up for the exclusive space tours ready to take off later this year. NBC reports that Katy Perry and Justin Bieber have already signed up. Tickets cost $250,000 (£152,000).
CEO Richard Branson has promised to take a seat on the ship's first flight. Branson hopes to move the passenger flight base to Spaceport America in New Mexico.
