A blog post by Virgin Galactic on the test flight said: "Today is another historic day for Virgin Galactic. The team have carried out our second powered test flight, once again breaking the sound barrier and heading closer and closer to the stars. "This is a giant step. Our spaceship is now the highest commercial winged vehicle in history! We also successfully tested its feather system for carefree re-entry too - the first time that’s happened on a rocket powered flight."
