A milestone for private space flight

The Virgin Galactic spaceplane, a SpaceShipTwo model named Unity, designed for carrying tourists on suborbital flights, had it fastest and highest flight yet, reaching an altitude of 82 km (271,268 feet).    Congratulations! 

Here's a good video clip.
It's pretty awesome to think about this. A private company, with no government support, built a spaceplane that goes higher and faster than any such craft built by any government in the world, with the sole exception of the X-15, of the 1960s, which was also air-launched.  (NASA did put four experiments on board.) The SpaceShipTwo craft carried a crew of two pilots and a mannequin representing a passenger.

Now, was it "in space?" Depends on your definition.  There is no international agreement setting the boundary between air and space.  The US Air Force has always used 50 miles above sea level as the basis for awarding astronaut wings.  The FAA picked up that definition: astronaut wings are on the way for the pilots.  Most authorities on spaceflight point to the von Karman line, 100km (62 miles) as the boundary. 

For Virgin Galactic, which has 600 people signed up to fly at a quarter of a million dollars each, they made it. 

The press release stated, in part: "The historic achievement has been recognised by the Federal Aviation Administration (FAA) who announced today that early next year they will present pilots Mark "Forger" Stucky and Frederick "CJ" Sturckow with FAA Commercial Astronaut Wings at a ceremony in Washington DC. CJ, as a four-time Space Shuttle pilot, will become the only person to have been awarded NASA and FAA wings."

Oh, and the passengers could theoretically toast with champagne. The French (who else?) have designed and tested a champagne bottle under spaceflight conditions.
