After taking off attached to the company's carrier plane WhiteKnightTwo, VSS Unity rocketed to an altitude of 82 kilometres (51 miles) before cruising back to ground in a gliding descent.

The spacecraft SpaceShipTwo company Virgin Galactic has performed a fourth test flight and set a world record. We started Virgin almost 50 years ago dreaming big and loving a challenge.
Bezos' New Shepard has already flown to the internationally recognized boundary between Earth's atmosphere and outer space known as the Karman line at 62 miles (100 km) - though the Blue Origin trip did not carry humans.
The spaceship then ignited its engines and continued traveling at about 3 times the speed of sound.
At the start of the test flight, a special jet carrying the Virgin Space Ship Unity flew to an altitude near 43,000 feet (13,100 meters) before releasing the craft.More news: Mauricio Pochettino's true feelings on United vacancy following Mourinho's departure

Virgin Galactic considers that altitude to be the threshold of space because it's defined that way by the Air Force and other US agencies, although others have long considered the boundary to be higher. Virgin celebrated the vessel's first encounter with space, but the company is using the loosest definition of "space".
The next flight test is expected within the next couple of months, depending on data analysis from Thursday's flight, Virgin Galactic said.
The company plans to eventually take paying passengers on short trips to space.More news: Deepika recalls first meeting with Ranveer: dating someone else, flirting with me
After arriving back at the test centre, the co-pilot, Mr Stucky, said: "It was a great flight". CSF President Eric Stallmer said the "commercial space industry will create unprecedented opportunities for space tourism and democratize space for all". Virgin's researchers are, however, favouring the lower figure as a more accurate representation. Just recently, NASA concluded that astronaut Nick Hague made a spaceflight on Soyuz MS-10 even though the flight was aborted about two minutes after liftoff and did not attain orbit. The crew capsule reached 93 kilometers altitude, however NASA's statement was that it counts it as a spaceflight for Hague and his Russian crew mate Aleksey Ovchinin because they "launched and landed in a spacecraft or an intended mission to the International Space Station" without mentioning any altitude.
