According to plans, the spaceship then fires its rocket motor to catapult it to about 62 miles (100 km) above Earth, giving passengers a view of the planet set against the blackness of space and a few minutes of weightlessness.
The vehicle is based on a prototype, SpaceShipOne, which 10 years ago won the $10 million Ansari X Prize for becoming the first privately developed manned spacecraft to fly in space.
"During the test, the vehicle suffered a serious anomaly resulting in the loss of SpaceShipTwo," Virgin said in a statement just after the crash.
Witt said the first sign of a malfunction came 90 seconds to two minutes after the carrier jet released the spacecraft, which occurred at 10:10 a.m. local time.
"There's usually a certain cadence, and you see things occurring, and the thing makes a contrail and the like. Because of the very light cirrus clouds, I was eyes on, but I didn't see any anomaly. In fact it was when I wasn't hearing anything that I became concerned. And I looked over at my colleague, and then there was a radio call, something about a chute."
The crash was the second accident this week involving a commercial U.S. space company. On Tuesday, an Antares rocket built and launched by Orbital Sciences exploded after liftoff from Wallops Island, Virginia, destroying a cargo ship bound for the International Space Station.
Friday's crash marked a major setback for Virgin Galactic, a U.S. offshoot of billionaire Branson's London-based Virgin Group. The company was aiming to make the world's first commercial suborbital space flights with SpaceShipTwo, a six-passenger, two-pilot spacecraft.
The launch, which was controlled from the Mojave Air and Space Port, was to have been the first in a series of test flights leading up to Virgin Galactic's maiden flight beyond Earth's atmosphere.
Virgin ultimately was planning to add four more suborbital spacecraft to its fleet, along with a second White Knight carrier jet. Plans call for the fleet to fly out of a new space port in Las Cruces, New Mexico, once the company completes all test flights and is certified for passenger service to begin.
Virgin Galactic's Whitesides told a Toronto space conference earlier this month that a second spacecraft was already under construction and about 60 percent complete.
Other companies developing passenger suborbital spacecraft include privately owned XCOR Aerospace, which is building a two-person space plane called Lynx, and Blue Origin, a startup space company owned by Amazon.com Inc founder Jeff Bezos.
