Virgin Galactic SpaceShipTwo suffered 'serious anomaly' during crash

The Virgin Galactic SpaceShipTwo suffered a "serious anomaly" during a test flight in California over the Mojave desert, with one pilot killed in the incident. The other pilot suffered serious injuries and is being transported to the hospital, according to the company.

"The WhiteKnightTwo carrier aircraft landed safely," said Virgin Galactic after the incident. "We will work closely with relevant authorities to determine the cause of this accident and provide updates ASAP."

The SpaceShipTwo is designed to be carried on a mother ship and then can be released to ignite its rocket to head into suborbit, and can return to Earth by gliding back. A flight starts at $250,000 and passengers undergo three days of pre-flight preparation to verify they are physically and mentally prepared for the trip.
