Federal investigators Mojave Desert last year, a passenger on the Virgin Galactic spaceship pilot as leading to the fatal accident, a subsidiary of the Northrop Grumman test pilots training was inadequate.
The National Transportation Safety Board on October 31, causing premature wrench open the fourth test flight powered ship's disintegration in the atmosphere depends on the Virgin Galactic SpaceShipTwo
US Transportation Security Administration is responsible for the accident on the scale Composites unit lying on Northrop Grumman developed the craft and crew work experience.
Space tourists to move out of the Earth's atmosphere for more than a decade old billionaire Richard Branson entreprenuer quest ate a push.
"A pilot of this type of failure is not considered that will stimulate, scaled," said principal investigator Lorenda Ward.
The NTSB is a test flight, the United States has agreed to recognize the potential dangers of non-commercial space flight, the Federal Aviation Administration, which oversees the criticism.
US Transportation Safety Authority, it is not enough to provide for the training sessions scaled in Washington, DC, during a hearing on the webcast section of the tail, pilot Peter Siebold, and over the last 10 years SpaceShipTwo off the crew and engineering staff members Michael Alsbury, including the pilot
The Air Force created the Authority put in place before the tail of the plane was stopped prematurely to understand what can happen when a child should be the training of its pilots.
"Flight procedures and the safety assessment of future projects will be reviewed to learn from this event, scaled," the NTSB hearing small Composites posted a statement said.
"Scaled document will expand training and testing along with a focus on the challenges inherent in rocket flight, to continue to improve security," the statement added.
Scalable design and Branson's Virgin Group and an affiliate of London-based Virgin Galactic for two pilots and six passengers of the vehicle.
Virgin, which is expected to last five planned fleet of vehicles used to transport passengers on board, up to semi-tropical short trips into space about 62 miles (100 km). The ride, which cost $ 250,000 apiece already sold about 700 tickets horses.
Virgin Galactic's new vessel is scheduled to begin before the end of the test flights.
The scale of SpaceShipOne, which began last year before the accident to take steps to create a transition Mojave-based spaceship company, Virgin is owned operation.
Siebold, 43, managed to parachute to safety when Alsbury, in fact, 39 years of experience, died in a pilot test. Each of the pilots working for small composites.
SpaceShipTwo vehicle, regardless of the orientation of the tail, the plane down to re-enter the atmosphere with heat-protected belly is designed to rotate.
Tail intent Mach 1.4, or about 1.4 times the speed of sound traveling in, the sound will be unlocked by one of the pilots of the fastest ships. Alsbury spacecraft was traveling at less than Mach 1 is part of the tail light.
The company is now open soon in order to prevent pilots from the tail section of the Virgin spaceships, said to be included.
The test flight came under the scale, and Virgin Galactic passenger service license and commercial space flight earlier in the FAA license.
