Branson spaceship explosion: The 'missed' warnings
http://www.telegraph.co.uk/news/worldnews/northamerica/usa/11203634/Branson-spaceship-explosion-The-missed-warnings.html

"A number of senior aerospace engineers repeatedly voiced fears over
the design of Sir Richard’s SpaceShipTwo and the safety protocols
surrounding its testing.

The Telegraph has seen emails and other documents in the public domain
dating back several years, and as recently as last year in which
the engineers warned of the dangers of Virgin Galactic’s rocket
engine system.

It also emerged on Saturday that three senior Virgin Galactic
executives the vice-president in charge of propulsion, the
vice-president in charge of safety, and the chief aerodynamics
engineer had all quit the company in recent months. "

"The Telegraph can disclose that Sir Richard’s company, as well as US
authorities, were warned about safety issues on numerous occasions, as
long ago as 2007 when three engineers died in an explosion during
testing of a rocket engine on the ground.

Carolynne Campbell, the lead expert on rocket propulsion at the
International Association for the Advancement of Space Safety (IAASS),
said: “This explosion is not a surprise. None whatsoever, I am sorry
to say. It is exactly what I was expecting. It was Russian roulette
which test flight blew up.”

She had first warned Virgin Galactic about the danger of its nitrous
oxide-propelled engines in the aftermath of the 2007 disaster, and has
repeated those warnings since. "
