Rocket propulsion expert Carolynne Campbell-Knight has told Virgin boss Richard Branson “go away and do something they might be good at like selling mobile phones” following the crash of SpaceShipTwo.
Campbell-Knight,who is a lead rocket propulsion expert for the Netherlands-based International Association for the Advancement of Space Safety (IAASS), has said that she had warned Virgin Galactic before about using nitrous oxide in its propulsion system because it could "go bang in a very unpredictable way".
The crash saw test pilot Mike Alsbury die.
She added that the company “should stay out of the space business” and suggested that they “stop, give up”.
Despite these words, others have praised Branson for how he handled the crisis.
