SpaceshipTwo crashes during testflight
On 31st October 2014, Virgin galactic´s SpaceshipTwo crashed in the Mojave Desert,from the Mojave Air and Space Port in which it was dropped from the WhiteKnightTwo carrier aircraft, VMS Eve. The test flight was to include the first flight testing of a new, more powerful and steadier-thrust hybrid rocket engine whose binding agent was based on nylon instead of rubber.
SpaceShipTwo dropped from the mother ship and fired its new hybrid rocket engine normally. About eleven seconds later, the space plane violently broke apart, substantially giving the appearance of an explosion, and creating a 35-mile (56 km) long debris field. The co-pilot, Michael Alsbury, was killed in the crash, whereas the pilot, Peter Siebold, survived with serious injuries. Despite considerable early conjecture that the new rocket engine was at fault in the loss of VSS Enterprise, this was quickly discounted when the craft's engine and propellant tanks were recovered intact, indicating there was no explosion due to either the solid (nylon-based) or liquid (nitrous oxide) components of the hybrid engine.
A preliminary investigation and cockpit video subsequently indicated that the feathering system, the ship's air-braking descent device, deployed too early. Two seconds later, while still under rocket propulsion, the craft disintegrated. It is likely that a pilot error was the proximate cause of the crash.
