NTSB: Uncommanded Feather of SpaceShipTwo

NTSB Releases New Clues in SpaceShipTwo Accident Investigation (with video), SpaceRef

"Acting Chairman Christopher Hart's of the National Transportation Safety Board (NTSB) released new clues at the third media briefing Sunday evening.
1) The vehicle had a nominal release followed by a nominal Ignition.
2) Approximately 9 seconds after ignition, the "feather" parameters changed from lock to unlock.
According to Hart the "normal procedures are to command the feathers to unlock after Mach 1.4 so aerodynamic forces do not extend feathers prematurely."
