The surviving co-pilot of the Virgin Galactic crash was unaware that SpaceShipTwo’s re-entry system was unlocked prematurely during the flight test, according to an update from the National Transportation Safety Board.
In an interview with investigators, the board said Peter Siebold provided testimony that was consistent with other information gathered so far since the crash. The incident, which killed fellow co-pilot Mike Alsbury when the craft plunged into the Mojave desert, took place Oct. 31.
“The NTSB operations and human performance investigators interviewed the surviving pilot on Friday. According to the pilot, he was unaware that the feather system had been unlocked early by the copilot,” read an update on the board’s website.
“His description of the vehicle motion was consistent with other data sources in the investigation. He stated that he was extracted from the vehicle as a result of the break-up sequence and unbuckled from his seat at some point before the parachute deployed automatically.”
Accidents are due to a complex set of circumstances, which means the NTSB finding that the re-entry system was deployed prematurely is only a preliminary finding. The investigation into the full circumstances surrounding the crash could take anywhere from months to a year, according to multiple media reports.
Virgin was performing another in a series of high-altitude test flights in preparation for running tourists up to suborbital space early next year. A handful of ticket-holders, who made deposits of up to $250,000 each, have reportedly asked for their money back. The Richard Branson-founded company has not revealed when the first commercial flight is expected to take place.
Meanwhile, Virgin does have another version of SpaceShipTwo already under assembly right now, which is considered 95% structurally complete and 60% assembled, according to NBC News. The prototype could take to the skies before the NTSB investigation is complete, the report added.
