In December 2007, Defence Secretary Des Browne agreed to conduct a fresh report into the crash. On 8 December 2008, Secretary of State for Defence John Hutton announced that "no new evidence" had been presented and the verdicts of gross negligence against the flight crew would stand. On 4 January 2010, doubts of the official explanation were raised again with the discovery that an internal MOD document, which had been written nine months prior to the incident, described the engine software as 'positively dangerous' as it could lead to failure of both engines. The 2011 Review concluded that criticism that the original board had not paid enough attention to maintenance and technical issues was unjustified.
