The MOD later decided that DARA's 'Fast Jets' and 'Engines' businesses would close by April 2007, although the 'Large Aircraft' business would continue and, on 14 April 2005, the Project Red Dragon super-hangar opened and DARA moved its VC10 operations from its existing 'Twin Peaks' hangar into the new facility. A 2009 report from the National Audit Office concluded that "The MOD and the Welsh Authorities did not work sufficiently closely during the project. Although they had complementary objectives, there was no common purpose between them, with the MOD interested in securing more efficient repair of fast jets and the Welsh Authorities interested in safeguarding and creating jobs in South Wales. The MOD and the Welsh Authorities did not have a shared understanding of each other’s key assumptions. The Red Dragon project highlights the danger in large and complex projects that involve multiple public bodies of insufficient openness and information sharing."
