There is a little one liner in the report that gives the real reason. "The future basing of the Reds may have to be looked at".
So, after saving Scampton from the axe, shoving everything else in there to justify it's existence, the threat of DSA operations mean that the RAF will re-open Coltishall. The base will be the home of 10 aircraft and their maintainers. To justify keeping the base open, Neatishead will re-open and a new CRP will be built on the airfield at Colt.
It is anticipated that in 2009, the Reds will move to St Mawgan and then in 2012 to Lyneham.
On a serious note....I thought the BBMF were funded by charitable contributions not the taxpayer. As I understand it, the only Taxpayer assets are: The Dead Sparrows, The Royal Horse Artillery and HMS Victory.
