Nige,
The solution does not rest at Boscombe, a little further east methinks.
Whilst I am not wholly familiar with the problem identified, I understand it relates to systems critical to flying in IMC/poor WX conditions. Hardly, the sort of concern you need for a SF capability platform.
The flying carried out at Boscombe to keep the oil moving etc in the 'stored' aircraft has only taken place on nice clear days.
