I 've spent a very large (too large) part of life on the M40, the A40, the M4 and the railways of NW London.
What I am saying is that military considerations are very very low on the political radar - especially when they are not a front line station.
If we started now, with the size of the RAF as it is how many airfields would we build to defend the UK? Germany manages with 11 - we probably have over 40. They are a relic of WW2 and TBH are not really necessary
