Think they should stop mucking around and either:
A) turn it into a proper commercial use airport which the airlines can then use - i.e. realign the runway with Heathrow's and in the process lengthen it for regional jet compatibility, consequentially forget the third runway at Heathrow, get in the regional operators to improve national connectivity with London, link new passenger terminal with Hillingdon tube station - job done.
or
B) close it entirely and develop the site for desperately needed housing (and build the third runway at Heathrow)
Living with the status quo is simply daft with a mere handful of military movements a week, if that, whilst all the other valuable slots are only available to private aviation - no benefit at all to the general public, nor of any benefit to London and 'UK PLC' in general.
Why didn't the Davies Commission dwell a little more on option (A) above? Politics and self interest on the part of the MOD? Far less costly than a third LHR runway, even if you added a 6 mile underground tube link to Heathrow for connectivity.
As it remains, it has dubious compliance with civil aerodrome standards whilst being used by 95% private aviation. Only time before something clips one of the hundreds of unlit obstacles in the way, or comes off the end of the runway because they think they can go in much heavier than they should actually be.
