Maybe their Airships have forgotten. In the not too distant past, during a meeting of the Air Force Board Standing Committee, the then CAS said that the biggest mistake they had ever made was in closing Chiv instead of Valley. Valley was such an unpopular choice of posting that it was agreed that if another base had to be closed then it should be Valley. Maybe they should look up the Minutes of the old AFBSC meetings?
Also, now that tree huggers carry such weight and political correctness is the order of the day, we have to clean up our bases before we can walk away and sell the land at giveaway prices to real estate developers. The last I heard, the cost of clearing up more than exceeded the revenue we/the Treasury would make from any sale. Mind you, if it was the Armed Forces budget that paid for the clear up and the Treasury who got the money from the sale.........
And I can't even spell Sinisism!
