Terrible news for Mildenhall, there's not much around there apart from farmland and trees. The local economy will take a big hit. Who has a need for a large military installation in the back end of nowhere ?
Alconbury is a different story, Huntingdon is desperately short of housing and the local economy is booming. The main airfield site at Alconbury is already being redeveloped having been handed back years ago.
Can't see much use for Molesworth unless someone wants some very secure storage. It could provide an alternative site for the firms that have been using Alconbury on a temporary basis for the last 20 years who have got to quit the site.
