The VGS went in August last year, drops have not been carried out for a very long time and the MQ sites do not impinge on the airfield.
However although 90 acres were advertised on the open market late last year, the 536 acres that Dyson has bought do not appear to have been openly marketed.Given the potentially huge financial benefit to the local economy plus the 3000 jobs created, maybe it is the right decision just to to do a deal with Dyson.Far better than hundreds of tacky houses I think.
621 are storing some kit at Little Rissington, local rumour is that South Cerney is the new base but how that would work with Fairford departures remains to be seen.
