Opportunity for the Taking
Pr00ne,
The lack of (i.e. zero) building activity on the airfield to date perhaps shows best the negative appetite to build anything there, probably because of the poor service infrastructure and road links, and probably because Braintree District Council has other plans for new housing (for example).
It will be for someone to decide whether this unexpected new opportunity (a 'ready made' and previously proven VGS site) should be put back to its former and recent use (since the 1980s). I accept that it will take a small amount of enthusiasm, but not that much effort.
The reality is that 614 VGS would never have been moved out of Wethersfield in the first place (given its proximity to large numbers of ATC squadrons) had the extension to 2025 been known about upfront, and gliding would have already recommenced there by now.
