I think people should remember a couple of recent successes. North Weald has been at risk for years but has survived even though it's no where near as busy as WAP. Kemble has also won a major battle against NIMBYs.
I spent a lot of happy hours at WAC during advanced training and then spent some time instructing there. It's very busy and a viable business. I would be very surprised if it is at risk.
The vast majority of pilots there are very good at complying with noise abatement routes, even if these do take you outside the ATZ when using rwy24. I'm sure that the regular complainers would be absolutely genocidal if they had to contend with the masses of the great unwashed if a football stadium were to be built there.
It's a great airfield with some wonderful people working there. Long live WAP!
