I had the privelege of a guided tour of the windtunnels there a while ago, what a fascinating place! I live locally, went to school within a couple of miles of the airfield and wind tunnels.
Unfortunately the airfield is now covered in parked cars. I flew over it many times during my training. Of course now part of the runway and some of the taxiways form the Palmer racing track. There were plans mooted recently to turn it back into an active airfield, but I think they've been shelved because of complaints from locals.
