Last time I tried that was about 20 years ago, with no luck. There used to be a public right of way across the runway (!) which made for a few interesting approaches. When I mentioned this, and access to the church, I was told that the church had been de-consecrated in order to allow the right of way to be closed. They seem a little more helpful now.
On another note, there was a story went the rounds after the airfield closed that the runways and buildings had been mined during the war. It makes sense, since any invasion force would have got there pretty quickly and it would have given the Luftwaffe a base on British soil. The interesting bit about the rumour is that apparently this had been forgotten until the Station Commander's office was being stripped, when the switch panel was discovered. So all of us who worked there, including me, were literally sitting on bombs
