I find myself in agreement with Bismark here.
I totally agree it is important to preserve heritage and to ensure that where possible the MOD can support facilities and sites. But, Defence is under incredible financial pressures, and the demands for savings are incessant. That this measure is being looked at is a sign of how difficult times are.
Ultimately, Biggin Hill is no longer an active RAF site, and there must come a point when we have to ask why the RAF is paying to keep a chapel open when its not actually used by the RAF. The answer would either be to move it to another facility still in use (if there is no equivalent chapel at one of these sites), or to hand over to a charity to run on in perpetuity, like many other facilities have been.
I would far rather a charity ran this location and was able to keep it going properly, than the RAF pay a large sum of money for something its not using.
