As a serving officer I'm surprised by some of these posts. Personally I've found the club useful and helpful and have stayed there on many occasions. Once at very short notice, late at night after a concert in Hyde Park.... Although I did receive some strange looks.
A quick email the day before along the lines of '...I know it's a long shot but what are the chances...' has yielded the goods more than once.
In my view the key to success is to not be put off easily and have a bit off old fashioned tenacity as it's often worth it.
Finally and contrary to the more cynical, of course the ratio of serving to non serving is going to be disproportionate, the place would be unsustainable otherwise.
My one criticism is that I have yet to see a painting of a any form of rotary asset in there!!! I know it is (sorry was) a fast jet RAF but lets sort that one out.
