Perhaps if the affected stone needs to be replaced (As suggested on Radio 4 this evening) the whole memorial should be moved to Air Cmd.
While from time to time I dislike the London Centric nature of our country the centre of the capital is the right place for this memorial.
I would suggest that one of the purposes of its location is so that future generations will look on it and it will cause them perhaps to pause and reflect on the valour and sacrifice of so many.
I think (at least I hope) that all those in Air Command both now and in the future will understand that the costs of the decisions they make may be counted in lives, sometimes tens of thousands of them.
