apaddyinuk - Thanks. It is not often on these pages someone is in agreement with me. I do feel very strongly that as a nation of excellent engineers we have been sacrificed time and again on the high alter of politics. What a short sighted, lilly livered bunch of hypocrits our politicians appear to have been over the ages. Just think about Concorde, TSR2, Hovercraft, Harrier, to name but a few! Sorry to everyone for being somewhat off topic, rant over.
