Heathrow Director (and others come to that) - thanks for your input. I started the thread so as to try and replace some of the cr@p that others start. I thought my topic was going to bring useful information forward, but all you lot want to do is slag me and the thread. I DO know what I'm talking about thank you but there are others on here who don't and want to learn more about how our environment ticks. It's a shame that all some people do with their time is run others down, not aimed at you LHR Director, rather than be proactive.
Think we can safely say that the thread is now CLOSED.
