Dare I say, but occasionally a little more info from the radar guys and girls would go a long way on the day. Tower folk do realise that the radar folk are exceptionally busy, but when we are told very little to nothing with regards to what is going on, we will call now and again to find out what sort of delay can be expected. However, I agree that some of us probably call a little too often and don't give you any respite. Sounds like the DVD would be a good idea though.
PS We realise you guys are busy because we tend to visit Swanwick now and again. How many times do radar folk visit the towers?
