I think it is a good idea to show clips like these. I have been asking for a long time now for permission to use clips like that on here to show people what actually happens.
I have seen three real eye-openers in the past on a visit to LATCC and had a controller sitting with us explaining what was going on. It was really eye opening as I said when you see things like that and know what the brilliant controllers have to do when it happens.
I have also seen one happen for real when visiting LATCC with a few people from here. We watched silently as the aeroplane went into the Luton zone heading straight for the approach to 08. The controller was great, he was calm, he had to divert a few heavies and he still had time to explain to us what was going on as he was doing it, why he had to divert and what was going to happen next, he was always one step ahead.
I just wish some one at NATS would let me host those files/clips on here for everyone to see. They should be distributed to all flying schools and clubs to enable as many pilots as possible to see these things.
