Heady days indeed Talkdownman. I was one of the ATCA IIs on the A side at Preston. We of course did not have the "benefit"of the mediator but I seem to recall a couple of hours a week (was it Wednesday afternoons?) when LATCC reverted to manual whilst the confuser underwent routine maintenance. We always reckoned the estimates got better during that period. Incidentally I was one of the cadet material. Three happy vagrant years, followed by thirty five doing what for me was an ideal job.
