Spare a thought for the unlucky Paddys that have to deal with the resultant flak every time there is a problem with the London computer. This is the third time in as many months that there has been an explosion of traffic through the Dublin and Shannon FIRs.
Mind you, its not just when the computers refuses to work at Swanwick that these problems occur. Its a daily occurance, every morning with the eastbound NAT London impose gallons of reroutes on the Irish so that they get what they want coming into English airspace.
In effect, Ireland has taken over the complexity of the airspace so that London don't have to deal with it. How much longer can NATS struggle on before the whole thing sits down?
