Flap 5, I think you might be a little disingenuous in your comparison to airline standby crews.
If you have enough standby crews in the right place at the right time to cover your entire summer programme, your airline is blowing a lot of money on people sat around doing nothing.
Anyway, I digress, the nice chaps on the other sectors simply gave the BRS and CWL traffic direct to the BRI/CDF and handed them over to the local radar units. It worked so well I might suggest it as a permanent feature! (Save your ire folks, I know it only worked cos' it was the middle of the night).
