from an ATC'r!
You had better believe it, 1127z the sh@t hit the fan, we got MDI of one every ten minutes then this was replaced with every flight having a slot - glasgow to edinburgh included! (work that one out) it is a nightmare when it happens though all credit to you lot, everyone this morning was really helpful - we are having a nightmare too (upto 10 replacement strips for each aircraft as the slots change etc) and it is nice when the pilots appreciate that - thanks!
