Did Ops in DUB start sending some sort of ACARS messages to continue (if they can)?
I can assure they don't - ACARS - we wish!!
Good grief, never seen such a fuss over nothing - you know these a/c will fly on one engine - you also need time to prepare, brief the cabin, even burn a bit of the weight off prior to landing. Sounds like good decison making to me - Captains are paid to make such decisions and it says "Nearest" (which means in terms of time not distance) "Suitable" airport - GRO seems a lot more suitable to me than BZR.
