Erm, the other south? Bit like when recieving a dubious "turn left here" instruction from SWMBO, I confirm with the "And which left is that, dear?" procedure from the Family Procedure Manual, Chapter 3.
Seriously though, I wonder which route they'd flight plan? AV to AD/ED is obvious & harmless enuf, but whichever way they return they will be zooming through their "cross ARBEY at" colleagues or being indulged with the sort of direct tracking through departing routes the keep-em-on-track Nazis seem to have won the war against elsewhere. Golly that was a long sentence.
