It was not just one way traffic from North Ireland. We were due for an afternoon navex from 2 ANS, route the usual triangle Thorney - Point of Ayre - Alnwick - TI. However we were told that we were to take a passenger to Aldergrove. Whoever he was or why I know not but it only cost R.A.F. about an extra 80 (statute) route miles.
It was only the time I've been to Ulster and all I saw was a solitary hare on a damp airfield.
P.S. Obviously we used Aldergrove not Point of Ayre as our turning point.
