John,
Being interested in the more historical aspects of the Air Corps,the position of the internees was that all Germans were interned because if they landed in Ireland they HAD to be on an operational mission. The position for the British was different and here again Mac Carron gets it wrong, there are many cases when RAF personnel were interned even though they were on training flights e.g. the Fairey Battle at Waterford the Polish pilot was interned, the Miles Master in Co. Louth, the Blenheim at Clontarf and so on(slightly different it was an unauthorised flight). The position of F/Lt West was that he was running a conversion course on the Miles Master and Hurricane just like they did in Turkey or Portugal, neutrals who operated some British types. The Irish Government was anxious to release all the internees after a certain period but the British were opposed to this for some time as they were anxious that no U boat personnel(who were in short supply) were released, but as it happened there were none interned until March 1945. They Irish had to feed and guard the internees at a cost. How I wonder could the Germans have got to Germany of France. The Irish Government continued to adopt a pragmatic approach, there was little else that we could do.
Best regards,
