During WW2 many aircraft landed in the wrong country, some by accident some on purpose.
The history of 'navigational errors that led to allied aircraft ending up in in neutral countries is fairly well documented.
Ireland had a long history aircraft entering its airspace (Dublin bombed by accident) and landing either because of damage or navigational error. My and large allied crews were allowed home or to continue their journey whereas Axis crews spent the rest of the War in the Curragh.
