Donegal Corridor
The Donegal Corridor (Irish: Muinchinn Dúin na nGall) was a narrow strip of Irish airspace linking RAF Castle Archdale on Lough Erne to the international waters of the Atlantic Ocean through which the Irish Government permitted flights by British military aircraft during World War II. This was a contravention of Irish neutrality and was not publicised at the time. == Background == When the Second World War broke out in September 1939, Ireland remained neutral, in accordance with its pre-declared neutrality policy.
