Allied aircraft were allowed to overfly County Donegal to bases in County Fermanagh. Many of these aircraft were manufactured in the United States, to be flown by the RAF. This was known as the Donegal Corridor. Navigational markings are still, faintly, visible on mountains, such as Slieve League. There were many unfortunate crashes into these mountains. The bodies of dead airmen were handed over at the border. At the border the Guard of Honour performed a drill with reversed arms, a Bugler sounded the Last Post and a Chaplain gave a Blessing. An Allied officer, embarrassed that the coffins' journeys were being continued in open lorries, thanked the Irish for the honour. The reply was: Ours is the honour, but yours is the glory.
