This story was re-told in my local paper and made me laugh:
Transcript of a radio conversation between the British and the Irish off the coast of Kerry in 1998:
Irish: Please divert your course 15 degrees to the south to avoid a collision.
British: Recommend you divert your course 15 degrees to the north to avoid a collision.
Irish: Negative. You will have to divert your course 15 degrees to the south to avoid a collision.
British: This is the captain of a British navy ship. I say again. Divert YOUR course.
Irish: Negative. I say again. You will have to divert YOUR course.
British: This is the aircraft carrier HMS Britannia, the second largest ship in the British Atlantic Fleet. We are accompanied by three destroyers, three cruisers and numerous support vessels. I demand you change your course 15 degrees to the north or countermeasures will be undertaken to ensure the safety of this ship.
Irish: We are a lighthouse. Your call!
