This is the transcript of the actual radio conversation of a US naval ship with Canadian authorities off the Newfoundland coast in October 1995. Radio conversation released by the Chief of Naval Operations 10-10-95.
Canadians: Please divert your course 15 degrees the South to avoid collision.
Americans: Recommend you divert your course 15 degrees the North to avoid a collision.
Canadians: Negative. You will have to divert your course 15 degrees to the South to avoid a collision.
Americans: This is the captain of a US Navy ship. I say again, divert your course.
Canadians: No. I say again, you divert YOUR course.
Americans: This is the aircraft carrier USS Lincoln, the second largest ship in the United States' Atlantic Fleet. We are accompanied by three destroyers, three cruisers and numerous support vessels. I demand that you change your course 15 degrees north. I say again, that's one five degrees north or counter-measures will be undertaken to ensure the safety of this ship.
Canadians: This is a lighthouse. Your call.
