This is based on an actual radio conversation between a U.S. Navy aircraft carrier (U.S.S. Abraham Lincoln) and Canadian authorities off the coast of Newfoundland in October, 1995. (The radio conversation was released by the Chief of Naval Operations on 10/10/95 authorized by the Freedom of Information Act.)
Canadians: Please divert your course 15 degrees to the South to avoid collision.
Americans: Recommend you divert your course 15 degrees to 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.
