Hey Babjak,

when I saw the tile of your last post ( "Your call"  )  I was reminded of the following:

This is is the actual radio transcript of a conversation between a United States naval vessel with Canadian authorities off the coast of Newfoundland in October of 1995. This transcript was released by the Chief of Naval Operations on October 10, 1995.

CANADIANS: Please divert your course 15 degrees to the south to avoid a collision.

AMERICANS: Recommend you divert your course 15 degrees to the south 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, divert YOUR course!

AMERICANS: This is the aircraft carrier USS ABRAHAM LINCOLN, the second largest ship in the United States Atlantic Fleet. We are accompanied with 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.

Somewhat timely given the recent Canada-USA trade negotiations with the US having undertaken actions that will perhaps  do as much or more  damage  to themeselves , as to their number one trading partner
