In 2007, the cruise ship MV Explorer sank after hitting an iceberg off the Antarctic.
From my lower bunk I could not only hear the sound of ice banging and scraping against the hull of the ship, I could feel the vibrations of the impact through the wall and the cold radiating through the hull of the ship.
I was looking forward to setting foot on Antarctica, and wanted to make sure I was rested and ready to go the next day. I couldn’t let the banging of the ice keep me up all night…
Then there was a bang followed by what sounded like a creaky door in a haunted house swinging open and closed.
