5. The Long Way Down
It took the Titanic around 15 minutes to reach the ocean floor. That means she sank at a rate of 10 miles per hour. Many passengers describe the sound of the ship sinking and that they heard when it hit the ocean floor. While videos have been available for years that explore the ship in its final resting place, the horror of hearing that ship hit the floor must have been devastating.
To make matters even more difficult to imagine, survivors were able to hear the ship imploding under the pressure of the water as it descended. Finally, (and not to ruin your day, but to put light into how tragic this was) air pockets allowed some passengers to stay on the ship as it flooded. This means that they journeyed to the ocean floor with the ship, experiencing the pressure until they found their final resting place as well. That is as graphic as it will get here.
