This was one of about 5 documentaries that I watched recently, and it explains something that several people always question.

The berg traveled down from around where Greenland is, down iceberg alley and out into the Atlantic right into Titanic's path.

The interesting part was that it showed why it was so hard for the look out's to see the giant berg. Besides the fact that they lost their binoculars as the story goes.

Titanic was the only light source in the ocean that night. There was nothing else out there giving off light and allowing for any reflections. The water was calm, and part of what made everything so dangerous - again it was so calm the light wasn't bouncing off it. The look out's eyes were adjusted to the light on board ... imagine being in a lit room and looking out of a window into a giant field with no light, what do you see? Nothing...endless blackness.

If you had been sitting on the iceberg you would have seen Titanic coming, but as a person on the ship it was impossible to have seen the berg until it was to late.

Today there are high-powered spotlights and sonar that are useful in avoiding bergs.

As we all know had Titanic hit the berg straight on according to theory it would not have sank. The documentary also went on to prove that throwing the engines in reverse was very ineffective and worked against turning the ship hard a starboard.

All in all the documentary was very informational and I would recommend it to anyone.
