Titanic's Final Moments: Missing PiecesDramatic new revelations about the fate of the world's most famous ship. In 2005, an expedition to explore the wreckage made an interesting discovery south of the stern's debris field.

They said they found long strips of metal. Unfortunately, the submersible's camera equipment malfunctioned and they had no proof of what they saw.

But this set in motion a new theory. Maybe these long strips were from the bottom of the ship. If so, then Titanic just didn't graze the side of the iceberg, but it actually ran over part of the iceberg too.

We learn that an iceberg does not go straight down below the water (like a cliff); instead, the water causes the iceberg to form a shelf below the water.

Hence, it's now theorized that Titanic somewhat ran aground on the iceberg. If so, in addition to the gashes on the side, maybe there was also significant damage on the bottom, explaining how the ship sank in less than three hours.

If that were true, it could also explain why the front of the ship is relatively intact while the stern is crushed upon itself.
