Icerberg that sunk Titanic.

When you look at it, it's hard to believe this hunk of ice was behind the tragedy of the Titanic. This photo of the iceberg as well as 2 others in existence was snapped by a passenger on the Carpathia, the ship that answered the Titanic's SOS call. As far as I have been able to tell, this was the first because the scrap of Titanic hull paint is the largest. The berg stood about 100 feet over the water and even threw some chunks onto Titanic's deck as it passed, which some passengers played soccer with, believing they were safe. It's now thought that substandard steel used in making the Titanic's rivets was so brittle that pressure caused them to snap, making the plates push apart. The berg, which was seen to melt away and change while in visual range, it drifted off during the recovery of victims' bodies and unlike the Titanic, was never to be seen again.
