They proved the steel was weak a few years ago. They pulled a piece up, put it in a vice and hit it with a hammer, then watched as it shattered. It had a high carbon content, which means it didn't harden properly. And they recently found pictures that appeared to show fire damage along the hull on the side that was hit.
