What Really Caused This?

This is still frightening even seven months later. More frightening still is trying to find out an openly disclosed cause for the incident. Go ahead, Google it and try to find out. It's so hard to find anything it's scary.

Go ahead- search the web and if you can find out the disclosed result without too much work.

There's no need to keep this so quiet. Litigation is one thing, but the rest of of us need to know what happened. It could help the rest of us stay safe.
