Well, I think it is pretty clear they know HOW it happened. Sadly, so far, the containment efforts have failed.

BP has about 5,000 such wells around the world. 1 failure out of 5,000 is a pretty good ratio.


As for telling my daughter about this, should she ask some day... "Honey, 'doo doo occurs'. Through out history, man has strived to make their lives better. Cheap and abundant energy is reason number one we live the lifestyle we do. Sadly, sometimes things like this happen. That's life. When bad things happen, learn from it, fix it if possible and keep going."
