What if that second pipe did come up from below - does that mean that the capping of the well may not stop oil leaking out into surrounding layers down deep and then up into the sea bed? Could they successfully cap it, it stops leaking from the well head but leaks where nobody is looking? Then there are the predictions of an explosion occurring if the well is capped because it increases the pressure down below.
I like the idea of using the BPers as plugs btw.
Daddy, did you plug the hole yet?
