BP will attempt to shut down the oil well that's been spewing into the Gulf of Mexico later today. Step one: the "top-kill" method, illustrated here, wherein heavy drilling mud is forced deep into the well. Let's pray it works.
If the attempt is successful and the well is shut down, the whole thing will then be permanently sealed with concrete. If not - as in the case of the failed containment dome of two weeks ago - it's back to the drawing board. And on with the devastation. [NY Times]
