UPDATE: (9:19 PM [CT]) Friday - There have been at least two and possibly as many as four times today that there has been something that looks like an explosion, and debris rains around, and for a while the ROV cameras go and look at something else (right now it is the riser outflow that we haven't seen for a while).
The riser outflow looks like shit, from this view some distance above. It seems fairly clear that yesterday's reports they've abandoned the top kill were correct, despite some continued junk shot efforts. The BOP may have been blown off and/or removed altogether, and the blowout(s) seems to have worsened in degree and is (are) now spewing what appears to be pure oil (no more mud).
Also, BP abandoned yesterday(!) the second relief well to direct those resources to try yet another high-risk procedure: placing another BOP on top of the (damaged, or entirely removed?) original BOP that had been(?) slowing the rate of flow, to some unknown degree.
In short, we don't know shit. But lots of people are volunteering hours of their time speculating, while BP's decision-making transparency remains practically non-existent.
Congratulations to BP for having reached 150 million gallons!
