The top kill has been declared to have failed. Bugger.
I think we're up to plan H now (notably similar to preparation H) which is a sea floor riser containment thing. I don't know how that differs from the top hat thing was tried earlier.
The relief well is the only reliable solution. That is still a long way off. I kind of wonder if all the other attempts are expected to fail but are being done to maintain the appearance of doing something.
