They’ve tried underwater robots, a containment dome, a riser tube (which has been siphoning up at least a bit of the gushing flow), and relief wells (still being drilled, a process that will take months). They’re now attempting a top kill. They might still try a junk shot and top hat, and — what the hell — even nukes. [UPDATE, 30 May 2010: Top kill tanked. Next up: lower marine riser package (LMRP) cap.]
So far, total fail.
