they should get nasa on this shit. i dont care what people say, nasa has some of the smartest people in the world working for them. even if they don't have the equipment/experience i'm sure they can figure this shit out. bp is pretty much trying the "...ehhh hopefully this will work" solution.
hmmmm....seems like they could cut the pipe off at the first leak, thread in new smaller pipe to where they cut the pipe, have a auto cut off installed on the new pipe, flick the shut off on very slow, flow is stopped!!!!
