It was the last line of defense, the final barrier between the rushing volcanic fury of oil and gas and one of the worst environmental disasters in United States history.Its very name the blind shear ram suggested its blunt purpose. When all else failed, if the crew of the Deepwater Horizon oil rig lost control of a well, if a dreaded blowout came, the blind shear rams two tough blades were poised to slice through the drill pipe, seal the well and save the day. Everything else could go wrong, just so long as the pinchers went right. All it took was one mighty stroke. On the night of April 20, minutes after an enormous blowout ripped through the Deepwater Horizon, the rigs desperate crew pinned all hope on this last line of defense. But the line did not hold.
