The most critical time in the oil spill crisis in the Gulf of Mexico is at hand, as BP engineers armed with 50,000 barrels of dense mud and a fleet of robotic submarines are poised to attempt what they call a "top kill" maneuver to plug the gushing well a mile below the surface.
BP chief executive Tony Hayward said Wednesday morning that the company hadn't yet decided whether to go forward with the risky plan, which rather than sealing the well could possibly make the leak worse. “Over the last 12 hours, continuing through the night, we have continued to take pressure readings and establish flow pulse,” Hayward said on NBC's "Today" show. "I will review that with the team and I will take a final decision as to whether or not we should proceed."
BP officials said that the top kill maneuver “has been done successfully in the past, but it hasn't been done at this depth.”
