Does this support sabotage theory? "only one pipe in sections was used for drilling" and yet,"others have wondered if the mystery pipe isn't...a pipe that fell down the riser from the rig 5,000 feet above." Here is a bit more quoted from the article: "The idea that a loose pipe shot up from deeper in the well and prevented the shear ram from closing has been espoused by such experts as oil industry investment banker Matt Simmons and Bob Bea, a University of California at Berkeley engineer leading a scientific investigation into the blowout. But others have wondered if the mystery pipe isn't just a section of the same drill pipe that came loose, or even a pipe that fell down the riser from the rig 5,000 feet above.
The Coast Guard's acknowledgement of the two metal tubes Friday -- and a subsequent reference by BP to its plans to tie the two pipes together as the company installs a new oil collection system over the shaved-off riser -- actually comes more than a month after the Department of Energy noted the existence of two pipes using special imaging technology. At the time, BP dismissed the Energy findings as "impossible" because only one pipe in sections was used for drilling, a Tribune News Service story reported last month.
