Over 100 days since the Deepwater Horizon met its fiery demise, setting off what has become the largest oil spill in U.S. history, things are finally looking up. The well has been sealed with a cap for more than two weeks. Final preparations are being made for a static kill of the well, which will fill the bore from the top with mud and cement and will be followed by a "bottom kill" of the well with mud and cement pumped in through the relief well. Even the globs of oil on the gulf's surface are beginning to dissipate. Yet there is still much to be done and a number of questions that remain to be answered.
