Underwater oil plume estimated to be 10 miles long, 3 miles wide.   Oil over one of five major deep coral reefs.  Dead porpoises wash up on shore. 
 
BP proud that they've inserted a 4-inch draft into a 20-inch pipe, collecting about a fifth of what is continuing to spill daily.

    bad math riot. you can fit five 4" pipes down just one axis of a 20" pipe. that's assuming 20" is the interior dimension of the larger pipe and 4" the exterior dimension of the smaller. which isn't the case. but pretending it is, you still have a lot of 20" pipe left after you do that.
 
   4" pipe area is the radius (2') x 3.14 squared= 39.4 square inches
 
   20" pipe area is the radius (10") x 3.14 squared = 986 square inches
 
   that's about 4%, not 20%.
