"This is the oil industry's Chernobyl."

Which raises the most ominous scenario for the industry: That there was no single, dramatic failure of technique or technology or human vigilance.
Although some media reports have focused on the rig's lack of an "acoustic trigger," another mechanism for remotely activating the blowout preventer, it seems unlikely to have made a difference. BP officials think the blowout preventer partially closed the pipe, because a full loss of well control would have created a leak 10 times greater in volume -- a gusher. Even with robotic submarines subsequently manipulating the control panel at the sea bottom, BP's technicians couldn't get the device to work properly.
Almost home free
An oddity of the disaster was the timing. What puzzles industry experts is that the most hazardous part of the operation, the initial drilling of the well, had been completed without incident. Deepwater Horizon was almost home free.
Whatever happened with the cement, the mud and the plugs, there was supposed to be a fail-safe mechanism: the blowout preventer. This massive apparatus has multiple valves that can close the well, plus a pair of blind-shear rams that can slice right through the pipe in an emergency.
Survivors say they hit the red button on the rig to activate the system. The device also has a "dead man's" switch that should have worked when the well erupted even if there was no manual signal from above.
