Faulty Blow Out Preventer To Blame

Investigators: Leak caused well device to fail

These bozos could not even fix a leaky hydrolic line on the blow out preventer, not before the catastrophe and not now. What is wrong with these jerks? If they can't fix the problem, then they should be forced to step aside and let another group of people do the job. Are they evil or something?

A Peek at the Wellhead

Oil spill: Gulf of Mexico disaster 'growing by the moment'

This article has a nice graphic of the well head including an image taken of the robot submersible of the robot arm doing it's work. I see that there isn't a problem getting up to the well head and its BOP or Blow Out Preventer. So, is the problem electrical with the switches? Or is it a failure of an electronic or mechanical component? Is this something that can be repaired? If not, then why not?
