I can't say I'm surprised by any of it. This is the sort of thing you see in every engineering industry, from software to chemical plants. Its always tempting

I can't say I'm surprised by any of it. This is the sort of thing you see in every engineering industry, from software to chemical plants. Its always tempting to skimp out on the additional safety measures, especially when one has skimped out them before without any consequence. I would be highly surprised if the Deepwater Horizon was the first rig to seal a well without the requisite number of centralizers.
