Just an interesting theory I heard today from some internet article. Some are now claiming that the explosion actually sent a damaging shock wave to the sea bed. Enough that those running the show are worried that capping the well straight out would allow pressure to build back up and actually blow out the weakened sea floor and cause a major oil geyser to explode out of a sea floor crack. Thus causing an un-repairable and catastrophic like event. That is why everything seems to being done in small incremental steps.

Not sure how much reality there is to it but crazy thought.

Just seems so hard to believe we can put little dune buggy's on Mars but can’t stop a leak a mile under the ocean. Space the final frontier my ass...
