If you did not see 60 Minutes’ two segments on the Deepwater Horizon Blowout, then you should watch it now. Both segments are now available online.
According to this report there were several things that caused the disaster. The BOP had a hydraulic leak and a weak battery. Other than this there were three things that led to disaster.
1. The Annular, a rubber seal that is supposed to close off the well had been damaged. That problem was ignored.
2. One of the two control pods had lost some of its function. That problem was ignored.
3. Halliburton was to place three concrete plugs to seal the well. Traqnsocean wanted keep the mud in the column until all three plugs had been placed. But BP overruled them and ordered the mud pulled out before the third plug was in place. They ran a pressure test before pulling the mud but because the BOP was had a damaged gasket the results of the test was not accurate.
Anyway you must watch these two segments from 60 Minutes. It will make you mad as hell but I believe you will then know a whole lot more about what caused the blowout afterwards.

And, as if all this were not enough, the platform Atlantis may also be in danger of a catastrophic failure that would dwarf the Deepwater Horizon disaster.
