The idiot "Nobel Prize Winner" Chu probably had to have his say.
The only possible logical explanation for how they changed the original BP plans, (Which were - New CAP, Near 100 % Collection, Wait on Relief Wells), is that they wanted to see how the well bore held up to increased pressure. That information could have been valuable to the operation of the Relief Well. But they were taking a big chance to get that info. So perhaps that means they are less confident about the Relief Well operation. At this point, a Top Kill is not a permanent solution. The Permanent solution is the Relief Well. They can try to flow mud and cement from the top again during the top kill, but that has already failed now twice.

No one ever got a Nobel Prize that wasn’t a dedicated communist.
