I just worry that right now is not the best time to do it; they are still working on maximizing the capture they get from their current cap. Unbloting the flanges, especially when it comes to unbloting the last 2, creates yet another entire set of ways the system can cave in on itself. They were just now starting make what even the msm had to admit was really progress, grasping at shadows of getting it all immediately like that does not seem prudent here, especially since they could completely lose the substance, in this case, having increased flow with none being captured.
They are not working on the BOP flange below the cap. This is something else.
