One of the concerns we've had here, I think, is that we've heard BP's executive vice-president for the U.S. saying that BP assumed that the blowout protectors there would work. My impression is that they're not really tested. I don't know if this is the first test of blowout protectors or not, in the gulf, but if so, they've failed miserably.
How can you give us some confidence that the blowout protectors that would be in place at the Orphan Basin, for example, would work?
