You do know that the Usumacinta disaster was a Pemex operation, don't you?
And did I know exclude Pemex from my statement?
Of course, I did. And I accept your apology...
I ain't apologizing for shit, pal. At the link I provided, click on the "rig list" link. You'll find dozens of rig disasters, thereby proving your statement "nothing like this has ever happened before" invalid.
