Interestingly, Matt Simmons was saying today (with agreement from others) that there’s no way this hole in this pipe created the surface slick that is now about as big as Maryland and Delaware. There was another plume, several miles away, and he believes that the bulk of the oil is flowing from another broken pipe along the floor of the ocean.
Here is a picture to help out. Directly under the drillship is the end of the riser where the majority of the leak was occurring. This is where they had the insertion tube plugged in. (This has been removed for now while they work on the top kill.) The leaks we are watching right now are at the top of the BOP stack. These are two different locations on the same pipe.
