BP remove leaking cap from Gulf oil well

Robotic submarines working a mile underwater removed a leaking cap from the gushing Gulf oil well, starting a painful trade-off in which more crude will flow into the sea for at least two days until a new seal can be mounted to capture all of it.

Officials said there was no guarantee for such a delicate operation almost a mile below the water’s surface and the permanent fix of plugging the well from the bottom remained set for mid-August.
