Massive oil leak threatens Gulf coast

BP crews raced to protect the Gulf of Mexico coastline as a remote sub tried to shut off an underwater oil well gushing 42,000 gallons a day from the site of a wrecked drilling platform.

If crews cannot stop the leak quickly, they might have to drill another well to redirect the oil, a laborious process that could take about two months while oil washes up along a broad stretch of shore, from the white-sand beaches of Florida's Panhandle to the swamps of Louisiana.
