A U.S. Coast Guard helicopter flies over the oil tanker Dubai Star in San Francisco Bay Friday, Oct. 30, 2009, seen from Oakland, California. The U.S. Coast Guard says the oil tanker has leaked fuel during a fuel transfer Friday morning into San Francisco Bay, creating a slick at least a mile long. Officials don’t know exactly how much oil has been spilled into the water about 2.5 miles (4 kilometers) southeast of the San Francisco-Oakland Bay Bridge. (AP Photo/Ben Margot)
