State and local officials were left wondering what exactly went wrong in the wake of a 58,000 gallon oil spill in San Francisco Bay - the largest such spill since 1988 - this past Wednesday. The Cosco Busan, a South Korea-bound container ship, struck one of the Bay Bridge's steel and concrete buttresses Wednesday morning as it was being guided out; the impact gouged the hull, precipitating the massive spill.
