On Aug. 21, deep beneath the West Atlas oil rig in the Timor Sea off Australia's northwest coast, oil and gas began leaking from an as yet unidentified pipeline break. The rig was evacuated, and an oil slick began spreading into an environmentally sensitive area described as a "superhighway" for young turtles and whales. Plans were made to transport another drilling rig to help locate the leak and pump mud into it to stop the flow of oil.
