In the Gulf of Mexico on Tuesday, oil continues to pour from a well a mile under water. Calmer weather has officials optimistic they may be gaining ground in dispersing the crude before it reaches the shore. Crews plan to drop dispersants from a plane to break up oil on the water. They're also using an underwater vehicle to pump chemicals into the oil plume, breaking it up before it rises. Along the Gulf shore, volunteers are being trained to clean animals tainted with oil if and when they start arriving. In Biloxi, Miss., residents are waiting for whatever is coming next.
