A week after Hurricane Katrina, dozens of military and U.S. Coast Guard helicopters filled the air over New Orleans, but it's getting harder to find people who needed rescuing.
One Navy helicopter crew flew in from Pensacola Naval Air Station, only to spend most of their 13-hour shift fruitlessly searching flooded neighborhoods.
The four-member Navy Seahawk 703 crew was beaten to one rescue by another helicopter, but late in the day they hoisted four men, two women and a dog from the stinking, oily brown water below.
Rescuers were searching house-to-house by land and boat looking for people still trapped by flood waters.
The Coast Guard is urging those who need help to hang brightly colored or white sheets, towels or anything else that might help draw attention.
