Survivors in Japan fending for themselves

SHIZUGAWA, Japan - Above the din of the rotor, an American helicopter crewman shouted, "What do these people need? Do they need food? Do they need medicine?"

The answer one week after a tsunami devastated Japan's northeast coast is they need everything.

Aid has started trickling in, but much of it appears ad hoc and many survivors remain isolated and cold and are fending for themselves.
