Katrina Timeline: Unexecuted Plans

Just days before Hurricane Katrina hit, officials from state, local and federal agencies were hearing that this could very likely be the big one — the one they knew could devastate the city.

They spent the weekend in almost non-stop conference calls — making sure all the plans for food, water and security were in place. But even before the storm hit, some of the plans started to fall apart.

National Guard troops in other states sat ready, waiting for orders that never came. Instead, they were told to wait for an official plan and a chain of command to be established. NPR's Daniel Zwerdling and Laura Sullivan report.
