they are racing against time as new information suggests the batteries or the plane's pingers may already be dead. cnn's safety analyst david susi says a mechanical inspector told him the batteries may have been stored improperly. >> so the search is expected to begin tomorrow. but at this stage we don't know exactly when because it's still pretty rough weather we're getting reports from down in the search zone. it's important, too, to remember since this latest satellite image came out from thailand, there's been two days of nonflying because of the weather has been so bad there. so any of this debris could well have been scattered over quite a wide area given the strong winds and the high seas and also the normal currents there. so all that combines to make the job a really,raphy tough job even harder. >> every day they're not flying and searching is certainly a setback for them.
