find it on a timely -- in a timely manner? >> well, first of all, aircraft are normally tracked through acars and other equipment, but if this equipment is tampered with, switched off or damaged or electrical power is lost to it, then, indeed, that tracking will fail. so you know, it's difficult to come up with something that is fail-proof, that allows aircraft to be tracked. >> right. >> but let me put this to you. there is an elt, the electronic locator transmitter, which sits in the roof of the aircraft, the 777, near the tail, and that's supposed to start transmitting signals to satellite when the aircraft is in water. however, it is not designed for high impact. so, if an aircraft was to hit water at very high speed, it could come off. so, that could be improved, and then the aircraft could be found. >> and those improvements are something that will be discussed in the days ahead. those black boxes are something they will be searching for in the days ahead, if this debris does turn out to be anything. because we are following the latest developments, this breaking news, debris spotted.
