of that map up on the screen. we understand they're trying to get helicopters there, boats and ships as quickly as they can. there's concern that it could sink or be swept away? >> absolutely especially in shallow water as in thattia. if it is only 45 50 meters deep the current also move quite quickly. some of the currents combined with winds that are blowing through at that moment and the heating seas any debris could disappear quite quickly. i would expect them to get a helicopter out there before anything else. i don't think the distance offshore is too great. that would be what i would be using. >> so the process now, if they recover this debris they mark where it was found and then they work backwards looking at the currents and the tides and the wind conditions and that will
