at the end of the front were only 100 -- i have the list here, only 194 objects from the entire 737 which broke up. this was in an area where people were actively looking for it in the islands of indonesia. i guess i'm not surprised we don't have debris. in this case there was head rests, tray, one piece of the tail and one piece of aluminum and that's it. not finding debris doesn't assume it is all together but it is a vast ocean and even on this plane there wasn't much left floating. >> it's amazing. we keep thinking why hasn't anything -- but the ocean is a very big place. this is from robert and he says will the atmospheric pressure damage the black boxes? >> no. they are specifically designed to function perfectly well down to 6,000 meters. at the moment we are at 4 1/2
