zero visibility. large piece of wreckage initially believed to be part of the missing plane. it turned out to be part of a sunken ship. >> search teams, however, managed to find three more bodies today, bringing the total number of victims recovered to 37. each victim is returned to surabaya, need indonesia, where the doomed flight originated. >> the visibility has been so bad over the last 24 hours divers say they can't see right in front of them once they surface, the waves are just brutal. we saw some of that before. chad myers joins us from the cnn weathercenter in atlanta and also joining us are aviation analyst miles o'brien. chad let me start with you. chad it's very very difficult there on the bottom of the sea. >> it's like trying to drive on the highway in dense fog with your high beams on. you can't see anything. the divers will have bright spotlight bus all of the particle, all that muck, the murk in the water will be reflected back at the diver's face and so think about trying to go down somewhere where you know there will be danger.
