you have all that sediment. so where the visibility was challenging when the ship was floating it's been reduced three times. instead of two feet of visibility, more like about four to six inches of visibility. and to try to locate something in that environment just incredibly difficult for these divers. >> they are literally probably feeling their way around. on electrify you were adamant there could be people in an air pocket and should get those cranes on that ship to stabilize it. couple of days later what are your thoughts? >> well, unfortunately, look i'm not on scene, so i can't understand why decisions were or were not made. with the resources of three kraens on scene i don't know why efforts were not made to keep the ship on the surface. hopefully we'll get more information about that. i got to be honest with you.
