the bodies and of this ship. because it is 15,000 feet below the surface, it is possible to bring that up? >> it's going to be very, very difficult. obviously, if they need to to find out really to solve the mystery of what happened, they could possibly try to use this equipment that the navy has that can bring up submarines, but this is a huge ship, the el faro. it's probably not in one piece any way. so they might try, if they have to to bring up parts of it, but what they really want to get first, i think, would be the black box and if they do happen to -- my personal belief is they probably will find it very difficult to find bodies on board. >> one last quick question. sonar images appear to show whatever this is to be an upright position and in one piece based on what you just said. what does that alone tell you about what may have happened?
