Not really you can still get inside with a ROV. They just need to make sure there is plenty of rope for the ROV so she can go deep into the wreak. Me personal I would like to see them go into the Engine room and have a look in there however, I don't know if this will be sealed or something! I would like them to explore the stern more as well. They always seems to explore the main front of the wreak however, I know becuase of the overhang of Titanic's stern it's quite dangerous and the possibility it may be hard to get inside because of the fact of how un recognizable the stern actualy is! I would like to see her cargo holds on the inside, her dinning rooms again and other areas of the wreak. They could get down into the engine room through the hatches in which the fireman used to get through on the smoke stacks! Am I right in thinking that?
