par, and one of them is about the viewing window within it, saying it s certified to go down to 13,000 meters, but then going down the titanic is 4,000 meters. that s well below where it s certified to. is that one of the areas that is causing you concern? not really. i mean, because they have taken this vessel down to this depth before. they have taken it down to relatively deep depths on previous excursions, i m not that worried about the viewing window. what i m more worried about in general, it seems to lack the basic safety features we would have incorporated into a submarine. for example, you can t open the hatch from the inside. if they were to get to the surface, they could run out of oxygen or suffocate because they can t open the hatch themselves, they have to get located and somebody has to open it for them. the communications are fairly minimal, yes, they use acoustic communications to talk to the surface ship. those can be interrupted by

and the search operation continues. and he was asked if any family members of those on board the vessel were on board the ship they launched from, they couldn t answer that question, which makes me wonder if there are family members in excruciating agony as they await word on their loved ones. let s talk about the noises. what specifically did they hear? do they have an idea of whether they heard specific noises that were manmade or noises that could potentially just be organic from the seabed or something banging against, i don t know, the metal ship wreck of the titanic itself? reporter: right, yeah, there s a lot of metal out there, and it s also, you know, the ocean is noisy. while we may not think about that. they were asked that specifically at the coast guard press conference today. tom costello asking could it have been some type of marine life. he asked from graphics institute who has been brought in as an
