as a catastrophic implosion, about timing. you remember, when the titan began its descent early sunday morning, it was about one hour and 45 minutes into its descent when all of a sudden it lost contact with the surface ship. so i asked him, do they believe this, quote, unquote, catastrophic implosion happened at that moment? he couldn t give a definitive answer. there needs to be more investigation into that, but what i can tell you is, he also said that they had been they had dropped sonar buoys all throughout that particular area and the sonar buoys, he said did not pick up any sounds that would indicate some type of catastrophic implosion, at least at that time. that seems to suggest, again, i caution, the investigation now under way, but that seems to suggest that this catastrophic
and then metallic sounds. this was under the underwater telephone. somebody on thresher thought it might be useful to notify the surface ship that they were having trouble. so i am very intrigued, and there must be some record what the last communication was between the mother ship and titan. sandra: coming off yesterday when there was a glimmer of hope when the sounds were reported and that was thought to maybe, and by some chance be the crew on board trying to alert where they were. now reports of this debris field. if in the case, brad, they are not able to determine that that debris is from titan, do you believe they are going to continue this search based on the timeline of the oxygen running out, that the coast guard initially worked off of? that s probably one of the most painful questions for somebody, thankfully not for me, to make that determination. when do you decide to reclassify
losing power, power going off? certainly they lost the power that enabled them to communicate with the surface ship that was supporting them. and the communication systems went down, there are two primary ones, navigation system, because officially there is no gps once you get into the water. the radio signals from satellites don t penetrate the water, so what you haveis penetrate the water, so what you have is an acoustic system the shipping is the sub, so the ship has got gps so it knows where it is and it knows where the sub is relative to its commander so it can direct the sub and so you need to go right because the titanic wreck is over there. but then they also have a short messaging system, bit like a text message on a mobile phone, and they communicate between the sub and they communicate between the sub and the surface support vessel through that. both of those systems seem to have gone down. and that s why they haven t been able to contact. truth? haven t been able to contact
but they must have reasons to expand the search area to look there. i think you have to continue the air search in case the sub is at the surface. but i think it s so you can t ignore the banging. and you don t have time to wait to analyze the sounds exactly. so you have to assume, i think, that they are human made and then move equipment in that direction right now so that if the analysis happens and you say, okay, that s the sub that you are already have vehiclesen t on the spot. there is no time to waste with waiting to analyze before you move that way. and i am sure the coast guard is doing that. they are moving in fact, i heard that. they are vectoring in on that area. so my hope is that they do that quickly. i don t know if they ve responded to the banging or sounds with another sound from the surface ship, from a surface
has been deployed to that search site. rovs are about the size of a cargo van and they are tethered to a surface ship with a 2 inch thick cable which provides power and communication. now, u.s. military rovs have electric motors and cameras but would not have the capacity to actually be able to lift that submersible. that is where this piece of technology could come in. experts have suggested an rov could attach a cable to what s called the fly away deep ocean salvage system. it has the ability to lift loads up to 60,000 pounds and could potentially haul the submersible to the surface, but, of course, they have to find it first and that is where the trick it, kate. absolutely. the u.s. coast guard, u.s. navy, canadian coast guard they have been on this search and rescue mission since sunday. now the u.s. military is offering up additional assets to assist in what is clearly becoming a massive effort.
