hear, we think from a company called horizon maritime services which effectively run the mothership that the sub was in contact with. we believe this will be the first time we have heard from them. we are waiting for that press conference any moment now. my colleague carl is sitting by for us butjust before we go to him, i want to show you where he is and also where the search is. we can take a look at the map now. this will give you some idea of the geography of where the rescue effort is being coordinated, where the wreckage of the titanic is, as he could see there in where the sub was heading down towards. and of course the search area which is a huge and expanding area is now. in the last 90 minutes we did get an update on some of the things that are directing and pushing for this search effort. this is about noises, banging noises. for more excavation on what exactly that means can cross now to carl in boston. good to see you at talk us through what we learned about thes
