good evening from st. john s newfoundland. a lot has occurred. right behind me two ships involved in the search for the titan, the canadian coast guard vessel and another ship have just now returned here to port. this is them coming in just moments ago. the canadian coast guard ship anne harvey is expected here within the next hour or so and titan s support ship the polar prince is due back here overnight or early morning. polar prince left here as you know a week ago just today a week ago today traveling the more than 400 miles to the site of the at a tannic. it was to be titan s first trip of the season down to titanic. it blew apart and imploded. two different debris fields and they re hoping through pictures to understand and scanning that to understand exactly what the dynamic of that was and if they can learn anything from it. also just the number of warnings that we are now hearing about, about the sub. and i think we re going to hear more about the concerns rai
to them for all the reasons you talked about. repeated stress. being in the water. possibly becoming delam nated. the glue. it s the glue, the epoxy that holds it together. that gets into trouble and they are looking very hard at that in their own observation of it from afar. i m sure investigators will look at all of that as they put this together. tom foreman, appreciate it. thank you. up next, the former commander of the u.s. submarine fleet on the network of sensors that apparently detected the sound of titan imploding. plus, the sinking of a fishing troller in the mediterranean packed with migrants causes hundreds of lives to be lost.
