now. not giving up. crews frantically searching for the missing submersible. they re desperately trying to rescue the five human beings before they run out of the oxygen. i will speak to a person who has been on the missing submersible before. and i ll speak with a man who says there is hope tonight. anti-vaxxers stalking and harassing one of the top vaccine experts after he criticized rfk engineer s crusade. let s got outfront. good evening. holding out hope. underwear noises detected in the search area for the missing titanic bound sub is raising the possibility they are still alive. time is running out. there could be hours left. the coast guard estimated this time last night, the sub had about 34 hours of beliefable air left. if there s still life support available on the submersible, and we will continue to hold out hope until the very end. the massive search, if successful would be the deepers underwater rescue is using buoys that they dropped into the water
96-hour limit, basically say that they will figure out, before they do anything else, they will figure out what happened to the titan. rescuers clinging to every sliver of hope. interesting sounds from the ocean depths could be a sign, the sign of life. the noises were heard by a canadian p-3. that was this morning and some yesterday. reporter: the noise described as banging sounds at regular intervals. in the homeland security briefing, they re described as less specific than that, but still the focus of the search. where he need to have hope, right? i can t tell you what the noises are. i think this is the most important point, we re searching where the noises are. the sounds picked up by buoys like this one, dropped from plane, then listening for any sign of life from the titan
like the titan, the pisces had limited area, just enough for 82 hours, the two men extended it by lying still, not talking. when they finally emerged after 84 hours, they only had enough for 12 minutes more. how different, the pisces was located quickly. the titan is still missing more than 400 miles from land. the pisces had steady communications. no one has spoken with the titan since it vanished. the titan is in much deeper water. even when the pisces was pulled up, the men inside was terribly battered. they thought they were going to be smashed unconscious. it was just spinning. reporter: there having under undersea rescue attempts. in 1999, when they save in less than 250 feet of water, 26 men

that s why they have started searching in that area. they haven t confirmed that those sounds were the titan, but they haven t confirmed that it wasn t the titan. they haven t ruled it out. now sent some robs in that area to try to fine tune whether or not those sounds are relevant. that s how you do a search pattern. and that s all they have right now. so they re looking there. mike, when we talk about the nearly 90 hours they ve been in there at this point, right, you went down and back up. it was a few hours. ten hours. so now it s 90 hours, close. were you trained on anything, on what to do if it lost communications. did you know if there was food, or did you know what to do if
