i adored stockton and p.h., who were on the trip with me. only stockton was in the submersible, not p.h. on that particular dive. but i didn t have any reservations. i just was so excited to be doing something that i d been hoping to do for 11 years. and what did stockton tell you at that time about safety? what did you ask him? did you know, for instance, that he had employed a sort of unorthodox construction of the submersible, that other people in the industry didn t know if it would work? basically, it wasn t industry standard. did you know that at the time? no, i did not know that. i did know, because i was originally supposed to go out in 2019 when they thought the pressure tests would be finished and titan would be able to take out passengers in 2019. and there was some sort of problems with weather in the bahamas where they were testing it and other things. and so they scratched all those trips that were scheduled for 2019. i think then the titan was
tested and found that maybe it had to be reinforced some more, which i think was done during 2020. i don t know all the details on that. and i was pretty confident, 2021 when i was on the trip, that it was safe. so david, what was the trip like? did you get a good view of the titanic ? okay, i that particular trip, i was on the fourth day of the five-day trip, we ended up near the stern rather than the bow. you re never sure what the currents are, and where we were released and started to do the two-hour descent, we ended up much closer to the stern. so i was very disappointed i didn t get to the bow, but the stern is still fascinating. it s a main geed, very big piece of metal. and we also were in the debris field. the next day, which was the last day for all those summer trips, three other men went down with stockton and p.h. and actually got to film the bow. and of course, when everyone thinks of the titanic, they
making the rounds in that community, a possible last transmission from p.h. nargeolet to the mother ship, the polar prince. the other thing that i heard was that p.h. had contacted the surface ship and said there was a problem. we re dropping weights and surfacing immediately. now, i can t verify that, but that to me meant something really happened very quickly. reporter: most of the ships participating in the massive search and rescue mission now returning to home port. some still on the scene, mapping the debris field, looking for clues in the shadow of the titanic, trying to understand with certainty what caused this latest tragedy in this isolated corner of the atlantic. so what they re doing now is mapping that debris field, trying to get a sense of the dynamic of that implosion and to drill down basically into what exactly happened. was it the carbon fiber hull? was it the titanium? was it the window? was it a combination of some or
come to meet with him. the u.s. coast guard will lead an investigation into exactly what went wrong, calling that titanic -bound submersible to implode and kill all five people on board. today grters will continue scouring the ocean floor for answer sthas they re mapping out a debris field about 1,600 feet from the titanic s residence. that should help to create a timeline of the incident. cnn s jason carroll explains. reporter: these are some of the first images of remotely operated vehicles which found portions of the titan s hull and continued on a new mission to search and map the debris site. the rovs will continue searching for more evidence of the accident. the submersible lost contact with the ship on the surface one hour and 45 minutes into its descent on sunday. the o thing i heard is p.h. had contacted the surfer ship
p.h. contacted them and said we re dropping and returning to the surface quickly. reporter: oceangate did not ask what gallo had heard. they look at the testing on f the materials used to make the hole. a cnn reviews while oceangate publicly touted a commitment to safety measures it rejected industry standards that would have posed greater scrutiny on its operations and vessels. special crew members safely diving to the ti titanic site. reporter: they touted an unforgettable and safe voyage. it also featured paul h. nargeolet, one of the passengers on board. it s very well done.
