OceanGate said in a 2019 blog post that the certification process only assessed the vessels themselves - not operational safety, which it took seriously. He told the BBC he believed they hadn't done so because "they knew they wouldn't pass." National A former passenger details what it's like inside the missing Titan submersible "The only scenario that I could come up with in my mind that could account for that was an implosion, a shockwave event so powerful that it actually took out a secondary system that has its own pressure vessel and its own battery power supply, which is the transponder that the ship uses to track where the sub is," Cameron said. He said he immediately made some calls to his network and found out within about half an hour that the Titan had lost communications and tracking simultaneously. "Now there's one wreck lying next to the other wreck," he said, "for the same damn reason." Cameron was convinced the vessel had imploded on SundayĬameron told CNN that he was out on a ship himself on Sunday, so didn't hear about the missing vessel until Monday morning.
He said he regrets not speaking up more this time around. Navy heard the likely implosion of the missing Titan sub on SundayĬameron described OceanGate's use of a carbon-fiber hull as "fundamentally flawed" and said he had warned another company several years ago against using that same design principle. "And for a very similar tragedy, where warnings went unheeded, to take place at the same exact site, with all the diving that's going on all around the world, I think it's just astonishing, it's really quite surreal."Ĭameron stressed that deep submergence diving is "a mature art," with very few accidents when it began in the 1960s and an even better safety record now, thanks in large part to the certification protocols that almost all such vehicles follow - except this one.

"I'm struck by the similarity of the Titanic disaster itself, where the captain was repeatedly warned about ice ahead of his ship, and yet, he steamed up full speed into an ice field on a moonless night, and many people died as a result," Cameron said. Understanding Bohr's model requires some knowledge of electromagnetic radiation (or light).īohr's key idea in his model of the atom is that electrons occupy definite orbitals that require the electron to have a specific amount of energy.National Experts raised safety concerns about OceanGate years before its Titanic sub vanishedĬameron and many others in the deep submergence community had long been concerned about the vessel's safety and OceanGate's experimental approach, he said on Thursday, lamenting that the company had ignored experts' calls to undergo a standard certification process. In 1913, the Danish physicist Niels Bohr proposed a model of the electron cloud of an atom in which electrons orbit the nucleus and were able to produce atomic spectra. These difficulties cast a shadow on the planetary model and indicated that, eventually, it would have to be replaced. Furthermore, Rutherford's model was unable to describe how electrons give off light forming each element's unique atomic spectrum. If the electron circling the nucleus in an atom loses energy, it would necessarily have to move closer to the nucleus as it loses energy, and would eventually crash into the nucleus.

This is, after all, how we produce TV signals. It was already known that when a charged particle (such as an electron) moves in a curved path, it gives off some form of light and loses energy in doing so. Unfortunately, there was a serious flaw in the planetary model. \): Niels Bohr with Albert Einstein at Paul Ehrenfest's home in Leiden (December 1925).
