and good evening from st. john s newfoundland. with a sad and somber evening here. this is where five explorers and would-be explorers were set off on friday, out into the open ocean, traveling so 460 miles from here towards the wreck of the artemis titanic. then, on sunday morning, they were sealed inside the submersible titan, and lowered into the ocean into their descend into the seabed some 13,000 feet below, about two miles. less than two hours later, communication as you know, was lost with the submersible. and we just learned it was about that time that a senior navy official tells cnn, that a navy network of underwater sensors picked up sound consistent they said, with an implosion. but it was determined to be quote, not definitive, unquote. and this afternoon, we learned the worst we this morning, an rov, a remote operated vehicle from the vessel horizon our tech, discovered the tail cone of the titan submersible, approximately 1600 feet from the battle of the tita
start doing carbon composite, or any kind of composite material. they re introducing to materials that are in contact with each other. the filament itself, and then the approximate tricks that it sits within. at that point, you have degradation failure. so, we always understood that this was the wrong material for submersibles. because with each pressure cycle, you can have progressive damage. so, it s quite insidious. you may have a number of successful dives, which is what happened here, and then have it fail later. if i were diving in a sub that was fully certified, i wouldn t think about it. even in my own sub, which had a steel hull, i knew that if i dove several two or three times, it was probably good to go, you could cycle steel hundreds of times. if not thousands of times. that s not the case with the composite.
