operation for the sub is being coordinated in boston. with urgency growing to rescue those onboard, there are now dozens of vessels scanning thousands of miles of ocean for any signs of the vessel. joining the search, a french vessel, the atalante. it has specialist equipment for searching the extreme depths and is nearly at the scene. we ll be looking in more detail at the technical challenges involved. our correspondent carl nasman is in boston. has there been at this point any updates on the search? many of those updates any updates on the search? many of those updates came any updates on the search? plan; of those updates came earlier today, this press conference by the us coast guard and he mentioned the key detail, those noises that have been picked up by canadian planes and these sonar buoys, they immediately redeployed some vehicles to the scene and began intensifying their search stop they have also said that they don t know what or who could have been making tho
have more details as well. let s take a look at what we know about the titan. the missing submersible weighs about 23,000 pounds or roughly 10,400 kilograms. the titan is about 22 feet long or 6.7 metres. it s also capable of reaching depths of up to 13,123 feet below sea level roughly 4,000 metres. and with the help of four electric thrusters, the titan reaches speeds of about three knots, or three miles per hour. we ve also learned today from the new york times that in 2018, submersible experts expressed concern to 0ceangate ceo stockton rush, who is on the titan. the authors of the letter expressed unanimous concern over the approach taken by 0ceangate when building the titan, and warned of potential catastrophic issues with its design. live now to our correspondent carl nasman, who is boston. you have been following the latest developments, has the coastguard giving any indications of signs of the location of the submersible? well, they are looking for this vess
Scene and began intensifying their search stop they have also said that they don t know what or who could have been making those noises, they don t have an exact location either, they have sent that audio data to us navy specialists and it is now being analysed to try to pick up any pattern or understand what was making that noise. it has injected even more urgency into the search. it is also getting much wider today, yesterday we heard it was about the size of connecticut and today it is twice the size of connecticut. it s very broad net being cast and you can imagine this being and you can imagine this being a lot like finding a needle in haystack, they looking utterly at the top of the haystack but all the way down below, 2.5 miles down under the surface of the ocean, there are some remote operated vehicles that are capable of reaching those depths and they are looking high and low for this missing vessel as time is running short. it vessel as time is running short. , ., , , ., shor
Very quick iteration cycle and that s part of the culture but when you re putting people down at 13,000 feet, the laws of mother nature will take over. so i think they might have gone a little too far and i admire the spirit but we know from years of submarines what it takes for all this discipline and the rego and the operational testing, but you have to do to maintain some brain safety. 50 have to do to maintain some brain safety- brain safety. so a question about maintaining - brain safety. so a question about maintaining safety l brain safety. so a question| about maintaining safety of brain safety. so a question - about maintaining safety of the submarine but we have heard reported it was controlled by a joystick, members were bolted in from outside, is that normal for this type of vessel? i don t think a joystick is normal, but again, i don t really have a huge problem with that. we would call it in the military commercial off the shelf technology. rather than the military going
