do you just feel this urge to get out? well, i don t. but this is the kind of environment that if you don t like tight spaces, it would really give you a problem. also, even experienced divers like this, if you go down that deep a couple of miles down, phil, i mean, you can start thinking about the dangers you re encountering. and that in itself can be quite daunting. well, that s true. they don t feel any different. so if you were down at 20,000 feet inside a manned sub, you would feel exactly the way we do right now. the way we feel right now is sort of cramped right now. we are shoulder to shoulder. this craft is made to go down about a thousand feet. that s correct. for three people. we actually have four in here right now. ray, our photographer right here. i m going to turn around. we have jeff heaton in the back. he is our pilot. he is the one who guides the submersible around while we re up here in front, trying to do the robotic work with the
clausherphobia, it s great to have a look. what are the lights that are illuminating? we should point out it would be dog gone dark without them, right? we have an array of lights. 200 watts hmi lights and 300 watts hmi lights. these are the same lights that are used in hollywood to light up sets. they re very, very bright. we can t use too much light. otherwise, it illuminates the water just like turning your headlights on in the fog. reporter: right. you almost get too much light and then it bounces right back at you. that s right. reporter: the murkyness of the water, and we ve talked about this, phil. at that potential depth, they talked about silt, and that s a problem because any movement of this vessel is going to kick it up, and we ve seen that here. you see the way it hangs. once you kick it up, it hangs in a dust cloud, and you have to wait sometimes minutes, sometimes much longer for it to settle down and you have to be very careful and just inch your way along.
zarchlgts good morning. i m carol costello. thank you so much for joining me. today in the indian ocean the blue fin 21 finally completed its first full mission. nothing found yet, but if that unmanned submersible was unable to find any traces of the missing plane, an alternative could be a man vehicle. cnn s martin savidge joins me now from vancouver where he has dipped below the ocean s surface to show the challenges even these vehicles could face. good morning, martin. good morning, carol. i ll start off by telling you the vehicle that we are in, which is the aquarius is only designed to go to a depth of about maybe 1,000 feet. this is not the vehicle that would be tasked with retrieving things at the bottom of the indian ocean where 387 mh 370 is. it gives you a very good idea, though, of the conditions they re up against. phil newton is the man who is
