passengers, the oxygen only lasts 15 minutes, whereas the crew has 45 minutes up to an hour and a half depending on where they were having an emergency. so they could have been cognizant. and let s move to the area of the next closer ping. and it will just expand exponential going forward? or do they need different assets? i hope that hms echo finishes the map and they have a good map. because that is something very important. with a good map you can decide which equipment you are going to use. because this is pretty flat or pretty good area, i would say the towing sonar could be better than bluefin, even if the bluefin has a sonar, too. but it will be probably more efficient, it can do it faster, a bigger area. there are pluses and minuses
between the towed when you are going to make a turn? in good weather it would be 60 to 70 hours. with the bluefin it takes five minutes, turning around, coming back. it stays down 24 hours at a time. exactly, and if you have a long track i will say the towing sonar is good. yeah. if you have a short track that is not good. because you spend a lot of time turning. and that would happen on the titanic, you know, first time we were using for the discovery, we were using a side scan sonar. and the turn, it was unbelievable. a lot of time, a lot of time you know because at this time the auv, like the bluefin, didn t exist. you have no choice. back in the olden days. hey, david, it is interesting, the families now have been so frustrated with the malaysian
and in this area, it was deeper. i mean, there are already some holes in their search. i mean, they cannot cover 100% with the bluefin. and the orion is a very competent tool. but without a map you don t know which one is the best equipment between the auv or the deep towing sonar. you know? because if it is very bumpy on the bottom you cannot choose a towing sonar. you will have a lot of gap area where the auv is better. but if it is pretty flat or if the towing sonar is very good, they should have a map first. we started with the map, and when we had the map we said okay, we can use this. we had the orion on board, another rov, we had the remus, all the equipment, just when we got to the map we said okay. with all the equipment we know which one we have to use. should they be releasing at least some of the pictures what they re seeing down there? it would be nice for the families to see. but sonar pictures of the bottom
i mean, they cannot cover 100% with the bluefin. and the orion is a very competent tool. but without a map you don t know which one is the best equipment between the auv or the deep towing sonar. you know? because if it is very bumpy on the bottom you cannot choose a towing sonar. you will have a lot of gap area where the auv is better. but if it is pretty flat or if the towing sonar is very good, they should have a map first. we started with the map, and when we had the map we said okay, we can use this. we had the orion on board, another rov, we had the remus, all the equipment, just when we got to the map we said okay. with all the equipment we know which one we have to use.
entirely gets into it like a very soft mattress almost. you kind of fall into it and go away. you have experienced the many depths, and what do you see? are you seeing what he is seeing? the silt, do you think it will be covered? no, i don t think so. because there are currents, you cannot avoid the visibility, that happened very often on the titanic, some days we don t have good visibility but some days we have a good one. it it could be that thing can change very fast. and speaking of the titanic, you used sonar technology to help to find the technology, right? tell us about that. we were using it was in 1985, we were using towing sonar, which was like the
