Shallow waters off new york. investigators used one in 2009 when air france flight 447 went down in the atlantic but found nothing. if they have any luck locating the pinger from flight 370, next they ll deploy this autonomous underwater vehicle. it maps the ocean floor. it will start running patterns back and forth, shooting sound out the side and taking pictures. it will show objects, shiny objects basically, bright objects that could be the plane. reporter: right now, that s the perfect scenario. but even the head of the search effort seems to be hedging his bets. hopefully, hopefully, the calculations putting us into about the right area. reporter: randi kaye, cnn, new york. our thanks to randi. joining me to talk again is analyst david gallo, also with us sylvan pascoe who was a technical adviser in the investigation of the air france 447 crash. and sylvan, let me start with ....
Up until this point we ve been told that it will probably just be used once they found debris, once they had a greater sense of an area to search. interesting that you suggest that maybe they need to start using it right now. sylvan, that make sense to you? absolutely. i mean, you can put everything you have under water because time is running out. so i would do exactly the same thing. you also, sylvan, say that you think that this is all right now obviously based on data, the analysis of the data. right now there s just a big math problem being solved by smart people in a room. do you think there s more data out there and do you think there needs to be a better analysis? that s a very good question. because in the case of air france, on one hand we had too much data. on the other hand we had too little data. the idea was to backtrack the data that could help us on the ocean as opposed to the air problem. so we sort of went through the data and then found new data ....
Traditional way of thinking you d wait until you heard picked up the pinger locater, then deploy that. but i m thinking if we have faith in that area, as big as it is, it can t really hurt anything to get that vehicle in the water, get some operational expertise in that area, see what you see, and start crossing areas off where the plane isn t. and i think that s important information now. so i think it can be valuable. but you don t want to burn out the teams, either. they want to be pretty judicious. the one thing i have to say is that once this gets going full speed, both vehicles in the water, we need to leave that team alone. because they re going to be plenty busy and they can t second guess what they re doing. they need to do their jobs without interference. interesting what you say about the blue fin. up until this point we ve been told that it will probably just be used once they found debris, once they had a greater sense of an area to search. interesting that you suggest ....

it took a long time to analyze the data. and the good information, the not so good information. because you don t want to burn out crews and stuff searching around needlessly. you want to get all your ducks in the row. exactly. in this case it s just where do you begin? without that last known position, without any shred of evidence that the plane s in the water at all, where in the world do you but things like that, things like bureaucracy, getting permissions, all of that impacts an investigation. sure. in retrospect looking back. and this is only multiplied given the number of countries involved, the number of foreign nationals involved. totally understandable. we were talking earlier today about how unfortunate it is that we find ourself back in this situation just a few years after air france there. needs to be a better system to deal with these things with a rapid response where people cooperate. and here we have the same kinds of issues about who s doing what and ....
