Because if we can hear it with the tpl you're only talking a couple of kilometers. so not that huge of a range. >> thank you. >> yeah, commander marks, this is david soucie, how are you? what i'd like to ask you -- >> doing well out here in the pacific. >> okay, great. what i'd like to ask you, when you saw that two-hour connection, when you were getting the pings for two hours, and i'm hearing they were not able to be re-acquired. i am hearing you went to the south. would you not go to the north? it appears because they were so far away from the two hours they may just be the refracted ping a...

Of putting the vehicles in the water, until they can be absolutely certain that there's no more life. >> all right. mike, to you now. how long do you think they'll continue with the tow pinger locator knowing the battery life is roughly 30 days and that it is almost over? >> sure. we've seen batteries last 35 and perhaps as long adds 38 days. i would expect they would continue on that track for a few more days until they hit one of the 35, 38 days and then likely not had a signal in 48 hours before they discontinue the tpl. that's the ur genergency. you don't want to switch over only to go dow...

Pingers from the black box of malaysian air flight 370. >> and one would think if there were black boxes out there the scientists would have told the authorities. >> absolutely, again, this is not a signal that occurs in nature. this is man made. and everything says this is malaysian air 370. >> david, time of course is of the essence because of the batteries. how much more time do think they will try to take to create these pings? >> we just heard from commander marks who said they would probably go two days without hearing pings before they would put in the bluefin. so if we go for one day i...

Sonobuoys, what does it tell us? >> one that the badries apparently are still alive which is very, very good news. they extended their regulatory shelf life, if you will. but also that the sonar buoys are helping. once the underwater submersibles go into the the water it will be weeks and not months. there have been other accidents where it's taken many months after the pingings were picked up to find it. here they want to limit that, narrow it down. >> narrowing it down, david, is exactly the whole goal of what they've been doing over the past few days since the past week since they've had th...

Pinger sound, or ricochet sound. the realtime, the scientists and technicians on the boat will be listening. >> pinger locaters have been used for years. in 1996, a tpl successfully located the black box for twa flight 100, in 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 will deploy this autonomous under water vehicle that maps the ocean floor. >> it will start to run patterns back and forth, shooting sound out the side and taking pictures....
