They can survive up to 40 days, you have to be right on top of the device to hear it. what we have here is our 90-day pinger which will be installed on new aircraft starting march of 2015. these have longer life and identical to the 30-day device, but give the searchers an additional 60 days of battery life to conclude the search and try to triangulate the location. >> mr. patel, two pingers. one in front of the plane and one in the rear of the plane? >> correct. each flight recorder and the voice recorder would have a pinger. >> and sko,o, i guess mr. hegg, once the submersibles go in, it wou...

Possibility of the pinger being located, then what they would normally do is basically try to develop from the surface ships, a 3-d map of the topography to get a real good understanding of what the terrain is. after that, they would be able to put down the underwater vehicles and be able to create missions based on whatever the underlying bottom topography would be in the area. >> anish patel and fred hegg, you added value. thank you so much. my next guest says despite headlines around the world, you are the safest you have ever been. i got this. [thinking] is it that time? the son picks up...

Narrowed it down now is very encouraging because the original 80,000 square mile area, when you talk that you're going to be able to survey maybe 10 to 30 square miles a day, we're talking in the area of seven years. now that they've got -- the more they can narrow down the search area and keep that environment quiet, not run any sonars for many additional ships, try to minimize the sea traffic in the area, as quiet as they can keep that area so that they can keep listening for these potential pings from the black boxes. that's what they really want to do to be able to narrow -- really narrow ...

Frequency was so low, there's a couple of things that could affect that. one, the main thing is temperature. at the bottom of the ocean, the temperature is very cold. and that can shift the frequency down a little bit. a few percent. but the other factor is the battery life. a lithium battery typically has a very flat response and as the battery dies, it's a very steep -- a very steep curve and so we -- it's possible that we could have been on that steep curve and heard the last gasps, so to speak, out of the black box pinger. but there still is hope for the next few days to try and relocate t...
