>> mary schiavo, youve been involved investigating stuff like this. do you see this as potentially the key lead? >> i see it as one of two key leads. i was most intrigued today about the final additional partial ping. i know that doesnt sound like much. but that is also a source of information where when the sonar scanners and submersibles and equipment to find the pingers finally arrive that is where you would want to send them. the black boxes and heavier parts of the plane would not have floa...

Interestingly enough, when the auxiliary power unit senses theres no power to the plane, at all, it actually restarts. the auxiliary power unit has its own fuel source, a separate fuel source. it starts up. so power would actually return to the plane for the last few minutes of that descent and that may possibly explain that partial ping they pick ed up where the power returns to the plane. >> you answered the question, as i said to richard as you were saying it, would that explain that partial ...

Australians. so every day is different. it just depends on where they need us. thats an australian-coordinated assignment that we get via the ato. >> everybody sort of divides up the territory to make sure youre not overlapping, is that right? >> yeah, thats correct. and you know, one thing to stress is this is still a big area, and were talking hundreds of miles. and to be quite honest, still too big to effectively get a good sense of where the plane may have crash landed. and as you know, we r...

Its an extremely daunting task to find them. >> i also in london lived by the river thames for a few years. the amount of stuff that used to just wash past every day. thats not a big busy ocean. it was quite a calm river. that also must be a possibility. this could be anything drifting around. >> it could be anything. and there are trash piles out there in every ocean since plastic was really introduced theres these giant 900-fold increase in trash out there. so this could be a trash pile. in th...

To listen to this underwater acoustic pinger. we need to establish this location before this time runs out. >> i suppose that is fine fine, matt with the satellites we know where we think the debris field is go 500 miles looking at the drifts current. go 500 miles back in every sort of direction and put those two devices the one that goes underwater and the one in the service to locate the ping. we are running out of time. >> yeah, this would be the one under the surface. you need to keep in min...

Without the pinger. it took two years to find it from flight 447 after it crashed off the coast of brazil in 2009. search teams towed pingers near the debris field days after the crash and heard nothing, suggesting that pingers had stopped working or the signal was somehow blocked by rugged underwater terrain or other obstacles. >> even plant life, seaweed, coral, any of those things can detract from the signal and even temperature changes in the water. if you have a thermal layer, it can hide t...

Going to happen where what really caused their plan to go wrong, whatever their plan maybe. these would be confederates living on land conducting their lives also waiting to go see what happens. so once this thing is resolved, there could be another attempt that whatever this was driving it. but ill bet you -- its hard to say. im pretty sure its more than one thing. and this race against time for the pinger is important. but if we dont get the pinger, well go to conventional means or extraordina...

Into the water? martin savidge is out front with the final clue. martin we use this word ping. you know, ate pretty complicated thing what were talking about. this could be incredibly significant this use of the word partial ping. >> reporter: right. as we know there were at least six pings that came from the aircraft during its flight that have been analysised by the folks at inmarsat that came up with this fact that the plane went on this southern trajectory and able to discern this plane went...

At, once its found by the search area, debris on the surface, they find the needle. its hard. we know from air france 447 the haystack found straightaway through transponder and acars, needle in terms of black boxes it took two years to find those. there are serious constraints with technology. this ping in the area, down to 20,000 feet and potentially depths of 23,000 feet. so theres discrepancies there. these things will be key. these are whether or not found debris field 447. >> many more hur...

It came so quickly after a full ping that somehow half a ping is associated with the final event of that airplane. what is it we dont know. one theory is the engines that generate electricity could have run out of fuel as we believe they did and once they did the power in this airplane stopped. was interrupted. at least for a moment. but then theres something called a little propeller that pops up and the wind motion from the airplane would generate. your cell phone shuts down from the moment yo...
