and in addition to that, we have a p-3 orion patrol aircraft and incoming p8 posiedon. the reason they are so important, they give us the longest possible range we can get. we're talking upwards of 1,000 plus miles every time they fly. they fly one long 9-hour or so flight. and over that flight they can cover 10, 11, 12,000 square miles. so when you plook at the xpans, that is the indian ocean, that's why you want the p- 3 and p-8 out there. >> i know the posiedon has the most advanced equipment. dove do they have the ability to run 24/7. >> they are not limited to daylight. they used a very advanced surface search radar and night vision and infrared. so to detect anything on the surface of the water like debris, for example, really all they need is their radar and they will pick it up. >> this is such an enormous expanse. give us a sense of challenge here now that we're talking about the indian ocean and completely different sector? >> this is a huge challenge. i think now is the time to transition. whereas before when you were in the gulf of thailand, you had relative

and the focus is with the p-8 posiedon. and that's where the u.s. will focus. >> what increased security alerts are we seeing tonight? >> the one country that has done something is israel. it is requiring airlines to identify themselves earlier than normal. you travel to israel and i have been there a number of times. it's the country with the most strict security on the ground when you are flying airplane, interrogations, questions, searches and strict procedures for airliners approaching. they have to identify themselves further on the chance that this plane has been hijacked for later use, perhaps in an attack. the u.s. and i have spoken to people on capitol hill including members of the house intelligence committee, is the u.s. considering any measures. this conceivably exposes security fears here. it presents the fact it could happen here 13 years after 9/11. including what a pilot can do in a cockpit. could the pilot turn off the transresponder. that is a possible change going forward. that is things they are looking at. you can be sure there

southern indian ocean and an international fleet will resume the search for flight 370 the pentagon's posiedonincluded in that search, scouring an area where a chinese satellite spotted what might be debris from the doomed jetliner appearing to show an object as long as 72 feet long. and a bloody take over in crimia. pro russian forces stormed a ukrainian military base, one of the last holdouts in crimya. this one day after vladimir putin signed bills officially absorbing the region into russia. now more on a special edition of "the kelly files". sts beaten, w understand. we're watching that situation unfold overnight. >>> welcome back to our kelly file special. the mystery of flight 370. for now. the focus of the search involves a patch of water more than a thousand miles from anywhere. that is just the beginning of this challenge. trace gallager has that part of our part. the reason they are focusing so heavily oint southern indian ocean is because there's no confirm of radar that it kept flying on a northward path. there's radar data that indicates that it was flying west and then south. mi

navy posiedon. yesterday's search was unsuccessful despite much better weather. better weather, the aircraft instead knew really low to the water and they used a visual search, meaning people looking out of the window looking for the debris. you can imagine, this is a very vast expanse of ocean, very rough and tough. unfortunately good news is that weather is much better but the search was unsuccessful. the plan here is to do the same. so they'll try to go in and try to go low. and see what they can see out of the windows as well as having eyes on the ground in terms of both merchant chips they'll try, also, to acquire more satellite imagery so they a better idea of where, where exactly they're looking for debris. >> we showed earlier in the program, by the way, thanks for joining us we showed earlier in the program we showed 125,000 square miles, only a small portion of the amount of ocean we're talking about here. would we have better luck, perhaps, or some professionals you're talking to in australia? saying they may have better luck if we use that imaging? ho

orion and c 130 hercules aircraft, a royal new zealand aircraft p 3 orion, a united states navy posiedontralia civil jet acting as communications relay. four of the ten are overhead as we speak with six planes flying over the area today. a further p 3 orion has been placed on stand by in western australia to investigate any reported sightings. six ships are relocating to the new search area including hma success and five chinese ships and expected to arrive in the search area by tomorrow night. additionally the chinese maritime is in the area. and safety conference we have the opportunity to do a search and rescue exercise off the ship. and policing 21 underwater vehicles have arrived in perth to assist with location and recovery of the black box. these will be fitted to australian defense vessel ocean shield which will arrive in western australia incoming days. the depth of the search area is 2000 meters and 4,000 meters. >> thank you. >> the atsb agency is working with a range of other international expert organizations to analyze available data relating to the flight of mh 370 and det
