in-flight data recorder and voice recorder. but the problem is, that giant microphone, as powerful as it is, can only hear for about a mile around. we have to be within a mile of the black box to get a signal. and with only about a week of battery life left and still no clear leads as to where 370 may be in this massive indian ocean, the technology pretty much will be useful unless we can narrow down that information. there s other technology oh this ship as well. an underwater drone that can scan the floor of the ocean looking for debris but again that can only cover about 50 square mile as day and we re talking about a search area that is well over 100,000 square miles. the task of finding this is still too difficult for even technology like this. nonetheless, the journey for the ocean shield, if we can get it close to the area and then if one of the search planes or one of the search boats spots debris, something connected to flight 370, this ship will be
flight 447, we had better information of where the aircraft went in the water. we supported with the locator search. the pingers were nonfunctional. it then took over two years conducting sonar searches from autonomous vehicles to locate the debris. it can be a long effort. this could be long. that black box pinger could run out of battery for the next week. it could take three days to reach the search zone. much of the conversation is focussed on what needs to change in the airline industry and the way airline beings are invest gated. willi william mcghee is a contributor for attention all passengers and how to reclaim our chis. sir, welcome.
confirming the prime minister s grim announcement. none of those on board survived. the news just too much for the grief-stricken families. others fainting and taken out on stretchers. march 28th, three weeks into the search after days of scouring the section of the southern indian ocean, search crews find out they have been looking 23489 wrong spot. the search zone shifting by hundreds of miles. as soon as the search moved, possible debris is spotted and another, more and more sightings, most turning out to be trash. as the satellite and visual sightings come in and the search continues, the world is still waiting for the words, the plane has been found. cnn, atlanta. amy, thank you. bad weather made it tough for these pilots searching for the missing plane.
tremendous job. the australians have this now and they are doing quite a good job. as for the planes searching for debris, the families of flight 370 search for information. like the team, loved ones are coming up independent. families were given a technical briefing, but officials deny the request for maintenance and repair record, citing the ongoing investigation. outside of the briefing, officials also declined to meet demand from the families. an apology. many families are outraged that malaysian authorities said it crashed with no response to back it up. the response is it s not helping. live for us in kuala bumpure. some families flew from chine to meet with airline and government officials. did they get that apology?
to find the debris in the current? read the ta statement of what they said last night. they said we want that pinger locator in position so the moment we find the debris, we can get to it. we don t have to spend two or three days waiting for it to get there. i m sure families would be using the word waste. it was wise to deploy assets and get them going. i think now that additional requests have come in the united states for more assistance in assets. i think australia taking over and setting up the joint task forces brilliant. that s what they needed to do. they will be ready to g. thank you both so much. coming up, we will go back inside the virtual room of the most difficult area of the search both above and below water. stand by for that. also ahead, is north korea
