Malaysia Airlines Flight 370_ Pings Not Heard Since Weekend - CNN
  4/8/2014Malaysia Airlines Flight 370: Pings not heard since weekend - CNN.comhttp://www.cnn.com/2014/04/08/world/asia/malaysia-airlines-plane/index.html?hpt=hp_t11/4 HomeU.S.WorldPoliticsJusticeEntertainmentTechHealthLivingTravelOpinioniReport (CNN)  -- The pulses that an Australian navy ship detected over theweekend from a remote location in the Indian Ocean have not been picked up since, but authorities are not letting that deter their search f or Malaysia Airlines Flight 370. We have at least several days of intense actions ahead of us,  Australian Defense Minister David Johnston told reporters Tuesday. We're throwing everything at this difficult, complex task. Investigators hope the signals were from locator beacons that wereattached to the data and voice recorders that were stored in the tailof the Boeing 777-200ER when it disappeared from radar screenson March 8.Buoyed by the hope that they're closing in on the beacons, theyreduced the search area Tuesday.Their current focus is 30,000 square miles (more than77,500 square kilometers) of the Indian Ocean, about1,400 miles (2,250 kilometers) northwest of Perth. That'sabout a third of the size of the previous search zone. Instead of looking at an area the size of Texas, we're nowlooking in an area the size of Houston, aviation expertGeoffrey Thomas told CNN.Time, however, is looming as a factor.The batteries powering the beacons, which are designedto emit signals when submerged in salt water, are certifiedto last 30 days.Tuesday marks day 32.

We need to continue ... for several days right up to whenthe point at which there's absolutely no doubt that thepinger batteries will have expired, said retired Air Chief Marshal Angus Houston, the chief of the Australianagency coordinating the search.Retired Royal Air Force Lt. Col. Michael Kay predicted thesearch for the pingers would continue for another weekand a half. We know that the batteries can last up to 40 days, Kaytold CNN. If I was Angus Houston, I would be putting the search outto at least 42, 43 (days) to make absolutely sure that the batterieshad failed. The race against time is the Number one challenge searchersface, U.S. Navy Cmdr. William Marks told CNN. We haven't quit since we initially heard these signals, he said. We've been going continuously around the clock and we haven'tbeen able to reacquire them. Searchers are still scouring the waters, but their optimism is morecautious now, he said. As hours pass, he said, our optimism isfading away, ever so slightly. What happens after the Malaysian plane's pingers die? Major challenges But the search area still presents major challenges.The location is deep, and a cyclone that packed windspeeds of more than 160 mph churned through the areatwo weeks ago, when crews were focused elsewhere inthe Indian Ocean. In doing so, it would have further spread any debris. This was an area that looked like a washing machine inthe first place, but now we know it was even worse thanthat, CNN meteorologist Chad Myers said.But Tuesday's weather was calm, with no major systemsnear where the pings were detected, said CNNmeteorologist Sherri Pugh.Four reasons to believe; six reasons to doubt Consistent signals Cheers erupted Saturday when the team aboard Australia's Ocean Shield first detected a possible signalfrom one of the plane's recorders.The Australian ship is equipped with two key pieces of U.S. equipment to scan the water for signs of the plane: atowed pinger locator and a Bluefin-21 underwater vehicle.The first detection continued for more than two hours; thesecond for about 13 minutes.The signals, detected about 1,750 kilometers (1,100miles) northwest of Perth, Australia, were consistent withthose sent by a flight data recorder and a cockpit voice recorder,  A Chinese ship has detected apulse signal consistent with themissing plane's black boxfrequency. Still, expertsexercise caution. Could the pings be a false alarm? updated 12:46 PM EDT, Sat April 5, 2014 The possibility of closure for relatives of the passengersand crew may have emergedin the form of an unconfirmedpulse signal.

They were heard in seawater about 4,500 meters(14,800 feet) deep. The audible signal sounds to me just like an emergency locator beacon, Houston said. We are encouraged that we are very closeto where we need to be. If the signals are heard again, searchers could deploy anunderwater drone to take photos to determine whether they doindeed mean the discovery of the so-called black boxes. Thatprocess could take more than a week. Until we have stopped the pinger search, we will not deploy thesubmersible, Houston said. We will not deploy it unless we getanother transmission in which we'll probably have a better idea of what's down there. Next steps in underwater search Pulses detected Teams are also still investigating pulses detected Friday andSaturday by a Chinese ship about 600 kilometers (375 miles)southwest of where the Ocean Shield is searching.The signals detected by the Chinese weren't as sustained as thosepicked up by the Ocean Shield, and the Chinese vessel's detectiongear isn't thought to be as advanced as the U.S. pinger locator.Houston said Monday that they were probably separate events.Some friends and relatives of passengers said they were keepingtheir hopes in check. Until they physically locate the bulk of the plane with the black boxintact and passenger bodies, I won't believe it, said Sarah Bajc, thepartner of American passenger Philip Wood. At a candlelight vigil in Beijing on Monday night, some relativessobbed and others bowed their heads. If the plane is there, it's there. We can't change it, the husband of one passenger said. But I am still hoping for a miracle to happen.
