Malaysia Airlines Flight 370: 2 new signals in search area buoys hope By Ed Payne and Greg Botelho, CNN April 9, 2014 -- Updated 0356 GMT (1156 HKT)
(CNN) -- In a sea of uncertainty, two bits of good news emerged Wednesday. The Australian ship Ocean Shield picked up fresh signals that officials hope are locator beacons from the data recorders of the missing Malaysia Airlines Flight 370. The ship had first picked up the underwater pulses Saturday. But then, for the next three days, nothing.
On Tuesday, the ship once again reacquired the signals. That's four signals in the same broad area: two on Saturday; two on Tuesday. "I believe we are searching in the right area but we need to visually identify wreckage before we can confirm with certainty that this is the final resting place of MH370," Houston said. The second piece of good news? Authorities analyzed the signals picked up Saturday and determined they were not of natural origin and was likely sourced from specific electronic equipment. "They believe the signals to be consistent with the specification and description of a flight data recorder," Houston said. Signals getting weaker Wednesday is Day 33 in the search for Malaysia Airlines Flight 370, which went missing March 8. It was carrying 239 people. Authorities haven't given up trying. Instead, they are pinning their hopes on the so-pings. But time is not on their side. The batteries powering the flight recorders' locator beacons are certified to be working for 30 days. Stored in a plane's tail, they are designed to begin sending off distinct, high-pitched signals as soon as they come in contact with water. "The signals are getting weaker. Which means we're either moving away from the search area or the pinger batteries are dying," Houston said. The first signal, at 4:45 p.m. Perth Time on Saturday, lasted 2 hours 20 minutes. The second, at 9:27 p.m. Saturday, lasted 13 minutes. The third signal was picked up Tuesday at 4:27 p.m. That lasted 5 minutes 32 seconds. The fourth, at 10:17 p.m. Tuesday, was 7 minutes long. "It's certainly encouraging that more signals have been detected," Pentagon spokesman Adm. John Kirby told CNN. "There is still much work to do, however." Four reasons to believe; six reasons to doubt
Navio Australiano captou no sábado pings consistentes com os de uma caixa preta no sábado e na terça feira
Oficiais australianos estão mais confiantes que irão conseguir encontrar o avião, ou o que sobrou do mesmo em um futuro não distante
Os sinais estão enfraquecendo, o que significa uma das duas: A bateria está acabando ou eles estão se afastando.
