(CNN) – It's the start of another search day in Australia, were as many as 14 planes will take off looking for Malaysia Airlines Flight 370.
For the ships involved, it's a round-the-clock process. Two ships detected signals that could be the pings from the plane's black boxes – although over 300 miles apart, and just as the batteries for the flight data and cockpit voice recorders were expected to run out.
It's almost too good to be true.
Those ships have split Tuesday's search area, looking for confirmation that the signals picked up were what they are looking for.
Could this be a step towards some finality for the families, or just another false alarm?
CNN's Tom Foreman reports.
(CNN) – With so much in flux over the past 32 days in the search for Malaysia Airlines Flight 370, one thing that has remained constant is that Malaysian officials just can't seem to put out a clear message regarding the investigation into the plane's disappearance, and what happened to the 239 people on board.
For those so desperate for answers about their loved ones, the mixed messages have caused increasing frustration, not to mention a growing lack of trust.

(CNN) -Russia took Crimea, but the story doesn't end there.
Pro-Russian protesters are now battling for cities in eastern Ukraine, barricading themselves inside government buildings, and claiming independence in what the country's prime minister calls chaos "scripted" by the Kremlin to justify an even bigger land grab.
The White House now says some of these protesters are likely on Moscow's payroll.
Russia denies having anything to do with the pandemonium. But the White House is threatening new sanctions if President Vladimir Putin keeps pushing.
And all the while, tens of thousands of Russian troops remain on the border.
Former U.S. Under Secretary of State Nicholas Burns, now a professor at Harvard, joins CNN's "The Lead with Jake Tapper" to discuss.
(CNN) – Searchers are racing to re-discover signals which could be from the pingers on Missing Malaysia Airlines Flight 370's black box recorders.
The frantic search to pick up those signals again has been going round the clock, because the pinger batteries are running out, if they're not dead already.
"As optimistic as we were, to even get any detection, really, is pretty miraculous," said Commander William Marks, spokesman for the Navy's 7th fleet, which is overseeing the U.S. role in the search.
"Without any leads this area would simply be an incredibly huge area to try to search," said Marks.
(CNN) – Searchers say pulse signals detected in the Indian Ocean provide the best hope so far for finding Malaysia Airlines Flight 370.
Separate pings were detected by an Australian ship and a Chinese ship. But the pings detected by Australia's ship were at a lower frequency than the standard for flight data and cockpit voice recorders' pingers.
Meanwhile, the reliability of the information from the Chinese ship is in doubt for many reasons.
So is hope fading yet again?
Thomas Altshuler, vice president of Teledyne Marine Systems Thomas Altshuler, the company that manufactures the ping detection equipment on the Chinese ship, and Chris Portale, director of Dukane Seacom, the pinger manufacturer discuss.
