On Monday, Australian officials described the latest pings detected in the search for Malaysia Flight 370 as their best lead so far. But since then, search crews have failed to relocate them. (Via U.S. Navy )

Over the weekend, search crews picked up signals using a towed pinger locator deployed on the Australian vessel Ocean Shield. Those pings, they said, were consistent with the type of signals that would have been sent out from an airplane's voice and data recorders. (Via U.S. Navy, ITN)

Problem is, search crews haven't picked up any more pings since Sunday. Now, 14 planes and 14 ships are searching an area in the Indian Ocean about the size of New Mexico.  

And officials are describing the search as a race against the clock. The batteries that power the pingers only last about 30 days. It’s now been 32 days since the MH370 disappeared. 

If the batteries do expire, experts say search crews are really only left with one option — scouring the ocean floor inch by inch. And that’s a process that could take years.

For some perspective, it took two years to find the flight recorders from Air France Flight 447's crash in 2009.
