Possible debris of Flight 370 investigated in Indian Ocean

Searchers racing against time: if there is something in the ocean off Australia, and it's the so-called black box that records flight data, time is the enemy. It could be just hours before that box stops transmitting a pinging tracking signal. And the water in the southern Indian Ocean can be 13,000 feet deep – more than ten times the height of the Empire State Building.

“It becomes a situation of trying to hear a very tiny signal in a really complex background noise,” said Applied Research in Acoustics specialist Jason Summers. “And that's a hard problem no matter what…made only worse by this being very deep, which makes the signal worse.”

But the ocean isn't the only place being searched for clues; FBI agents are piecing together some of the information that was deleted from the hard drive of the pilot's flight simulator. Agents are looking for any signs of unusual flight paths that could help explain where the plane went. Meanwhile, the families of the 239 missing passengers are getting more and more frustrated – many of them complaining about the lack of transparency. 

“The way that the international investigators have been working together is kind of like a bunch of teenage girls running around a locker room all trying not to show each other what they've got,” stated Sarah Bajc, partner of MH-370 passenger. “It's kind of a false sense of modesty, and if we would have had a little bit more disclosure and a little bit more open cooperation earlier in the cycle, we might be at a completely different place now.”

One U.S. Navy plane and four Australian planes are looking for the debris field, but it's a long way from land. The search area is more than 1,400 miles from Perth, Australia, and planes only have about two hours for each search before they have to turn around to re-fuel.
