Search area for Malaysia Airlines Flight 370 focused on area west of Australia

Much has been made about the reprogramming of Malaysia Airlines Flight 370's flight track.

On March 8, the flight departed Kuala Lumpur at 12:41 a.m.

Sometime before 1:07 a.m., authorities believe the jet's flight path was reprogrammed.

And 12 minutes later, at 1:19 a.m., someone in the cockpit uttered the last words heard from the plane, signing-off to air traffic controllers "All right, good night."

Flying low? Burning object? Ground witnesses claim they saw Flight 370

Now, the search for the flight is becoming a race against time. The so-called black box runs on a battery that allows only allows it to transmit a signal for 30 days.

How close do investigators need to be to the black box in order to pick up its signal?
