It's getting harder for a plane to vanish and not be found

Nearly 3 years after a Malaysian airliner vanished, it's still possible, if unlikely, for a plane to disappear. But that's changing with new satellites that will soon allow flights to be tracked in real time over oceans. New international safety standards also begin to kick-in beginning next year, although the deadline for airlines to meet most of the standards is still 4 years away. Even then, it could be decades before the changes permeate the entire global airline fleet because some of the requirements apply only to newly manufactured planes. But Atholl Buchan, director of flight operations at IATA said a repeat of MH370 is "highly unlikely" since many airlines have already increased their efforts to keep tabs on planes over open ocean where they are beyond the reach of land-based radar. <br/>
