GPS May Be No Help in Finding Missing Malaysia Airlines Jet

No one yet knows what happened to Malaysia Airlines flight 370. Hamilton said it’s possible the pilot or someone else turned off the transponder, or that the plane was destroyed in a sudden, violent event that also knocked out the tracking system.

There are also secondary radar systems, but Hamilton said those have some dead zones, particularly over large bodies of water.

William McCabe, president of the aviation safety consultancy The McCabe Group, said it’s very rare in the modern era for air traffic controllers and others not to know exactly where an aircraft is at all times, because of the overlapping technologies and procedures designed to make flying safe.
