Metal Fatigue Believed to be Cause of Deadly Southwest Airlines Explosion

Investigators say the woman who died in the Southwest Airlines deadly explosion was partially sucked out of the plane.

The National Transportation Safety Board believes metal fatigue caused an engine fan blade to break mid-flight, ripping through the engine.

The plane was 3,300 feet in the air, traveling from New York to Dallas, when debris blasted into the wing and through a cabin window.

When the window burst, passenger Jennifer Riordon was partially sucked out of the plane.

Other passengers pulled her back in and tried to do CPR.

She died from blunt force trauma to the head, neck and torso.

Southwest says the 18-year-old plane was inspected just two days before the accident.

Now the NTSB is reviewing its maintenance history.
