(CNN) Jennifer Riordan, a well-known leader and altruist from New Mexico, died Tuesday when a Southwest Airlines jet engine failed midair and its debris blew up a window.

Riordan, 43, was making her way back home to Albuquerque when a terrifying episode ensued about 20 minutes after her plane left New York's LaGuardia Airport.

Passengers had to pull her back into the plane when she was being sucked out of the broken window. She died at a Philadelphia hospital after the plane made an emergency landing, authorities said.

She died from blunt impact trauma of the head, neck and torso, a spokesman for the Philadelphia Department of Public Health said.

Hers was the first death from an in-flight incident in company history, the airline said.
