Michele M. Heidenberger, 57, a flight attendant on the plane that struck the Pentagon, worked for the airline for 25 years.
Family members said she was trained five years ago in how to deal with a hijacking. "Knowing Michelle, she was probably the one who would have approached them first and said you can't go into the cockpit," said sister-in-law Betsy Heidenberger.
