Firefighters who survived twin towers collapse honor their "guardian angel"
When the twin towers collapsed during the Sept. 11, 2001 terror attacks, only 20 people who were inside made it out alive, including six firefighters and a woman they now regard as their guardian angel. On Tuesday, nearly 25 years later, the firefighters reunited in their firehouse, along with the woman's family. CBS News New York's Ali Bauman has the exclusive story.
