Memories from Ground Zero, 19 years after 9/11: "If they asked me to go again, I would do it immediately."

19 years ago, Philadelphia Police Sergeant Greg Masi was sent to New York City. America had been attacked, two planes had just flown into the Twin Towers, and Philadelphia wanted to help New York. At Ground Zero, Sgt. Masi found thousands of people working together to rescue survivors, and to recover victims. He experienced sights and smells he'll never be able to forget. And he says that even though many of the 9/11 first responders who are still with us are fighting illnesses and cancers from the work they did 19 years ago, if he was asked to do it all over again, he'd go immediately.
