ABM Industries' Undercover Boss, Henrik Slipsager, Revisits 9/11

There aren't many adults in the United States who can't recall exactly where they were when the planes flew into the World Trade Center on 9/11. President and CEO of ABM Industries Henrik Slipsager, this week's Undercover Boss, was in San Francisco, desperately trying to contact his family at home in New York. Two of the workers who participated with him in an 'Undercover Boss' segment were at Ground Zero.
