Thacher Proffitt & Wood real estate partner Donald Simone was at his desk on the 40th floor of the World Trade Center's south tower early on 11 September, 2001, pushing to close a deal, when United Airlines Flight 175 crashed into the building about three dozen floors above.

"When it hit, my whole office moved," Simone recalls. With the electricity off and ceiling tiles falling, he made his way to a stairwell and then to safety.
