Recovered unbroken glass windowpane.
Almost all of the more than 40,000 windows in the Twin Towers shattered on September 11, 2001. Only one windowpane, from the 82nd floor of the South Tower, is known to have survived intact. Jan Szumanski, superintendent for Tully Construction at Ground Zero, discovered this unbroken pane of glass still set within a fragment of the South Tower facade that landed on Church Street. He extricated the glass and was aided in its preservation by Joseph Carsky, Tully’s chief engineer.
