“Responding to September 11” is one of the George W. Bush Presidential Library and Museum's most poignant, permanent exhibits; displaying a global map of terrorist attacks, news footage, the bullhorn the President used to address First Responders at Ground Zero, and a port authority officer’s badge that the President carried every day. A 22-foot, pulverized steel beam from the World Trade Center stands next to a wall carved with the names of victims of the attack.
The New York Port Authority donated this jagged, twisted beam from the World Trade Center, which weighs 1.85 tons, to the George W. Bush Presidential Library and Museum. It arrived in Dallas in 2011.
Engineers who have studied the steel — known as a C-11 panel — say it is the remnant of a triple-beam and crossbeam section from upper floors of the World Trade Center.
