Ironworkers James Brady, left, and Billy Geoghan maneuver a steel beam as it is hoisted by crane to the 104th floor of 1 World Trade Center, Thursday, Aug. 2, 2012 in New York. The beam was signed by President Barack Obama with the notes: "We remember," ''We rebuild" and "We come back stronger!" during a ceremony at the construction site June 14. Since then the beam has been adorned with the autographs of workers and police officers at the site. The beam will be sealed into the structure of the tower, which is scheduled for completion in 2014. (AP Photo/Mark Lennihan) less
