A decade after the World Trade Center collapsed in a plume of fire and smoke, steel recovered from its ashes is rising at local public memorials. The Port Authority of New York and New Jersey made the steel available to communities and organizations across the country to honor and remember Sept. 11, 2001.
At left, Joan Greener, whose niece Karen Martin was the lead flight attendant on American Airlines Flight 11 that was hijacked on 9/11, is pictured in Salem with a memorial flag that lists the names of all the victims from that day. Karen's name is visible on the top line in the middle.
