The order in which victims’ names will appear on the 9/11 Memorial may change. Originally, Michael Arad, the designer of the “Reflecting Absence” memorial, proposed listing the names in random order to echo the chaos of 9/11. Under a new plan, announced by Mayor Michael Bloomberg, chairman of the World Trade Center Memorial Foundation, the names of the 2,979 killed on 9/11 and in the 1993 World Trade Center bombing will be arranged in 10 groupings according to the tower in which they died or the plane on which they traveled. Within each category, names will still be randomized, although foundation president Joseph Daniels said families could request that loved ones who died together on a plane or in a building be listed together.
