SEAoNY Summary of Identified WTC Steel Pieces at Salvage Yards as of March 15, 2002.
So that we can learn from the tragedy of September 11 (the pathetically small number of) 146 pieces of steel, were saved for future study. Of course, those responsible for September 11, want us to learn nothing.


L denotes the length of the piece in question.
