Actually, every tower with a WTC prefix was destroyed or significantly dustified on that day - most people don't know that!

In addition, Bankers Trust building, which had a hole in its WTC facing side, not significantly caused by falling debris, had to be disassembled after lengthy attempts to repair it. This was due to Charge Clusters (Kenneth R. Shoulders) used to effect the dustification of the buildings, had contaminated Bankers Trust - when they tried to add new steels - they rapidly rusted (since the charge clusters are far more electronegative than the normal electrons they replace leading to rapid oxidation).
