Underground and its similarity to 9/11

In Ken'ichi  Yamazaki story reminded me so much about 9/11. After everything was going on with the gas attack, Yamazaki saw the news of the terrorists and recognized one. With that said he was lucky that he ad least knew about the person and knew what he could expect especially if he gone to school with him. The story about Yamazaki was horrible story is a terrorist attacking the subway system in Tokyo reminded me a lot on the 9/11 incident because of horror of visualizing two of New York's most important led alone tallest building falling on innocent people after being crashed by two hijack air liner holding passengers in full capacity and used for terrorizing the world.
