We are lead to believe that not only did the 757 penetrate the outer wall, but continued on to penetrate separate internal walls totaling 9 feet of reinforced concrete. The final breach of concrete was a nearly perfectly cut circular hole (see below) in a reinforced concrete wall, with no subsequent damage to the rest of the wall. (If we are to believe that somehow this aluminum aircraft did in fact reach this sixth final wall.)
