Perfect photograph depicting the core of one of the towers including the elevator shafts. On 9/11, Welles Crowther went down the South Tower from 104 to 78, carried a woman on his shoulder from 78 to 61, THEN WENT BACK UP TO 78, then down a few flights and back up to 78. Eventually, he made it down to the lobby but only after saving at least 8 people during his travels.
