Linda Lopez was at work at the Fiduciary Trust Company on the South Tower's 97th floor when the first plane crashed into North Tower, sending a fireball past their window and radiating a heat that she said felt like being sunburned. There was quickly a sense of confusion: Was it a bomb? Were the rumors that it was a plane crash true? Should people in the South Tower ignore the advice coming over the public address system to stay put and evacuate instead? Lopez felt she had to get out. She had reached only as far as the 61st when she was thrown against a wall as the second plane crashed into the floors above her. Taking off her shoes, she continued to head down the stairs, passing firefighters heading in the opposite direction. She ran barefoot out of the building, across broken glass and other debris. "Lady, your feet are bleeding," someone said to her as she paused a few blocks away in relative safety. She put her shoes back on, and began learning the details of what it was she had just escaped from. he museum, which occupies seven stories below the ground of the World Trade Center site--is still being built at the site of the fallen towers.
