While most of Building 7 of the World Trade Center was evacuated around the time the South Tower was hit, if not earlier (see (9:03 a.m.) September 11, 2001), firefighters now find three individuals who have become trapped inside it, and lead them out of the building. [National Institute of Standards and Technology, 6/2004, pp. L-18; National Institute of Standards and Technology, 9/2005, pp. 109-110] Among these individuals are Barry Jennings, a City Housing Authority worker, and Michael Hess, New York’s chief lawyer who is also a longtime friend of Mayor Rudolph Giuliani. The two had gone up to the 23rd floor emergency command center of the Mayor’s Office of Emergency Management after the first attack occurred, but found it empty (see (Shortly Before 9:03 a.m.) September 11, 2001). [New York Times, 11/21/1997; Associated Press, 9/11/2001; Giuliani, 2002, pp. 20-21 and 244; Dylan Avery, 2007] They then headed downstairs but became trapped around the eighth floor by smoke and debris that filled the staircase. After breaking a window and calling for help, they were spotted by firefighters outside. When the firefighters go in, they also find a security officer for one of the businesses based in the building, who is trapped on the seventh floor by the smoke in the stairway. This officer headed up the building after the South Tower collapsed at 9:59, to check that all his personnel had left there (see (Shortly After 9:59 a.m.-12:10 p.m.) September 11, 2001). All three men are escorted out of the building.
