Please listen to William Rodriguez at 7m23s!!!

He was an employee at the Twin Towers for over 20 years and he passionately describes the bomb that went of in the basement or the lower floors before the 1st plane hit the tower! This includes seeing people with their skin hanging off their face and body.
