“[T]here was just an explosion [in the south tower]. It seemed like on television [when] they blow up these buildings. It seemed like it was going all the way around like a belt, all these explosions.”

                                                                                                                 --Firefighter Richard Banaciski

“I saw a flash flash flash [at] the lower level of the building. You know like when they demolish a building?”

                                                                                                                 --Assistant Fire Commissioner Stephen Gregory

“[I]t was [like a] professional demolition where they set the charges on certain floors and then you hear 'Pop, pop, pop, pop, pop'."
