The sound was that of a car crashing into an obstacle—the noise of glass and metal, only much, much louder. The tower shook violently, pushing south; then it came back. Tad Hanc didn’t need to be a civil engineer, which he was, to know that the tower was ten feet out of plumb. He could see the plaza sidewalk abutting the tower wall a thousand feet down. He thought the building was going to snap, so out of plumb it was. As it swung back north, he thought it would stop; however, three more times the tower continued to swing—back and forth, back and forth, back and forth.
