DALLAS (AP) — The “Leaning Tower of Dallas” has endured scores of blows from a wrecking ball. The social media sensation born when a part of an 11-story building survived implosion is set to come down. Dozens of people gathered in the Texas city’s downtown to watch Monday as a crane was used to batter the former Affiliated Computer Services building. The structure inspired jokes and comparisons to Italy’s Leaning Tower of Pisa when a Feb. 16 implosion failed to bring down its core. Some onlookers were nonplussed by the ball that began swinging Monday morning.
