BETHLEHEM—Sixteen thousand tons of Bethlehem Steel collapsed in a matter of seconds Sunday as a demolition crew imploded Martin Tower, the defunct steelmaker’s former world headquarters.
Crowds gathered to watch the demolition of the area’s tallest building, a 21-story monolith that opened at the height of Bethlehem Steel’s power and profitability but had stood vacant for a dozen years after America’s second-largest steelmaker went out of business.
