حول هذه الحلقة

The remarkable story of how the landmark New York City skyscraper was constructed during the depths of the Depression. Requiring 10 million bricks and 60,000 tons of steel beams and using a revolutionary technique to hold the steel girders in place–hot rivets–the world’s tallest building was completed four months ahead of schedule.
