Caught on Camera PA Tower Implosion

Bethlehem, PA. (CBS) - Martin Tower, the former world headquarters of Bethlehem Steel in Pennsylvania was imploded Sunday morning.

Bethlehem Steel went bankrupt in 2001, and the 21- story tower has been vacant for a decade. But it still remained the tallest building in the Lehigh Valley area.

The tower is being imploded to make way for new development.
