Explosive experts Dr. Paul Worsey and Dr. Braden Lusk learn how blasters use cutting-edge technologies to take down structures in tight spaces. Paul travels to Glasgow, Scotland, where explosive engineers are attempting to demolish two high-rise towers that sit less than 25 feet from a major commuter rail line. Later, Paul and Braden check out another blast -- the demolition of an old bridge in Pennsylvania that’s just a few feet from its multi-million dollar replacement.
