New CDI video demonstrates the artistry of the explosive engineer.
According to the YouTube write-up, this video shows Controlled Demolition, Inc. (CDI) of Phoenix, Maryland, USA (acting as Implosion Subcontractor to Hardin of Cypress, Florida) performing the successful explosives felling of four catalytic cracker units ranging from 81 feet to 131 feet tall at the former Arizona Chemical Plant in Port St. Joe, Florida at 9:50AM on Friday, March 19, 2010.
But watch it from the 56 second mark, and you actually see the artistry behind the delays as the four towers are laid down. Very nice.
