A 21-storey building in downtown Richmond, Virginia, was demolished in a spectacular implosion.
The former Dominion Energy office tower came down in just 20 seconds.
The tower, completed in 1978, had been vacant since last autumn when the company relocated its offices to a new building. Report by Avagninag. Like us on Facebook at http://www.facebook.com/itn and follow us on Twitter at http://twitter.com/itn
