I saw countless hours of arguments between people advocating for A DEW or a nuclear demolition and sadly, too many people wanted to argue instead of research. Dimitri Kalezov, Russian nuclear arsenal specialist, made a decent case for the towers being dustified by a chain reaction caused by nuclear demolition. The US 'Operation Plowshare' was a program in the 1960s to repurpose nuclear weapons technology into other areas and he claims it was common knowledge in certain circles that the WTC towers were designed with demolition by specialised nuclear in mind. New York planning code requires structures to be able to be demolished before they can be constructed and the scale of those towers meant that typical approaches could not be used - he says that this is why they used nuclear demolition by design.
