Nuclear demolition of the WTC. The author of this article used to be a commissioned officer in the Soviet military unit 46179, otherwise known as the "Special Control Service of the 12th Chief Directorate of the Defense Ministry of the USSR". The 12th Chief Directorate itself was an organization responsible in the Soviet Union for the safe-keeping, the production control, the technical maintenance etc. of the entire nuclear arsenal of the state. The Special Control Service was responsible for detecting nuclear explosions and was responsible for the observance of all international treaties related to nuclear testing. It is especially important to note the existence of the so-called “Peaceful Nuclear Explosions Treaty” of 1976 between the USSR and the United States of America. In accordance with this Treaty, all parties were obliged to inform one another about all nuclear explosions intended for non-military purposes.
During my military service in the abovementioned organization at the end of the ‘80s, it came to my knowledge that there was a so-called “emergency nuclear demolition schema” built into the World Trade Center Twin Towers in New York. The actual nuclear demolition schema was based on huge thermo-nuclear charges (about 150 kilotons in TNT yield) which were positioned about 50 meters below the lowest underground foundations of each of the Towers. It was strange to me by then and, to be honest; it was hard to believe that US authorities would be crazy enough to demolish buildings in the middle of a populated city using underground nuclear explosions.
However, as I understood it correctly, nobody had ever actually planned to demolish the World Trade Center in such a way. It was merely a means to get around the bureaucracy: such a nuclear demolition schema had to be built into the Twin Towers not to get them demolished, but to get permission to build them in the first place. The problem was that the then building code of New York (as well as that of Chicago) didn’t allow the Department of Buildings to issue permits to build a skyscraper unless its constructor could provide a satisfactory means by which he could demolish the building either in future, or in the case of emergency. Since the late ‘60s (when the Twin Towers were first proposed) this type of steel-framed buildings was a totally new concept and nobody knew how to deal with them in the sense of demolition. Given that traditional (“conventional”) controlled demolition methods were applicable purely to older-style buildings, they had to come up with something new for the incredibly strong steel Twin Towers that would convince the Department of Buildings to issue permission for their actual construction. And the solution was indeed created: nuclear demolition.
