[As it is known, any real deep underground nuclear explosion will create a cavity beneath the Earth’s
surface – by vaporizing rock or soil from among its immediate surroundings. Considering that Manhattan
was built on granite rock, demolition engineers calculated that this particular 150 kiloton explosion would
create an underground cavity of about 100 meters in diameter (ideally, the cavity should extend itself by
50 meters to any direction from an actual underground position of the nuclear charge – in a professional
nuclear jargon called “zero-box”).
The cavity was supposed to reach to the end of its upper sphere, the lowest underground level of the
Tower only, but without reaching the Earth’s surface. In such a case, there was not supposed to be any
radioactively contaminated soil thrown away to the surface as a result of such a nuclear explosion. Thus,
the radioactive contamination of the surroundings would be limited to only that caused by some
radioactive gases escaping the cavity to the earth’s surface. Of course, there was supposed to be neither
any air-blast wave, nor any radiation, in either visible or in invisible spectrums, nor any Electromagnetic
Pulse – since all these well-known destructive factors belong only to an atmospheric nuclear explosion,
but not to one conducted deep underground.]
