Andrew Johnson joins Richard to discuss his latest research. Dr Wood's book, "Where Did the Towers Go" shows that the twin towers were disappeared using an energy weapon. One of the peculiarities of the 9/11 aftermath was the presence of iron micro-spheres. These are tiny spheres of pure iron found in the dust, which, if the official story is true should not be there. Iron micro-spheres of about the same size have also been discovered in the ground by scientists where crop circles have formed. Is it possible there is a link between the creation of unexplained crop circles and the energy weapon used to destroy the world trade centre? Further evidence also points to a possible link between the 9/11 weapon and crop circle formation. Could this link provide a long awaited explanation for many of the non planked (sometimes called "genuine") crop circles?
