very intresting thread

anybody know about Luigi Romersa travel in germany in late 1944? He was sent by mussolini to visit Germany secret weapons factories and Peneemunde reserach facilities, but not only. He also tell about an experiment took place in a baltic sea island (Rugen) in the night between 11 and 12 october involving a new kind of explosive: the "bomba disgregatrice" (in english: bomb that reduce to atoms... i think ) actually the first atomic bomb experiment. The episode, described in his book, is controversial... is it true or is a propaganda attempt in order to give trust in the "finaly victory", soo far in the 1944?
