Many Americans were taught that the U.S. mainland was not attacked during WW2. But it was. Between 1944 and 1945, the Japanese launched more than 9000 bomb-rigged balloons across the Pacific, resulting in tragic deaths in Oregon. These lethal “Fu-Go” bombs reached as far east as Indiana and as far south as Texas...but only 300 have ever been found, leaving potentially thousands of deadly bombs scattered across the US. For the first time ever, an investigation is launched into the hidden history of this attack, with a high-tech hunt for the unexploded remnants.
