Japan Launched 9000 Balloon Bombs Across the Pacific

Between 1944 and 1945, Japan launched 9,300 paper balloon bombs using jet streams - the first intercontinental weapons system. Over 1,000 reached North America. A balloon killed Elsie Mitchell and five children in Bly, Oregon - the only enemy-inflicted American casualties on US soil. The US imposed press censorship to deny Japan targeting feedback.
