[25] Many of the recovered balloons also had a high percentage of unexploded plugs, caused by failure of their batteries or fuses. This discovery greenlighted the mass production of 10,000 balloons in preparation for the winter winds of 1944 and 1945. "It .

By then, the balloons would be expected to reach the mainland; an estimated 1,000 out of 9,000 launched made the journey. The bombs were ineffective as fire starters due to damp conditions, causing only minor damage and six deaths in a single civilian incident in Oregon in May 1945. Records uncovered in Japan after the war indicate that about 9,000 were launched. The first battalion included headquarters and three squadrons totaling 1,500 men in Ibaraki Prefecture with nine launch stations at tsu. Word of the Bly, Oregon, deathsand the strange mechanism that had killed them was overshadowed by the dizzying pace of the finale in the European theater. The currents had been investigated by Japanese scientist Wasaburo Oishi in the 1920s; in late 1943, the Army consulted Hidetoshi Arakawa of the Central Meteorological Observatory, who used Oishi's data to extrapolate the air currents across the Pacific Ocean and estimate that a balloon released in winter and that maintained an altitude of 30,000 to 35,000 feet (9,100 to 10,700m) could reach the North American continent in 30 to 100 hours.

Arakawa further found that the strongest winds blew from November to March at speeds approaching 200 miles per hour (320km/h).

The idea of the balloon bombs returned when Japan sought to retaliate after the Doolittle Raid, which revealed Japan to be vulnerable to American air attacks.

Matthias recalled that although the Hanford plant did lose about two days of production, we were all tickled to death this happened because it proved the back-up system worked. The officials determined that the balloon was of Japanese origin, but how it had gotten to Montana and where it came from was a mystery.".

[24] The most tactically successful attack took place on March 10, 1945, when one of the balloons descended near Toppenish, Washington, colliding with power lines and causing a short circuit that cut off power to the Manhattan Project's production facility at the state's Hanford Engineer Works. These animals can sniff it out. "The envelopes are really amazing, made of hundreds of pieces of traditional hand-made paper glued together with glue made from a tuber," says Marilee Schmit Nason of the Anderson-Abruzzo Albuquerque International Balloon Museum in New Mexico.
