The Japanese military had been tinkering with the idea of a balloon weapon since 1933, considering designs which would drop bombs or shower propaganda leaflets behind enemy lines after flying a fixed distance, as well as a balloon large enough to carry a soldier. Japanese officers later told the Associated Press that they finally decided the weapon was worthless and the whole experiment useless, because they had repeatedly listened to [radio broadcasts] and had heard no further mention of the balloons. Ironically, the Japanese had ceased launching them shortly before the picnicking children had stumbled across one. Chinese spy balloon sparks echos of Japanese balloon bombs during WWII They called it Operation Fu-Go. To this day, historians believe not all balloons have been recovered. Their Proposed Airborne Carrier research and development program explored several ideas, including the initial idea of balloon bombs, according to Robert Mikesh. The program was cancelled by the Navy. [20] The best time to launch was just after the passing of a high-pressure front, and wind conditions were most suitable for several hours prior to the onshore breezes at sunrise. Japanese Balloon Bombs (Fu-Go Weapon) But the lack of a governed outcome was tempered by the fact that no Japanese troops were at risk. The Japanese balloon bomb, in all its terrible splendor. When does spring start? They emphasized that the balloons did not represent serious threats, but should be reported.

When the balloons made landfall, there were no obvious clues as to where they originated. Between 1944 and 1945, Japan launched more than 9,000 bomb-rigged balloons across the Pacific Ocean. The tsu site featured its own hydrogen plant, while the second and third battalions used hydrogen gas manufactured at factories near Tokyo. What if we could clean them out? When Col. Sigmund Poole, head of the U.S. Geological Survey military geology unit at the time, was given sand from one of the balloon's ballast bags, he is alleged to have asked, "Where'd the damn sand come from?". Hyde's wild ride: New documentary features former Box Elder sheriff who The final balloon design was 33 feet (10m) in diameter, and had a gas volume of 19,000 cubic feet (540m3) and a lifting capacity of 300 pounds (140kg) at operating altitude.

[40] As predicted by Imperial Army officials, the winter and spring launch dates had limited the chances of the incendiary bombs starting forest fires due to the high levels of precipitation in the Pacific Northwest; forests were generally snow-covered or too damp to catch fire easily. Eventually American scientists helped solve the puzzle. The balloons, or "envelopes", designed by the Japanese army were made of lightweight paper fashioned from the bark of trees. Japans bizarre WWII plan to bomb the continental U.S. by high-altitude balloons claimed its first and only victimsan Oregon church group in 1945. During the day, heat from the sun increased pressure, risking the balloon rising above the air currents or bursting. Hisscholarly report on these Fu-Go balloonsis a definitive work on this obscure topic. Some balloons in each of the launches carried radiosonde equipment instead of bombs, and were tracked by direction finding stations in Ichinomiya, at Iwanuma, Miyagi, at Misawa, Aomori, and on Sakhalin to estimate the progress of the balloons towards North America. The Bly incident also struck a chord decades later in Japan. Your Privacy Rights Map by Jerome N. Cookson, National Geographic; source: Dave Tewksbury, Hamilton College.
