Japanese Balloon Battle

mw2040 writes "Slate reports on a little-known method used by the Japanese during WWII - hydrogen-filled paper balloons with deadly payloads floated without a guidance-system across the Pacific. Both amazing low-tech warfare and a cautionary tale about censorship during wartime. More links (even one for our neighbors to the North) (shamelessly stolen from the article)."

    Unless you actually read a book or watched Discovery channel in the past 20 years. I've seen that on there tons of times. And I read a story about it in high school which was almost 6 years ago. Maybe little known if you only know a little?

  2. Balloon by Anonymous Coward · · Score: 5, Informative

    The BBC (or it may have been Channel 4 in the UK) did a programme about these balloons, explaining how the Japanese used the Jet Stream, and a clockwork mechanism to drop sandbags allowing the balloon to drop out of the stream once over the States - I believe many ended up in Canada.

    I heard about this in my world history classes in high school and college, in my Japanese history class (well no shit I'd hear about it there), and on several occasions since, and I've never once gone actively looking for this information.

    I think it's more well-known than most minor elements of WWII.

    Interestingly, one of these was also found in California.

    (That page says the device was taken to Moffetf Field in Sunnyvale CA, but Moffett is and always has been in Mountain View. I believe it was sometimes described as being in Sunnyvale because the military guys were sensitive to the perception of 'Mountains' being anywhere near their airship base. No reference, just remember this from many an airshow..)

  5. At least they didn't load them with bio-weapons by foidulus · · Score: 3, Informative

    The Japanese had created an interesting bio-weapon during WWII, though they only "tested" it on the Chinese. They figured out a way to create a bomb that would explode scattering plague infested fleas everywhere. It was quite an engineering marvel, even if the results were sickening(to this day, parts of rural China will still periodically get outbreaks of the plague because of these weapons labs), they figured out how to make a bomb explode without killing the fleas. However they never really used it against the Americans, maybe in fear of what the retribution would be.
    As the case with Nazi scientists, the head Japanese scientists who worked on Japan's bioweapons during the war avoided war crimes prosecutions by coming over to the US after the war to help in the new "war" against the Soviets.

  7. Re:Low technology against high technology by CastrTroy · · Score: 4, Informative

    I saw a documentary about this as to why the AK-47 beats the M-16 in real combat. It basically came down the the fact that the M-16 was a rifle with autofire capabilities, while the AK-47 was a machine gun with rifle capabilities. The AK-47 worked much better in real combat, because it almost never jammed, and was quite easy to use, which is good if you don't have time to train soldiers. The AK-47 was also a lot heavier. Which allowed it to be used much more effectively at very close range. (AKA, using it to club the guy over the head)

  9. "Balloons Of War" by LISNews · · Score: 4, Informative

    John McPhee wrote about this in The New Yorker, 29 January 1996, 52:60. It's a really neat story on how Geologists figured out where exactly in Japan the balloons were being produced based on the sand used in the ballast the ballons held to make the long float across the Pacific.
    This is how we first learned about the jet stream as well.

    I'm pretty sure the story is in Annals of the Former World, a 1996 book by McPhee, all about geeky geology stuff, but it's a really interesting read.

    Not that it worked out very well, but I still think the American's bombing method was much more interesting, and probably a little less well-known. (Though not at all arcane. The last time I mentioned it at least one fourteen-year-old already knew of it.)

  11. Jet Stream Badassity... by SuperChuck69 · · Score: 4, Informative
    The really cool part (and the science part, IMO) is that what made the baloon bomes possible was the Japanese discovery of the jet stream. At the time, no one knew it existed

    Only by coincidence did the Yanks discover that the bombs really were coming from Japan. The sand used in the sandbags was analysed and turned out very unique. However, as the Americans had done a complete survey of Japan's beaches (your granddad's tax dollars at work), they were able to narrow it down to a sand composition at a single beach in Japan.

    Curious, a couple planes were sent to investigate...

    So until 1940-whatever... No idea the jet stream existed.

  12. Mainland casualties in WWII by Zog+The+Undeniable · · Score: 3, Informative

    I thought the balloon bombs were pretty famous, simply because they caused the only casualties (from enemy action) on the mainland USA during the whole of the war. A picknicking family found one of the bombs, which hadn't gone off, and er...tampered with it until it did, killing them.

  13. Invading Canada.... by cmholm · · Score: 3, Informative
    Not taught in American schools? Depends on which school. My high school US history instructor opted to go a bit more in depth on the War of 1812, including the part where Upstate New Yorkers burned down what's now Toronto... then called it a day and marched home. It's suggested that the torching of Washington D.C. was retaliation.

    As for land grabs, while there were a number of prominent Americans that advocated annexing Canada in those days, President Madison wasn't one of them. Rather, it was rabble rousers west of the Appalachians and south of Mason-Dixon.

    Would we have given a damn about their invasion of the Philippines, Burma etc. and the Rape of Nanking if it were not for Pearl Harbor? I think not.

    The US applied economic sanctions on Japan prior to Pearl Harbor. Some in the US government in 1931 were in favour of actions in response to the invasion of Manchuria, but Hoover decided against them. In July 1939, the Roosevelt administration abrogated the Japanese-American Treaty of commerce, and in July 1940 introduced a licensing system for exports of petroleum and scrap iron to Japan. In July 1941, the US froze all Japanese funds in the US, and suspended all trade.

    You know nothing about history. Stop pretending you do. Japanese Imperial aggression was legendary in the mid to late 30's. Only after Japan had to fight a war on two fronts (sound familiar) and its military blunders at Midway among other places did the tide turn in favor of the United States. Japan's interest in world conquest as an imperial power was more than well known, it was practically trumpeted. Considering their pact with the Germans, it was only a matter of time that it would've been a desperate fight for our very survival. Why wait until that happens? You seem to think it'd be more "honorable" or "moral" to wait until we were the last free nation on earth to stand against the Nazis and Japanese. That's stupid. Thank your grandparents for not being as dumb as you, or you'd be speaking German right now and praising the fall of the zionist state of America.

    My rhetorical question is, how can you know nothing about the size and scope of Japanese aggression in the Pacific? In 1945, the Japanese were sitting on their island, defeated by the Allies, refusing to surrender. Hiroshima and Nagasaki were their incentive.

    Your view of history sickens me. Creep.

  16. more secret weapons: Grimsby Butterfly Bomb by Willard+B.+Trophy · · Score: 3, Informative
    News blackouts during wartime aren't just a US thing.

    On June 24 1943, the English fishing port of Grimsby was bombed with experimental "butterfly" anti-personnel bombs. A total news blackout on this raid caused the Luftwaffe to abandon butterfly bombs after one raid, since they thought that the devices were ineffective. Quite the opposite was true -- many people were killed or injured by the butterfly bombs. Unexploded devices were still being found in and around Grimsby until quite recently.

    In March 1941, the Scottish town of Clydebank was razed by German bombers. The first news that people in the nearby city of Glasgow heard of it was when survivors started walking in from Clydebank.

  17. Re:Hadn't heard about casualties by nyekulturniy · · Score: 5, Informative

    As one who has contributed significantly to the Wikipedia article on the War of 1812, I need to clarify this. It was the British forces, not Canadian militia, who landed in Maryland, defeated the DC militia at Bladensburg, burned the public buildings, and then moved to take Baltimore. At Baltimore the landing force was soundly defeated at North Point, and the ship force could not crack Ft. McHenry, so they withdrew.

    The Canadian militia performed very well, but they, like the American militia, faced problems when dealting with regular soldiers. General Winfield Scott and Jacob Brown led a regular US column into Ontario in 1814, mauling both Canadian and British forces at Chippewa. The British victory at Lundy's Lane in July 1814 was due more to Scott and Brown's wounding and the horrific casualty rate on both sides. The American forces actually took the Canadian and British guns, but were too weak to stay. They then mauled the Canadian militia at Fort Erie, Ontario, and moved back over the Niagara, guaranteeing a stalemate in the Northern campaign.

    The War of 1812 was one of those rare wars where both sides accomplished much of their war goals. The US did not annex Canada, but the gateway to the Southwest opened up, enabling us to move westward into Spanish/Mexican territory. The British began to give American positions more respect internationally, including a preference to negotiate agreements rather than fight. Canada became a nation, though Quebec and the Red River settlements were both problematic. There are reasons why both nations celebrate it as a victory, though technically it was a draw.
