Fact Checkers and Incendiary Balloons

John McPhee’s article on on fact checkers is fascinating. For one thing, I had no idea Japan launched paper incendiary balloons that were carried all the way to the US on the jet stream:

The Japanese called the balloons fusen bakudan. Thirty-three feet in diameter, they were made of paper and were equipped with incendiary devices or high explosives. In less than a year, nine thousand were launched from a beach on Honshu. They killed six people in Oregon, five of them children, and they started forest fires, and they landed from Alaska to Mexico and as far east as fifteen miles from the center of Detroit. Completing the original manuscrip of “The Curve of Binding Energy,” which was otherwise not about Hanford, I wrote half a dozen sentences on the balloon that shut down the reactor, and I turned the piece in. If Wheeler’s story was true, it would make it into print. If unverifiable, it would be deleted. I hoped it was true. The rest was up to Sara.
