America was bombed 1,000 times during World War II

I had no idea America was bombed 1,000 times during World War II. "School children in Japan were asked to make gigantic balloons, thirty-three feet in diameter. The first prototypes were made out of paper, but later ones were made from silk. The balloons, when filled with hydrogen gas, were buoyant enough to carry a thirty-three pound bomb, as well as a few incendiary bombs and thirty-six sandbags. When released they would shoot up to 35,000 feet. They'd leak gas, slowly dropping, until a barometer caused one of the sand bags to drop off into the sea, at which point they'd go up to 35,000 feet again. The balloons could travel on air currents at up to 120 miles per hour, and so, when the last sandbag fell, they descended onto North America. For navigatorless objects, drifting on the wind, a surprising amount of them made it over the sea.

Out of the nine thousand launched, about one thousand reached land, while the rest exploded in the sky or dropped into the ocean. The bombs went off as far east as Kansas and Texas. Some drifted down to Mexico, and some up to Canada. Although the bombs caused a few fires, American officials asked people not to talk widely about them. The bombs didn't cause any actual casualties until 1945. Six people, five of them children, were killed at a church picnic, when they saw a deflated balloon and touched the bomb, not knowing what it was."
