In late 1944 the now Lieutenant General B Affleck (later Vice Admiral) put a proposal before the Joint Chiefs in Washington. This proposal was to equip high attitude balloons with incendiary bombs, and to launch them in the Mid-Pacific so they would float toward Japan. These balloons were designed to release their bombs when they were over Mid-Japan, which was known to be heavy forested. It was hoped that the incendiary bombs would cause large forest fires, putting strain on the Japanese economy. The Balloons were duly built, and taken to the mid-Pacific were they were launched from a Aircraft Carrier. But it was found that these balloons traveled the wrong way when launched, because the prevailing winds at this latitude West to East.
Here is a picture of the launching of one of the balloons I managed to track-down:
