At 6 AM in the Pacific off the coast of Oregon, Warrant Officer Nobuo Fujita takes off in his “Glen” floatplane from Japanese submarine I-25, flies inland and drops 2 incendiary bombs into the forest on Wheeler Ridge, Mount Emily. The intention is to start fires but rain-soaked brush renders the bombs ineffective. 1 small fire is put out by the US Forest Service. This is the only bombing of mainland USA in WWII. Nobuo Fujita will return to Oregon several times between 1962 and 1995 as a goodwill ambassador. Some of Fujita’s ashes are now buried at the bomb site.
