Launching from the Japanese sub I-25, Nobuo Fujita piloted his light aircraft over the state of Oregon and firebombed Mount Emily, alighting a state forest. The president immediately called for a news blackout for the sake of morale. No long-term damage was done, and Fujita eventually went home to train navy pilots for the rest of the war.
