10 Mar 1945

United States
  • A Japanese Fu-Go balloon came down across electrical lines in Toppenish, Washington causing a power outage. Although not widely known for another ten years, the outage shut down the reactor at the Hanford, Washington facility of the Manhattan Project. Back-up systems quickly restored power but it would take another three days for the reactors to reach full capacity again. A burned balloon envelope, shroud lines, and ballast dropping equipment were recovered from the downed balloon. At almost the same time, another complete Fu-Go balloon bomb grounded near Cold Creek, Washington, very near the Hanford site. ww2dbase [Operation Trinity and Manhattan Project | Japanese Attacks on the Continental United States | Fu-Go | Toppenish, Washington | DS]
