Hiroshima
From Tardis Wiki, the free Doctor Who reference
Hiroshima was a city in Japan. It was hit by an atomic bomb in 1945, thus causing the Japanese to surrender, ending the Second World War. (COMIC: Sky Jacks)
In 1996, Chad Vandemeer used the GCI processor to create the Through the Eye of Eternity episode "Miss Hiroshima". It was subsequently lost in the archives through possible interference from the enemy. (PROSE: The Book of the War)
