Sure a few have been published before? "These previously unseen pictures reveal the preparations in the hours leading up to the US nuclear attacks on Hiroshima and Nagasaki. The atomic bombings of the two cities in Japan were conducted by the US during the final stages of World War Two in August 1945. To this day, the bombings remain history's only acts of nuclear warfare. The 509th Composite Group of the U.S. Army Air Forces was equipped with a Silverplate Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands, to the south of Japan. A uranium gun-type atomic bomb, code-named 'Little Boy', was dropped on Hiroshima on August 6, 1945, followed by a plutonium implosion-type bomb, called 'Fat Man' on the city of Nagasaki on August 9. Within the first two to four months of the bombings, the effects killed 90,000–166,000 people in Hiroshima and 60,000–80,000 in Nagasaki. Almost half of the deaths in each city occurred on the first day." http://www.dailymail.co.uk/news/article-2786215/Inside-America-s-atomic-bomb-programme-Never-seen-photos-reveal-preparations-attacks-Hiroshima-Nagasaki.html#ixzz3FhfGDeI4
