The 509th Bomb Group, originally the 509th Composite Group, was the U.S. Army Air Forces unit that dropped the atomic bombs on Hiroshima and Nagasaki in 1945. Based at Roswell Army Air Field in New Mexico from November 1945, it was the unit whose officers announced the recovery of a "flying disc" in July 1947.[1][2]
Formation and the atomic missions

The group was activated on 17 December 1944 at Wendover Army Air Field, Utah, under Lieutenant Colonel Paul Tibbets, with a squadron of specially modified B-29 bombers and a transport squadron. It moved to North Field on Tinian in the Pacific in May 1945. On 6 August 1945 the B-29 Enola Gay, flown by Tibbets, dropped the "Little Boy" bomb on Hiroshima, and on 9 August Bockscar, commanded by Major Charles Sweeney, dropped the "Fat Man" bomb on Nagasaki.[1]
Roswell

The group returned to the United States and was stationed at Roswell Army Air Field from 6 November 1945. Colonel William Blanchard replaced Tibbets as commander on 22 January 1946. On 21 March 1946 it became one of the original groups of the new Strategic Air Command, and on 10 July 1946 it was redesignated the 509th Bombardment Group, Very Heavy.[1]
In July 1947, after rancher Mac Brazel reported debris near Corona, the group's intelligence officer, Major Jesse Marcel, collected it and the base announced the recovery of a "flying disc". The group's own history for July 1947 recorded that the public information office was kept busy answering enquiries about the disc, which turned out to be a radar-tracking balloon. In 1995 the U.S. General Accounting Office found that this history was one of only two surviving 1947 government records about the event.[2][3]
Later history
The group converted to B-50 bombers in 1950 and was inactivated on 16 June 1952; its lineage continues in the 509th Operations Group, activated in 1993.[1]
