B-29 Superfortress Enola Gay, Udvar-Hazy Center

On 6 August 1945 this B-29, flown by Col. Paul Tibbets, dropped the first atomic bomb used in war, on Hiroshima. It is the most historically weighty aircraft in this gallery, and seeing it in person makes the scale of the B-29 obvious: the bare aluminum fuselage dwarfs the fighters parked beneath its wings. The fully restored bomber has been on display at the Smithsonian's Steven F. Udvar-Hazy Center in Chantilly, Virginia, since the center opened in December 2003.
