The Enola Gay, the B-29 bomber that dropped the atomic bomb on Hiroshima on August 6, 1945, was not destroyed by the bomb. It was the city of Hiroshima that was destroyed, with an estimated 140,000 people killed instantly and many more dying later from injuries and radiation sickness.
The Enola Gay returned safely to its base in Tinian Island after the mission. Tibbets and Ferebee continued to serve in the military and both retired as generals. Tibbets died in 2007 at the age of 92, and Ferebee died in 2000 at the age of 81.
