This picture has never ceased to amaze me. Taken just a little over 1.6 miles away from the bomb’s blast point, it is the only known photo taken from the ground just after detonation. The blast itself destroyed everything within a 1.5 mile radius. Even though other pictures were taken close to the blast point, it’s practically a miracle that someone was able to take a picture of it just outside that radius of destruction.
