In the early-morning darkness of that historic day 75 years ago, Colonel Tibbets and his 11-man crew boarded the plane and began their preflight preparations. It was all leading to one day that would help end years of bloodshed and change the world forever. Even years before that, development of this revolutionary cargo began in secrecy under the direction of a physicist and an Army general in the mountains of Northern New Mexico. and his crew had practiced dropping dummy concrete bombs on targets in Wendover, Utah. And months before that, pilot Paul Tibbets Jr. Preparations on the tiny Pacific island-about 1,500 miles southeast of the plane’s intended target in Japan-had begun months before on April 3. Hours before the sun would rise over Tinian island on the morning of August 6, 1945, a B-29 airplane was positioned above a specially built bomb-loading pit, as crews readied the aircraft with cargo unlike anything the world had ever known. and others explain, delivering a 10,000-pound bomb to southern Japan was a years-long endeavor that required patience, practice, and precision. We were all dumbfounded.On August 6, 1945, the crew of the Enola Gay dropped an atomic bomb designed at Los Alamos on the Japanese city of Hiroshima. "We just looked at each other we didn't talk. "Things were very, very quiet," Gackenbach says. The plane circled twice around the mushroom cloud and then turned to head home. He got out of his seat, quickly picked up his camera and took two photographs out the navigator's side window. The first thing Gackenbach saw was a blinding light and then the start of a mushroom cloud. Then, the radio went dead: that was the signal from the Enola Gay that the bomb had been released. "We were not told anything about the cloud, just don't go through it."Īs they made their final approach to Hiroshima, they were flying 30,000 feet over the city. "We were told that once the explosion occurred, we should not look directly at it, that we should not go through the cloud," he says. Gackenbach was part of the 10-man crew that flew on the Necessary Evil. The atomic bomb explosion photographed from 30,000 feet over Hiroshima on Aug. They had different engines, fewer guns and a larger bomb bay. Their planes were reconfigured B-29 Superfortress bombers. The 509th Composite Group, lead by Tibbets, spent months training in Wendover, Utah, before being shipped off to an American air base on the Pacific island of Tinian. Tibbets said it would be dangerous but if they were successful, it could end the war. Paul Tibbets, who was recruiting officers for a special mission. After completing his training, he was approached by Col. Gackenbach enlisted in the Army Aviation Cadet Program in 1943. Today, the 95-year-old is the only surviving crew member of those three planes. Army Air Corps and a navigator on the mission. Russell Gackenbach was a second lieutenant in the U.S. There were three strike planes that flew over Hiroshima that day: the Enola Gay, which carried the bomb, and two observation planes, the Great Artiste and the Necessary Evil. It was the first time a nuclear weapon had been used in warfare. 6, 1945, the United States dropped an atomic bomb on the Japanese city of Hiroshima. Russell Gackenbach was the navigator aboard the Necessary Evil.
