William Laurence" (after their return to base). Halfway through I ran out of ink," and explains that the occasional pencil corrections "were made by Mr. Rhodes, The Making of the Atomic Bomb, p.706.) Lewis notes that "a great deal of the notes were written in almost complete darkness. He asked me to keep some notes of the Mission." (According to another account, Laurence was bumped from the mission entirely, see R. He had been ordered to be aboard, but arrived in Tinian too late. On the inside cover, two days after the mission, Lewis explains the creation of this unique historic record: "This log was a last minute request of William L. Tibbetts carried cyanide capsules to distribute to each man to prevent their revealing, under interrogation, anything about the top-secret weapon or their mission. If they experienced engine failure or were shot down, Col. The crew and the two special technicians who accompanied them on this flight had been advised, though, of the possibility that the airplane itself might be blown apart when the bomb detonated. In fact, not even the team of scientists who had designed, built and installed the bomb knew whether the device would explode as planned, or could calculate its destructive potential. Tibbetts and the radio operator had detailed knowledge of the nature and potential destructive power of the mysterious weapon they carried. The youthful ten-man crew had trained for almost a year for this "very special mission" that "might end the war," but only Col. In the aircraft's bomb-bay rested a single 9,000-pound bomb unlike any other ever carried into combat. Paul Tibbetts, the Commanding Officer of the 509th Composite Group, a unit specially formed and trained in the highest security for this special mission. Piloting the four-engine aircraft was Col. airbase at Tinian Island in the Marianas at 2:45 a.m. The B-29 chosen for the momentous mission, with the name Enola Gay in large letters on its nose, took off in pre-dawn darkness from the U.S. It constitutes-with the sole exception of the navigator's log, which numerically recorded the aircraft's course, airspeed, latitude and longitude-THE ONLY IN-FLIGHT, FIRST-HAND ACCOUNT OF THE BOMBING OF HIROSHIMA. Lewis's log is a unique first-hand record of the violent birth of the atomic age. For most of us, though, the atomic age begins with a single cataclysmic event: the detonation of the first atomic bomb over the Japanese city of Hiroshima, at 8:16 a.m., August 6, 1945. The Manhattan Project was initiated in response to that letter, and its massive, secret research and production efforts culminated in the fall of 1945 in the operational deployment of "Little Boy," the world's first atomic weapon. Roosevelt that "extremely powerful bombs of a new type" might be created from the physicists' new understanding of atomic theory and the application of his own famous equation of equivalence E=mc 2. The atomic age, some would say, began with crucial early experiments by scientists including Niels Bohr, Lise Meitner, Enrico Fermi and Robert Teller in the late 1930s, or with Albert Einstein's and Leo Szilard's famous letter of Aug(see lot 161) warning President Franklin D.
