Manuscript Training Notes and mimeographed copies ofRobert A. Lewis' Bomb plan and Survival Maneuver, [Tinian Island, late July and early August 1945]
1. A 2 pp mimeographed copy of two plans drawn up by Lewis, 4to, the first a more expanded version of the bombing plan lot 289, the second the attack paths of all three planes as they approach Hiroshima, the photo and instrument planes hanging back as the Enola Gay goes straight in.
2. A 1 p single sheet of manuscript notes by Robert Lewis, 4to, in ink on a 4to graphed-ruled sheet, detailing velocities of the shock wave, and time taken to hit the plane as it headed home. Slightly yellowed. 3. 2 pp manuscript lecture notes on a small sheet of ruled paper, 8vo, titled Interrogation Spaatz, Giles, etc, the second page with notes on the radio frequencies being used, the barometric fuses that start the reaction, and the back-up fuses if it does not air burst.
Provenance: Robert A. Lewis, co-Pilot, Enola Gay, 6 August 1945; and then as a gift to Steven K. Lewis.
These notes represent fragments of Lewis's training in the build up to the Hiroshima Mission. The notes indicate that Lewis should have been more aware of what a strong blast wind and shock wave can do. The problem was, that most of the crew, apart from those that had seen tests in the lab, could not comprehend the concept that nature could create such energy by firing particle against particle, and the enormity of that energy remains beyond the comprehension of most people, even today.
