Lewis wrote the original log on Augas he flew to and from Hiroshima, disguised as a letter to 'Mom and Dad' because as there was to be no official account of the top-secret mission, Bonhams said. Robert Lewis, American co-pilot of the B-29 bomber, made the copy in 1945 at the request of the then-science editor at The New York Times, and it includes a pencil sketch of the mushroom cloud, Bonhams auction house said. A copy of a deeply moving pilot's log, written during the top-secret Enola Gay mission that dropped the first atomic bomb on Japan, was auctioned in New York on Wednesday for $50,000.
