I have read that even with the accute raw material shortages and rationing that went on during WWII, anything needed for the Manhattan project was was delivered on a silver platter. It was understood that if the United States failed to create a working atomic bomb before the Germans or the Japanese we would likely lose the war. Within the Manhattan project, nothing was given a higher priority than the special modifications that were needed to be made to standard B-29 bombers which would enable them to drop atomic weapons. For that reason these modifications were code named "Silverplate". Pictured here and preserved for history is the Enola Gay which dropped the first atomic bomb on Hiroshima Japan, the effects of which probably killed between 90,000 and 166,000 people while helping to end WWII and probably saving 1 million American lives.
