In the decades since two modified B-29s dropped atomic bombs over Hiroshima and Nagasaki, Japan, bringing World War II to a close, there have been many ideas about how the power of the atom might be harnessed for other uses, including space exploration and aircraft propulsion.

On this episode, Aviation Week editors comb through our archives to discuss the legacy of the atomic bomb missions and the evolution of nuclear power in aerospace through to the present day—and beyond. “We hold in trust a power that is capable of unraveling the very fabric of our civilian…We have proved the destructive use, while the constructive applications are still in the realm of speculation.”-AW&ST, Sept. 1945
