Shooting Down the Nuclear Plane, by W. Henry Lambright, (Inter-University Case Program #104, Bobbs-Merrill Co., 1964), is an interesting and nicely-documented history of an idea whose firm grasp on reality night not be terribly firm. Of course it would be possible to prodce such a thing (at about this same time in 1961 appeared a cover for Popular Mechanics for an atomic-powered car from which two cowboys went a-hunting) if there was the collective will to do so, and there almost was. Let's just say then that the atomic-poweredness of our domestic defense was limited to aircraft carriers and submarines, and the atomic-powererd aircraft were left to science fiction .
In general though it was at this time, from about 1946 thorugh the late 1950s', that people were thinking of refitting standard power systems with atomic energy.
Here are a few ideas for alternative approaches to flight, provided by the happy folks known as Atomic Energy:
