Didn't they modify one of the Consolidated beauties to operate on nuclear power?
I sort of remember that.
Don't know if they ever did but I remember reading about it being discussed in Dad's Popular Mechanics magazine.
They never installed a reactor to power the aircraft, but they did have a functioning research reactor in the aircraft.
It got pretty hot.
