By pure chance, I once found an old family history in my fathers apartment typed up by my grandmother. Apparently, together with those papers, where some old notes from her job. She used to be the secretary to some scientist at swedens first nuclear research program around 1954. In those notes, I read speculations about nuclear powered ships and I think they mentioned aircraft, but ships for sure. Here is an image of the "cave" where they had their research reactor: https://www.kth.se/polopoly_fs/1.1300045.1701333137!/image/Reaktorhallen419.jpg about 25 meter under the city campus of the royal institute of technology. --8323328-386909428-1733950600=:16136--
