06/18/2007. Remarks by Weldon Stevens: "The best looking B-36 is the one modified for nuclear experiments (originally XB-36H). Unless someone got a picture of it taking off or landing, it couldn't be photographed because it was kept in a secluded area with guards. It had a different nose and the crew comparment had thick, heavy lead lining. There was a nuclear reactor in the rear. They tested the reactor, but the plane never flew under nuclear power. Even though I had a top secret clearance and was often in the nuclear area, I could not go near the plane. Any inventory that I had to do of test instrumentation had to be done by someone else. It was scrapped at Ft. Worth, Texas, USA, 1958."
