Update: What In The World Happened Here? LVIII (58):Link.
Yesterday one of my best friends (who I see around once a year) dropped by for a visit. Knowing that he was originally from Oak Ridge, I asked him if his father was involved with any of the reactors. Yup, he said, the Molten Salt experiment. But because most stuff was secret, he wasn't told any details. Dave did tell me that his dad was involved with the Tower Shielding Reactor, which investigated the feasibility of nuclear-powered aircraft. And that Alvin Weinberg was a family friend.
