Nuclear rocket silos aren’t everyone’s idea of fun, probably, but they turn me on. So much so that I talked about exploring one of them on Radio 4’s From Our Own Correspondent. About eleven and a half minutes in, if you’re interested. https://www.bbc.co.uk/sounds/play/m000zv39. In order to milk the experience maximally, I also wrote about it for the London Review of Books: https://www.lrb.co.uk/blog/2021/october/out-of-the-silo.
