It kind of makes you wonder what kind of world we would be living in right now if this had happened.
Would we have total nuclear disarmament right now?
Would the US have scapegoated the bombs on the russians leading to WW3?
Or would Godzilla be real?
Has there ever been an accidental nuclear explosion? It would be amazing there hadn't, especially considering the false alarms between the USSR and USA, and other near-misses like this.
Off the top of my head I can't think of any "accidental nukes", but there was something similar. The Castle Bravo nuclear test was like 3-4 times more powerful than they were anticipating and almost killed the whole crew associated with the test and made the atoll that it was tested on uninhabitable for a while, and also caused some japanese fishermen who were in a predicted "safe zone" to die from fallout.
