The fact that the bombs dropped has been common knowledge. The fact that one of the bombs was one step away from wiping that part of the world off the
face of the Earth, has only just been released.
That's been known for some time, though somewhat inaccurately.
Here's an old wiki that says all but one of 6 safety mechanisms triggered:
The latest revelation is the same that only one safety device remained, but that was out of a total of four, not six, and the latest wiki article
reflects that change.
The OP story even mentions this discrepancy between 4 and 6 total:
In it, he comments on and corrects Lapp's narrative of the accident, including listing that three out of the four fail safe mechanisms failed,
not five out of six as originally thought by Lapp.
In either version, only one safety mechanism remained, so that fact has not changed and it's not really a major revelation from that perspective.
