No harm done, and I certainly understand a thing or two about failing to communicate myself in a way that is parse-able by others and retains my intent. I understand that all too well.

As for broken arrows: “A Broken Arrow is defined as an unexpected event involving nuclear weapons that result in the accidental launching, firing, detonating, theft, or loss of the weapon.”

The nuclear powers all have way too many embarrassingly stupid ones on record, given that you’d expect nuclear weapons to be the literal most important thing with the literal most stringent procedures for handling.

There was one in NM in the 50s with some limited contamination exposed in the local area, and I thought that’s what you were referring to.

Wikipedia has a neat list of both broken arrows (military accidents) and civilian ones, involving nuclear technology.
