I know a little bit about Chome Dome and that there were some accidents/crashes, but hadn't ever heard about this accident in NM or the one near Savannah.
Some of those Chome Dome accidents were pretty dicey too. I think the Yuba City one had like 3 of 4 triggers armed or something if I remember the story correctly. Better to be lucky than good, I guess.
In the Goldsboro, NC incident, 4/5 safeties failed. They never found the second bomb.
