Author Joel Dobson talks about his book “The Goldsboro Broken Arrow,” on the 1961 crash of a B-52 bomber in rural North Carolina. The plane carried two nuclear bombs, each 250 times more powerful than the one dropped on Hiroshima. One bomb was later recovered; the other is still partly in the ground. Mr. Dobson explains the Cold War political environment of the time, the events of that day, and how we barely avoided nuclear disaster. The Wayne County Museum in Goldsboro, North Carolina, hosted this event.
