I have a question. If a United Nations secretary-general dies in a plane crash, and the official investigations cannot agree whether the plane crashed by accident, was attacked, or was sabotaged, at what point does it stop being an accident and start being a historical argument with wings?
This happened in nineteen sixty-one. The plane went down near Ndola, in what was then Northern Rhodesia. Sixteen people were aboard. Nobody survived. And for sixty-five years, people have asked whether Dag Hammarskjöld was killed because he was finally getting somewhere in the Congo.
I do not know if that is true.
I do know the first explanation was pilot error, the later explanation was maybe an attack, and the newest United Nations review says an external attack or threat remains plausible. Which is an extremely official way of saying: we still do not have a clean answer.
So today we are doing the thing I always tell myself I will not do. We are opening an old file, following the evidence, and trying very hard not to turn every missing page into a confession.
That last part is difficult. I have a history here. I once spent six months investigating a municipal corruption story that turned out to be an accounting error. A number was in the wrong column. I built a theory around it. Six months. I could have learned a language. Instead, I discovered arithmetic.
So: what happened to Dag Hammarskjöld? And did the evidence become stronger over time—or did the story simply get better at surviving?
In this episode:
• A peace mission ends in the dark
• The official explanation meets the witnesses
• The attack theory gets a second life
• The newest report still refuses to close the file
