Transair Sweden in the context of "1961 Ndola Transair Sweden DC-6 crash"

On 18 September 1961, a DC-6 passenger aircraft of Transair Sweden operating for the United Nations (UN) crashed near Ndola, Northern Rhodesia (present-day Zambia). The crash resulted in the deaths of all people on board, including Dag Hammarskjöld, the second secretary-general of the United Nations, and 15 others. Hammarskjöld had been en route to ceasefire negotiations with Moïse Tshombe during the Congo Crisis. Three official inquiries failed to conclusively determine the cause. Some historians and military experts like Susan Williams have criticized the official inquiries, pointing to evidence of foul play that had been omitted from the inquiries.

Hammarskjöld's death caused a succession crisis at the UN when the Security Council was tasked with selecting his successor.
