A retrospective on the first full day after a Ukraine International Airlines jet came down on departure from Tehran, with all 176 aboard killed.

What was understood on 9 January 2020, the day after Ukraine International Airlines Flight 752 went down in Iran? The Boeing 737-800 had crashed while taking off from Tehran Imam Khomeini International Airport on 8 January 2020, and all 176 people on board were killed.
The aircraft was operating a scheduled international service from Tehran to Kyiv. As reported at the time, the crash took place amid the 2019–20 Persian Gulf crisis, and the incident was under investigation.
Cause established later
On 9 January 2020 the cause of the crash was still being examined. It was established later that the aircraft had been shot down by the Islamic Revolutionary Guard Corps shortly after takeoff. That finding was not part of the picture on the covered date.
For Ukraine, the loss of an airliner from its flagship carrier, with no survivors among the 176 occupants, made 9 January 2020 a day of investigation and mourning.
