In Iran, the Civil Aviation Organization in its report explained why Iranian air defense shot down the Ukrainian UIA Boeing 737.
The reason was an error in the settings of the air defense system.
“One of Tehran’s air defense systems has been relocated. This led to a change in its geographical position and direction. After the migration, the reconfiguration was not performed”, – the report says.
So, the system perceived the plane as an object that moved towards Tehran, while it flew out of the capital.
