LENA. Kiev.
In 2001 two missiles were launched at a drone. One of them shot down the drone, another had to self-destruct, but didn't.
Here you are not quite right. Missiles do not self-destruct immediately upon missing the target. Usually, and S-200 SAM is the case, this happens when voltage of the internal power supply drops below a certain value.
If we trust Ukrainian documents, after the miss, the target illumination was turned off. The SAM flight was uncontrollable. It can be a wild coincidence that the SAM path came near the Siberia plane at the time when the self-destruction system initiated the warhead. The time from the missile technical description matches the flight time precisely (within tolerance).
