The S-200 (SA-5) is still around. It is a rather unique missile, although the SA-12 (S-300) and SA-10 (S-300) can partially replace it.
BTW, the report says that the missile exploded near the a/c, but did not achieve a direct hit. I wonder why. The Tu-154 is a large target flying at high altitude in a straight line. Even the SA-5 should have achieved a direct hit without any problems. Is it possible that someone recognized the mistake and was trying to fix it? Was the missile even aimed at the Tu-154?
Pacifism only works if EVERYBODY practices it
