Itavia 870 comes to mind: In the 80ies, a fighter jet was being smuggled to Gaddafi by hiding under a civilian aircraft, and the speculation is that France shot the convoy, killing 81. https://en.wikipedia.org/wiki/Itavia_Flight_870
Russia/USSR does seem overrepresented here.
Do you have any sources for that? The article you link does not seem to mention that theory.
Sure the article mention a theory that Gaddafi was in a fighter jet, and the civilian plane was a collateral damage from a dogfight, but given the lack of information in the public space, both theories still have a lot of common points.
Some view the denying of emergency landing clearance as an effort to destroy/obscure evidence: https://x.com/DailyTurkic/status/1872008574878298418
