Wikipedia:Articles for deletion/Voronezh UFO incident
Article has three big-name media sources; that passes WP:GNG.  The only potential weak point I can see by that standard is that U.S. media sources might be argued not to be "independent" of Tass, being cold war and media rivals, but if you were to maintain that it would change how many articles about the Soviet Union are judged for any purpose.  The fact it's a mass delusion with no real basis is irrelevant - for example, we have articles about Bitcoin and several satanic ritual abuse witch-trials.  Once people deploy real resources based on a delusion it is no longer nonexistent.  Any invocation of  is wrong because our mainstream sources are giving the overall "normal" point of view of commentators about the subject.  You don't say a subject itself is "fringe" based on your opinion of it
