I can’t seem to find any sources about any of these specific crashes. There just isn’t enough information Erfson ( talk) 05:31, 5 December 2018 (UTC) reply

@ Erfson: There are not many sources available in English - you have to search in Russian. Very little information about the crashes is available in English, so at the task force was established to transfer the Russian-language information to enwiki.-- PlanespotterA320 ( talk) 16:31, 5 December 2018 (UTC) reply

Viewing the Russian-language article (linked on Wikidata) helps with starting to draft an article. And there are sources at the bottom of the page from the Russian wiki articles.-- PlanespotterA320 ( talk) 16:33, 5 December 2018 (UTC) reply
