This appears to fall within RW's remit - but I don't presently have time to repurpose the WP article.
I don't think he fits the supposed topic of the article. The "lost cosmonaut" label refers to (alleged) anonymous people in secret flights who were never acknowledged. Komarov's death was known and publicized immediately - his urn was ceremonially interred in the walls of the Kremlin, FFS. That section also does not make clear which of the claims are controversial.--ZooGuard (talk) 17:47, 25 January 2017 (UTC)
