From that article... '"I asked Siddiqi if he thought his transcript had been doctored. He said, "I'm 100 percent confident the transcripts are genuine," though there may be other recordings from other tracking locations.When I showed it to Bizony, he said, "An official Soviet transcript of anything, from the death of a cosmonaut to the birth of a healthy baby boy, isn't worth the paper it's written on. ... Given that we at least broadly trust Russayev's recollection of events, we are entitled to believe that Komarov, for all his discipline as a cosmonaut, would have been entitled to some spitting madness and frustration."'

Certainly that was my first thought when I read "Russian State Archive"
