Alrighty Anons, spent a considerable amount of time following those other links. One in particular was a huge trove of information:
https:// www.newsru.com/russia/12feb2018/an.html#44
It lists a bio of almost everyone on the plane. Another of the linked sites had named photos, thank God.
In looking at the number pattern and bios, Sergey Panchenko and Ilya Alexandrov stand out the most to me. There are some other interesting ones too if you read through the bios.
Panchenko is the only one so far who MAY have had a Rosatom / Dossier connection, but it seems weak.
Alexandrov is Spetznaz, pretty much says it all. Could have been involved in anything.
Anyway I pulled 8 names out of the list who seem to warrant deeper digging. Need help, Anons!
