probie, P.V. Plusnin (can be Pavel/Paul or Petr) is confirmed aerodrome local. In the sense that it is unknown was he born in Smolensk, but air-controlled in Northern for many years. I wrote to private messages; and a reliable forumer (to me) (well, to all :o) speaks with a man who is long time acquaintance with the controller. As much as things can be known for sure in this imperfect world.
