I honestly couldn't tell you.It seems KXK (Komsomolsk na Amur) gets no Civilian traffic! Does this mean that the Airport is closed for Security reasons? Or that Komsomulsk is operating as a defacto (or declared) closed city?
I can imagine with the Sukhoi Aircraft Manufacturing being based in the City security concerns would be paramount. But the facility is located at a different Airport (UHKD) and there seems to be no alternative Airports for Civilian Traffic nearby (correct me if I am wrong).
It must be virtually unprecedented for such a large and isolated Russian City, over 260 000 people according to Wikopedia, to have no regular Air Service. I would have thought the Aircraft Manufacturing Plant alone would necessitate many Business related flights between MOW and KXK. Not to mention the local population needing to access the outside world for Education, Medical Trips and Holidays. KHV is about a 5 hour drive away.
Can anyone explain this gap in the network?
