Seems like you can get a great spotting trip to North Korea and fly in and photograph classic Russian birds as much as you like. Check out the tours for 2015 here. Tempting but difficult to marry up with my scruples! Anyway Air Koryo is an interesting airline.
Air Koryo is surprisingly well represented in 1:400 scale models with there now being 10 releases including 5 IL-76s, 2 IL-18s, 2 TU-154s and an IL-62.
