Central Armed Forces Museum in Moscow - nice collection of tanks, SAM's, Ballistic Missiles and aircrafts - but miserable to photograph them without other things in the way. Hind-A with side-by-side Cockpit
preserved at the "Tan Son Nhut Air Force Museum" in HCMC/Saigon, which has a small number of Vietnamese AF aircraft on display that are not so good placed and unfortunately in a very bad condition...
