I have a very soft spot for planes from the Soviet Union/USSR/Russia. Lets say for all planes with a red star on it. There are of course tons of documentaries on the market, but this one is something really special. 18 episodes á ca. 1h (sic!) explain the very beginnings, the hard struggle during WWI and WWII, the cold war planes etc en detail. Every generation of the planes - from Gen. I to Gen. VI - is explained very well spoken, detailed and is based on facts.
Just a piece of art! May this be helpful to you and your modelling projects.
