Just as I have no interest in any Russian airplane, I have Zero interest in the Zero. Nothing to do with Aeroplane Heaven, just my quirky inherited prejudice against WWII Japanese. My Dad fought the Japanese on Iwo Jima. He was also slated to invade Japan before Hiroshima and Nagasaki. He told me the Allies expected over a million casualties, if they had to invade the Japanese mainland. That was part of the reasoning in the decision to drop the atomic bombs. As horrific as they were, the casualties in Hiroshima and Nagasaki were less than the expected death toll from an invasion of Japan. At least, that is what my Dad was told and believed.
For a week every month I went into an underground bunker to sit on Nuclear Alert. I did this for three years. I studied the routes into Russia we would have taken, and viewed some of the first satellite images of target sites. If the klaxon would have sounded and the code said go, we would have gone. If we made it to the targets we would have rained nuclear hell on those poor people. I know we would have done so. There would have been no home to return to. Everything we would have known and had, including family would be gone. Besides, our training would have taken over... or perhaps vengeance. I am very thankful it never came to that.
So, I do not own a Soviet aircraft in DCS or MSFS, except for the free ones, which I have never flown.
Interestingly enough, however, I have sat in the cockpits of both a Mig-21 and a Mig-23. This was at Nellis, AFB, where they have/had a bevy of Soviet era aircraft. This was so US and US Allied pilots could learn more about the aircraft. They also had a huge (about 400 sq meters) three dimensional map of the Fulda Gap in Germany. The Fulda Gap are two corridors of lowlands through which Soviet tanks were expected to invade Europe, if there had been a WWIII. Nukes were planned for it too.
