An associate of mine was a USAF Major who came into possession of a Soviet Belarussian MiG-21. He stashed it in a hangar in Germany and told absolutely no one outside his inner circle of war buddies about. The only person he ever showed if off to was a fairly high-up Russian who he mistakenly thought was "cool". Guess how long it was before the cockpit avionics were stolen, rendering it un-refurbishable? Sigh Never trust a Russian officer farther than you can throw them unless their name was Stanislav Petrov.
