In the part of this episode talking about the MiG 21 on sale, as I remember, Jack was wondering wheather these planes have seen action back when they were on duty. And just recently I saw a clip on Youtube showing one of them still in action now, although not in its original role as fighter but as a bomber fighting the ISIS on the side of Syrian Air Forces. They've assembled it from different donor planes and armed with some makeshift bombs. It's a damn hardy plane

Anyway it would be so much more comforting to have all the old and new military planes perform only at airshows and not in actual combat..
Happy Chirstmas to everyone!
