Dear Thomas, i never liked much that "tube plus wings" philosophy, although i must say that the MiG-19 looks somehow attractive to me....
What always troubled me, when i was considering a Russian jet fighter, was why their electronics were so "primitive". When the F/A-18 was presented, it had 3 screens, whereas the best Russian cocpit was full of analog instruments. The answer must be that the Russians are thinking that numbers win technology, so the cheaper the aircraft, the bigger the fleet, the more chances to win a battle...
