This is slightly off target but in looking at those French designs, did not the last one basically look like a Yak? I've seen design specs for a 1960's era jet that Mirage did not build. It was a single engine, high, swing-wing super sonice attack plane. It looks almost identical to the later Mig-23/27 bird. There is almost no chance the Russians/Soviets designed the Mig-23/27 and it just accidentally looks like the French plane. Did the French collaborate with the Russians/Soviets as early as the 1940's?
