Yak-15

[Almighty Blighty]

The germans had their ME 262 ready for combat in 1942, but because of engine problems they couldn't make it work properly. If the plane would have been flying by 1943, the world of jets would be alot more advanced now-a-days. every cloud and all, if the 262s were flying then many more people would have died. Still, Even if the russians did start designing their own jet fighter, they did not have an engine. The Yak 15 used a captured german design (the junkers jumo i think)
