The Morning star. In the war the question was when to make the jump in technology and where. The Germans went all the way to the 262, but they were too complex,too many materials that were hard to come by,and politics make production hard. The Americans didn't go for jets ,they went with the P-51,which destroyed the Luftwaffe and were able to fly Bomber coverage round trip. Then the pendulum swung the other way. By Korea the time of piston driven aircraft was over. The Soviet MiG 5 ruled the skies til the American made copies of it. Timing,is everything.
