If I'm not mistaken, the FW-190C prototype (V13) with the DB 603A was flying in mid-1942 and the D-0 with the
Jumo 213A was flying in October, 1942. 1942!
A precious year goes by....
On May 25th, 1943, Galland issues this memo and several days later Milch orders the Me-262 into series production.
BUT, Milch and everyone else ignores the more immediate issue of canceling the Me-209 in favor of the Jumo/DB powered 190's.
Over a freakin' year goes by and finally the D-9 is ordered into series production...
But by then it's too late, way too late... I'm utterly amazed by this sequence of events.
