In addition to the OP, I think that this story is something of a critique on the German attitude in WWII, and a warning to not repeat the same mistakes.
I mean, how much time/money/effort did they put into things like the ME-262, Maus, etc. when their soldiers were freezing on the battlefield in summer uniforms? How many of their machines that they did manage to field had frequent mechanical issues due to overengineered engines/transmissions?
The list goes on and on.
And do note that to a certain (large) extent, we’ve adopted their philosophy toward weapon systems. And how many wars have we won lately with our wunderwaffen?
The ME-262 prototype was ready in 1937. Hitler refused to spend more money on it until 1944. So, in 1944 there were still no viable jet engines for it.
