I thought I read somewhere once that jet fuel was not in such short supply. All the prop-driven aircraft of the era used gasoline, as did the German trucks and tanks. There was less demand for the heavier fuels and as such they remained more available.
Not exactly. The jet fuel they used was a mix of gasoline and diesel, so even just that limited the supply of either for other uses. They were also very limited in production capacity. They could make about 1000 barrels a day in 1944 at the best capacity -- which meant about half a percent of the total synthetic fuel production -- and this declined over the year as the RAF and USAF were mercilessly bombing refineries. We're talking two orders of magnitude down by February 1945.
So no, they didn't have ample supplies of it.
But poor metallurgy in the jet engines limited flight training time anyway.
Well... sorta, and sorta not. It's a mix of actual limitations in available materials (you're not going to make the turbines from tungsten when you need it for AP ammo AND industrial tools, and you don't have enough for either), and bad decisions by Speer.
See, Speer was only obsessed with increasing production numbers to show to Hitler.
This included a lot of counter-productive decisions like nearly stopping production of spare parts, since those didn't show up in the numbers of complete tanks. Sure, half those tanks would be sitting broken instead of fighting, but he could brag to Hitler that he increased tank production numbers.
Other decisions were about using slave labour even where it was utterly unqualified. This resulted in stuff like the Type XXI electroboot subs not having a single one fit for duty after they had been put together that way.
And in the case of both jet engines AND the much maligned final drive on late German tanks, it was his decisions to go with a cheaper version even if it severely limited its life expectancy. I mean, at least for the jet engine he was saving some materials, but for those final drives, simply he could produce them in a shorter time per unit by going with the most simplified design that could get the job done. And, again, see that crucial goal: showing Hitler some great production numbers.
