If you haven't already started doing so, read that dissertation on long-range fighter escort that CougarGA7 linked to a few posts earlier. It is a gold mine of information. The first several pages are hard to read due to bad photocopy but they aren't particularly interesting either. The rest of the document is very readable.
As with any new technology, there were a lot of dead ends and necessary refinement before it becomes effective and readily available.
Agreed. The Germans had to proceed forward with development of the Me-262 and other jet aircraft. One wonders though if they might have been better in the short term to put a little more effort into an interesting design using more proven technologies like the Dornier Do 335?
Comparatively, the Do 335 would have been an easier design to implement on a large scale and it was supposed to be an extremely agile fighter. One of the reasons you don’t see more of these making it into combat was due to the Do 335 having all its eggs in one basket.
The tooling for the manufacture of this aircraft was all at the Dornier plant at Manzel. In March of 1944 this plant was completely destroyed in an Allied bombing run and production of the Do 335 was halted entirely until they could get a new facility online at Oberpfaffenhoffen. As far as I know by the end of the war a little over a year later there still was not a deployed Do 335 unit.
