    Critique of 1945 German aircraft designs - where were the mistakes?

    I heard rumour that TsAGI analysis found that the Ta-183 Design II would have shed its tail (although the IAe 33 Pulqui II seems to have eventually managed to make a somewhat similar t-tail work). What other issues did late war WWII designs have? Ju EF 128 intakes might have had a lot of duct...

    Does anyone have a copy of "Wireless for the Warrior" by Meulstee?

    I'm putting together an article on the Wireless Set No. 10, which deserves to be MUCH better known - it was the first TDM and PCM comms system in the world.
