Yes Oli and as you know it is what is not said that is the important part, major global companies like BAE or Dasault do not waste investments like this. I saw the Demon, inside and out, and had consersations with some of the graduates and development engineers as part of an exhibition showcasing new technologies and the spin-offs last year.

The blown surfaces use a seperate Wren gas gen and thrust is from an AMT Titan so they are even indirectly investing money in our own hobby.
