Off topic, aviation content, but reflective of the Russian approach to weapons development. The story of the 'development' of the first Russian jet, the MIG-9, with some interesting referrals to the barriers to success and the way the Russians just sort of pushed ahead, ignoring problems and not testing. We still see the same things today in Ukraine.... Fascinating how things don't change.
