Interestingly (at least to me, and continuing to be off-topic) the
business about propaganda seems to be very important in this time frame.

  - As the Brits began to employ decent airborne radar, they 'sponsored'
a propaganda campaign that the air effectiveness was due to the RAF
pilots eating lots of carrots to improve their night vision.

  - The business about German vs Brit propaganda in this time frame was
partially overshadowed by the problem of concern about British communism
(and fascism), which was much aided by the blitz which exaggerated class
conflicts.
