Thanks WHBM for that Link -
Very interesting read and one of the best overviews of the whole B-50/B376/B377 family I have seen. Very informative.
Explains why the Ham Standards were preferred to the Curtiss props. The increased MTOW went right to payload if not to safety. Author calls it right, no one ever made a profit flying Stratocruisers. Notably however, in examining pictures, I notice that most of the B-50 had the Curtiss props though at least one had the square tips of a Ham Standrd.
Monograph contains what I believe are a few errors. The B-50 was not operated by the RAF to my knowledge and it was not named the Washington. However the B-29s operated by the RAF were called Washingtons. In US service the B-29 and B-50 were both the Superfortress. I also found the repetitious use of the phrase :New World Order" annoying.
