Received my copy from Amazon today, a superb book with interesting  text and plenty of pin sharp photographs. I was pleased that the P1154 was given very detailed  coverage as it is a particular favourite of mine.
I hope Mr Buttler is considering a companion volume on the Hawk.

The Popp article is downloadable in English from the Wiley site - paid access or via OpenAthens etc.

It's very interesting, and confirms that German scientists had no idea how to make a bomb, and hadn't even thought about it much except in the broadest terms. Previous analysis by historians was hindered by them not understanding the technology enough to judge the source documents correctly and conclusions were biased by the author's own opinions.

When I saw the title, my first reaction was "because they didn't know how and couldn't afford it"  Bingo.  Another thing to consider-Just look at the size and scope of the Manhattan project, both in Washington and Tennessee.  And this allowed them to crank out about one bomb per month.   I don't know of any book on the history of the Axis war industry, but it would be interesting.

Basically, you can click the specific airplane you want to fly (even obscure ones) and you'll find info on which (hardcore) flight sims have that plane and what the best one is (in my opinion of course) - there's screenshots and videos included as well! The index list is on the homepage http://www.bestflightsims.com

Here's an example listing is for the F-16 https://bestflightsims.com/best-f-16-flight-simulator-game/

This is very much a work in progress, but keep checking back and you'll find lots of updates! I hope you find it useful and feel free to share with any flight sim enthusiasts you know!

When I saw Martin model 216-1 flying wing drawing, I had following impression.
(1)Each wing four engine propeller thrust line direction are different. Outer two engine propeller thrust line are almost horizontal, but inner two engine propeller thrust line directed upward.
(2)Engin cooling is by skin cooler? I see many steam cooling channel at wing cross section upper surface.
(3)Engine side round device is turbo supercharger?
(4)Engine intake air outlet nozzle is located wing under surface.
(5)Engine air intake size is very large. Engine is liquid cooling type, but located in air flow. Why?     

On (1), could this have been an attempt to deal with CG bombload issues? It would seem that altering the power for the inner, upward-inclined engines could add extra pitch control.
HmHmHm.......Thanks a lot. :D I confirm that engine is liquid cooling turbocharged R-7755 by Jared-san's book.
