All planes that ever flew look somewhat familiar to each other. They're all designed to do pretty much the same thing (to fly) and have some common elements (wings, control surfaces, crew accommodation etc).
md_wild_weasel Wrote:for example the XP-55 Ascender looks exaclty like the j7w1 http://en.wikipedia.org/wiki/Ky%C5%ABsh%C5%AB_J7W
The canard concept was not new, there were experiments long before WW2 with this configuration - even the 1903 Wright Flyer could be considered as a canard plane.
The XP-55 first flew in 1943, two years before the J7W, and well before anyone in the USA was even aware of what the Japanese or Germans were experimenting with during the war.
If there ever was a design in the USA that was influenced by the J7W and German tailless aircraft to any significant degree, it was the Vought F7U Cutlass:

This one too flew for the first time before the introduction of Me-163 into combat, before the Allies were able to examine it and learn from it or possibly even knew about its existence.
md_wild_weasel Wrote:The same for the YB_35 which looks the same as the Horton Ho 229 http://en.wikipedia.org/wiki/Northrop_YB-35. Can you c the patteren here?
YB-35 is descended from Northrop's own experiments with flying wings from 1930's (Jack Northrop is at least as much of a pioneer of this concept as the Horten bros were), Northrop had a flying wing prototype completed and flight-tested in 1940-41.
The pattern is to be expected - you have a number of engineers working on the same set of problems using the same basic scientific principles. They test different ideas, keep what they find useful and discard those more far-fetched or too far ahead of their time (flying wings were impractical until advanced computerized FBW systems came along late 1970-ish). It is similar to the evolution - sharks (fishes), some species of marine dinosaurs (reptiles) and dolphins and whales (mammals) all look strikingly similar yet are pretty much unrelared. Because they all live (or lived) in the same type of environment and had to catch similar prey to eat they all developed the same evolutionary characteristics.

Ask an american about the Parkard Merlin.. :wink: Also take for example a recent film " U571" which caused great offense over here in blighty.
my two cents worth on american "wonder" technology.
Yes, the Yanks (as well as the Russki) benefited a lot from the Axis research after the war, this is true, but that doesn't mean they did not invent any technology or that they just simply copied everything from the Germans. A lot of the concepts German advanced designs were based on have actually been common knowledge among the aeronautical engineers even before the war.
The British would've done the same (used captured Axis know-how) if they could afford it, but due to the damage caused by the war they coudn't and let the Americans lead the way. It was in their best interest to have someone develop technology for them faster than they would be able on their own, because of the Soviet threat as WW2 quickly turned into the Cold War.
And i'm sure if Germans would've won (God forbid!) they would test and learn from the Allied designs. They proved already they're not shy to do so, they used Russian know-how and ideas to design some of their mos famous tanks during WW2 (the Panther was directly influenced by the T-34).
It's all perfectly normal and to be expected...
