Lot of nonsense in this thread.

The German contributions to swept wing research:

1) German AVA/LFA/DVL wind-tunnel data gave proof in 1940
that Busemann’s 1935 supersonic swept-wing theory is also applicable
for subsonic compressibility effects.
2) The beginnings of area ruling can be traced back to Junkers’
patent in 1943.
3) Artificial stability (philosophy, Heinkel; theory, Fischel, 1940)
was first demonstrated by DVL’s rate gyro controlled yaw damper
(1944).
4) The existence of LFAVoelkenrode came as a complete surprise
to the Americans and British after WWII.
5) Only after von Karman and his scientific advisory team arrived
in Germany was the totality of the German aeronautical research and
design effort revealed.
6) German swept-wing wind-tunnel data dispelled U.S. doubts
regarding the validity of R. T. Jones’ theoretical work.
7) To preserve that scientific picture of LFA and AVA, every
hardware and technical data were boxed up and shipped off mainly
to Wright Field and to Bedford, United Kingdom.
Fairly extensive German wind-tunnel data were used for future
swept-wing designs in the United States, Russia, United Kingdom,
France, and Sweden.
