A [question][1] on Aviation.StackExchange asked why the German aircraft industry is smaller than other countries in Europe. I know that the Allies did not want German rearmament after the war and had restrictions on industries that could manufacture war materials. In addition, since many of the rocket engineers went to the US or the USSR, I suspect that many of the aircraft designers did as well.

What were the restrictions on Germany, (and Austria and Italy) after the war and when were they lifted? 

East Germany was controlled by the USSR and I imagine that they also restricted aircraft manufacturing since most of the East Bloc used Russian military equipment. Did they have the same restrictions on their military?
