You know virtually all the factories the slave labor force worked in they built themselves ordered under the SS.

V2's and ME 262's were also built in factorys inside mountains they slave force had to clear out.

All the aircracft and tanks and even the V2's and doudle bugs were all German design and owned.

Its good you want to learn more about history, but I'd try and find a more reliable source of information.. maybe history written by people who were there, instead of 20 year old conspiracy theorists.
