If you look at the pictures from "gas chambers", you can clear see that they had normal wooden doors. The soldiers outside would surely be killed. Those from the pictures could be barracks, anything, but gas chambers. And besides, hydrogen cyanide poisons by contact, so how would the soldier carry away the bodies after they were killed?

There are no schematics of gas chambers whatsoever. In the holocaust museums, there are only "artistic" representations of gas chambers. When some researcher went to the museum and asked for a technical drawing from the director, he refused whatsoever and sent him away.

That's enough proof for me that they were impossible.
