1. I do NOT own these pictures.
2. YOU (probably) do NOT own these pictures.

Apparently he just allows uploads without regard to ownership and protects himself by limiting users to a single printing of an image in his terms of use. That would most likely be covered by "fair use".

However if their source is a US government publication (which I expect the US military vehicles are) then these drawings would have already entered the public domain. I will take a look for sources and let you know what I find.

I do know that the the line drawings on my games server are in the public domain, but they are too small for your use.
