Hakara.
I'm not sure I follow the case you put. How would a rendering from before the raid prove anything to YOU.
If we were to assume that what ever was left at the raid site (be it real or fake) was built before the raid, and maybe at least six months to a year before so how would a pic from before the raid prove anything to you.
The rendering could be a rendering of a fake helicopter.
I'm not really a fan of conspiracies and am happy to accept that he US has the capability and the cash to built a stealth Blackhawk, that they also have a long history of building aircraft that can spend a long time unseen and of using those aircraft on OPs.
To clear things up for me a little are you suggesting the Anericans didn't build the aircraft (even though they have built something similar before) or that they couldn't build it?
