Below are a collection of highly classified articles that I have managed to obtain. These culminate in a letter from Lt. General. Darrell K. Williams detailing the actual intent behind Project Aurora!
Maj. Gen. John A. Samford's Statement on "Flying Saucers", Pentagon, Washington, DC, 07/31/1952
Pre July 1947 photographic evidence of a craft over Roswell, New Mexico.
As you can see from the wiki page (link below) about The Aurora Project, the US government have been ploughing a lot of money into this project. It was never going to be cheap rebuilding an alien craft but someone slipped up and the figures appeared in the US’s 1985 budget. The Aurora Project was quickly explained away as simply a military code name for the stealth bomber, something we know not to be true!!!
