A couple of points
1. The A-11/SR-71 first flew on the 26th April 1962, as far as I know.
2. This aircraft (Aurora)is acquirable, visually, so from where does it operate? Please don't say AREA-51 or S-4.
3. We all know the vast number of sub-contactors for Euro-fighter, so where are they for this project.
4. The B-2 was wheeled out and shown to the press before it's first flight, in 1988 and the project was made public in 1981.
5. The USAF did this because they said they had no way to "Covertly test fly and aircraft of that size." - How big is Aurora?
