The U.S. Air Force and Pratt & Whitney ground-tested the first uncooled hydrocarbon-fueled scramjet engine at simulated Mach 4.5–6.5 in 2001. This collaboration also demonstrated in 2003 a scramjet made from nickel-based alloys and cooled by its JP7 jet fuel. The 2003 engine has the potential to power future missiles, aircraft, and access-to-space vehicles. Last year, the Defense Advanced Research Projects Agency, U.S. Navy, Boeing, Aerojet, and Johns Hopkins University also ground-tested a scramjet engine, which was constructed primarily from nickel alloys, powered by JP10 jet fuel, and intended exclusively for hypersonic missiles.
Any how, back into the topic at hand, the fuel is still made, so what are they refueling if not Black Birds?

No disrespect Zaphod but actually I believe that the person who gave me the information about it being in use is a bit more , ahem, truthful than the US Goverment.... They do lie you know?! and this person was interested because they know that i'll dig around, they just gave me a pointer in the right direction... they have two SR-71's at Akatori.

How are you going to hide a non-stealthy plane flying at Mach 3+ from an air traffic controller? Or are they forcing hundreds of controllers to lie about them flying?

, but they are probably in the stage of designing a new one, or just using satellites

Scramjet Mach 6 perhaps. Black bird is only mach 3 right?

For a plane that is supposidly no longer in use, it is very funny that several air bases, seem to have dozens that look flight ready

Thats not true CT. Radar can even pick up flocks of birds. Do they have transponders?
What about other countries military aircraft. They can be picked up on US radar. I highly doubt they would be flying with any kind of transponders functioning at all.

SR-71 Grounded, On April 15, 1996, Deputy Secretary of Defense John White directed the Air Force to ground the Air Force's SR-71s due to conflicting language in section 304 of the National Security Act of 1947, which states that the DoD may not obligate or expend funds for any intelligence program, even though it has been appropriated, unless there is an independent authorization for that intelligence related activity. Also complicating this is the "Intelligence Authorization Act" which gives the force of law to the conference report accompanying the act. Also Section 102 of the Intelligence Authorization Act for FY-96 provides funding for the modification of the SR-71, but no funding for operating the SR-71. All operations have been suspended, there will be no training, or operational flights, (test flights related to the modification to the SR can still be carried out, though) till the language conflict has been resolved! -Inside the Air Force; and Richard Graham; and Aviation Week & Space Technology

Final USAF SR-71 flight, Major Bert Garrison(Pilot) and Capt Domingo Ochotorena(RSO) flew SR-71A #967, on the Brandy route, duration of 4.1hours, Tom McLeary flew the chase aircraft, and Ted Carlson photographed the flight(at the time no one knew that this would be the final flight!) (BG)

Googlemaps:
list of blackbirds on runways and in open air storage
seems some of these look quite ready to fly, since they are on runway paths
