The Lockheed A-12, SR-71, and Pratt & Whitney JT11D-20 (J58 Military Designation)

 

These photographs and other related data do not constitute a technical look at the A-12/SR-71 propulsion system, but a view of the beauty and complexity of the most outstanding aeronautic system yet engineered. In most cases each photograph represents a part of the overall system that was hand made, just as any other piece of art.
