Our Hill AFB SR-71 “Blackbird” T-Shirts are one of our biggest sellers. This plane is by far one of the most remarkable aircraft ever made. The “Blackbird” performed missions at altitudes 16 miles above the surface of Earth and at record speeds in excess of Mach 3. Decades after its introductions this amazing aircraft still holds the official records for speed and altitude for air-breathing machines. The T-shirt is comfortable and washes up great.
