The SR-71 Blackbird: The Fastest Plane on Planet Earth











There are a number of video clips at the end of the  article that are immensely informative and very entertaining.

15 Fascinating Facts About The SR-71 Blackbird, The Fastest Plane On Earth


1. The SR-71 Blackbird aircraft was built by Lockheed Martin and took its first flight in 1964. It was retired by NASA in 1999.




The SR-71 Blackbird is still the fastest plane that has ever flown and served an important role in history as a spy plane. Its first test flight was on December 22, 1964 and was never once hit by a missile during its 25 years of service.Though these awesome planes haven’t left the ground since before the turn of the century, they’re still worth all the recognition of being the fastest plane on Earth.



2. It is the fastest planes that ever took flight. The official fastest record it holds is 2,193.13 mph on July 1976. The photo below was taken right after it reached that record.









3. It earned its nickname “Blackbird” because of how stealth it was. It was also extremely quiet inside the cockpit, according to pilot Richard Graham. “You could hear a pin drop. The view is spectacular, being able to see the curvature of the Earth and the black space above filled with stars,” he said.


 

4. The Blackbird was able to map terrain like a side-scanning sonar, aim a radar up to 45 degrees to the side, and interrupt enemy communication and radar signals.


      




5. It was built to fly up to Mach 3.4 speeds (approx. 2,500 mph on land).









6. Over 4,000 missiles were fired at the Blackbird in the 25 years it was flown, but none ever hit it. The Blackbird was just too fast and its evasive tactic was just to speed up until the missile couldn’t keep up with it.










7. Its navigation system called “R2-D2” had a sensor so powerful that it could detect up to 61 stars in broad daylight while the plane was still on the ground.


 






8. The plane required a large amount of titanium to be built so the CIA created fake companies around the world to buy metal from the USSR, which was the biggest supplier, as well as the United States’ enemy at that time.









9. The plane was covered in over 60 pounds of black paint because the black helped cool down the plane by up to 86 degrees. Traveling at over Mach 3, the plane could hit as high as 1,000 degrees without the black paint dissipating the heat.








10. The SR-71 constantly leaked fuel while not in flight due to the contraction of its titanium skin. The tank was designed to expand as it heated up due to air friction. The SR-71 had enough fuel to take off and then get refueled up in the air by a tanker.







11. Its tires were specially designed for the SR-71. Their material was made of aluminum powder which was impregnated to reject heat. This additive gave its unique appearance of silver coloration.







12. There were only 32 Blackbirds ever built. One of the pilots, test pilot Bob Gilliland, is photographed here.





13. Even though it leaked fuel, the fuel had such a high flash point that it would not ignite even if it was hit with fire.



14. To work on the plane as a crew member, you needed to be between the ages of 25 and 40, be married and be “emotionally stable.”


 

15. The camera on the Blackbird was so advanced that when it took a photo of a car on the ground that was 80,000 feet below it and the plane traveled at over 2,000 mph, the license plate would be visible in the photo.
