Undetectable, three times faster than sound: the SR-71 Blackbird
Can you imagine flying around the world in less than 12 hours?
The remarkable project of the Lockheed Corporation made it possible, with the fastest aircraft in the world to this day. During the Cold War, the Central Intelligence Agency (CIA) demanded to develop a reconnaissance plane that could fly above 27,000 meters at high speed, since the Soviet Union detected its previous U-2. This titanium-skinned Blackbird that mostly reminds of a spaceship rather than a spy plane still holds a couple of world’s records in aviation until today.
