The SR-71 Blackbird.
Tumblr media
A spy plane that flew at approximately 70 to 85 thousand (21,000 to 25,000 meters) above Earth's sea level and cruised at speeds of 2,500 miles per hour ( 4,000 km per hour) is one man's most most amazing creation in its class for the purposes of intelligence gathering.
Tumblr media
When the enemy fired missiles and other rockets at the Blackbird, the evasive maneuver was simply, acceleration and climbing.
Tumblr media
Nothing could reach this machine that practically flew at the edge of Earth's atmosphere and beginning of solar system space.
Tumblr media
Enemy aircraft would run out of fuel before they could even attempt to get close to the Blackbird.
Tumblr media
Missiles would burn out of rocket fuel. On some instances, the SR-71 outsped missiles and bullets fired at it.
Tumblr media
Architecture, engineering and operation of this machine is phenomenal. Even though we outlived its usefulness, it would be awesome to keep this aircraft functional for demonstration purposes.

SR-71 Blackbird cockpit ! 
Flying at Mach 3.5 Mach, Blackbird's outer surface would heat up to 260 degree centigrade. This would be enough to raise the temperature of the cockpit to 120 degree centigrade. So special focus had to be given to air-conditioning..
The aircraft was mostly built of Titanium. Before the Blackbird, titanium was used sparingly—usually on high-temperature exhaust fairings, and other small parts directly related to supporting, cooling, or shaping high-temperature areas on aircraft. The Blackbird was completely different. This plane was about eighty-five percent Titanium, to be more precise. The other fifteen percent was high-end composite materials.
In their typical undercover fashion, the CIA created several cover-up companies that were used to purchase the required titanium for the Blackbird’s construction. The source of the titanium was, interestingly, the Soviet Union. This is especially ironic because the Blackbird would be used to gather and rely on information about the Soviet Union.  
According to Kelly Johnson, one of the biggest problems that engineers faced at the time was working with titanium. “We produced 6,000 parts, and of them, fewer than ten percent were any good. The material [titanium] was so brittle that if you dropped a piece on the floor it would shatter”, he explained.
There were a couple of other difficulties that they encountered. For example, ordinary drills were useless with titanium, because after about seventeen rivet holes, the drill would be destroyed. Yet another obstruction occurred during the welding process. They eventually figured out that if an extremely rare and expensive argon shielding gas was used, they could ensure the highest quality of welds.

The SR-71 Blackbird's cockpit faced challenges due to its high-speed capabilities, reaching Mach 3.5, causing the outer surface temperature to rise to 260 degrees Celsius. This necessitated effective air-conditioning to maintain a manageable cockpit temperature of 120 degrees Celsius.
Constructed predominantly from titanium, a departure from previous aircraft, the SR-71 was about 85% titanium and 15% high-end composite materials. The procurement of titanium was concealed through CIA-established front companies, notably acquiring it from the Soviet Union, despite the irony that the Blackbird would later be used to gather information about the Soviet Union.
Engineers encountered difficulties working with titanium due to its brittleness, resulting in low-quality parts. Ordinary drills were ineffective, and welding posed challenges until the discovery of using rare argon shielding gas for improved weld quality. These challenges were navigated to create the iconic SR-71 Blackbird.
