Because this aircraft was way ahead of its time, many new technologies had to be invented specifically for this project – some still in use today. One of the biggest problems that engineers faced at that time was working with Titanium. Kelly Johnson explains, “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”.
Ordinary drills were rendered useless because after about 17 rivet holes the drill would be completely destroyed. During the welding process, an extremely rare and expensive argon shielding gas had to be used to eliminate oxygen from the metal to ensure the highest quality of welds.
A total of 12 out of the 32 aircraft built were lost. The important thing to take note of is that none of the Blackbirds were lost due to enemy military retaliation. All SR-71 crew had to do upon a missile launch, was to increase the throttle and watch the missile get further and further away from striking distance.Originally posted by lincolnboyAfter watching Games of Thrones, makes me glad i was not born in those years.

As mentioned above....An interesting thing about the SR71 was it used titanium primarily, which Russia is the primary supplier of. So the US used shell corporations and other means to purchase titanium from Russia for use to spy on them with the same plane."When the people find that they can vote themselves money, that will herald the end of the republic." -Benjamin Franklin
