Back to #419 Kelly Johnson: Skunk Works, with David Senra.
What Is the SR-71 Blackbird?
David Senra says the SR-71 Blackbird is the airplane Kelly Johnson and Skunk Works created during LBJ's presidency. It flies at three times the speed of sound. It was the most advanced aircraft in the world at the time, and it is still the fastest. At 80,000 feet, the team was not only inventing a product. They had to invent the manufacturing methods too. Everything about the aircraft had to be invented.
Senra reads Johnson's list: special fuels, structural materials, manufacturing tools and techniques, hydraulic fluid, fuel tank sealants, paints, plastics, wiring, and connecting plugs, along with the basic aircraft and engine design. During that work Johnson went back to an old axiom, keep it simple, stupid. The more complexity, the more potential for problems.
