4. **On Tooling:** Because titanium was so brittle and difficult to work with, the Skunk Works had to design entirely new tools and manufacturing techniques just to build the aircraft. — [*Source: \[Lockheed Martin History*](https://www.lockheedmartin.com/en-us/news/features/history/blackbird.html?ref=antoinebuteau.com)*\]*
5. **On Fuel as Coolant:** To survive extreme temperatures, the SR-71 used its own specialized jet fuel as a heat sink to physically cool the airframe. — [*Source: \[Lockheed Martin History*](https://www.lockheedmartin.com/en-us/news/features/history/blackbird.html?ref=antoinebuteau.com)*\]*
6. **On Expanding Metal:** The SR-71's panels were deliberately built with gaps because the airframe expanded by several inches in flight due to extreme thermal friction. — [*Source: \[Lockheed Martin History*](https://www.lockheedmartin.com/en-us/news/features/history/blackbird.html?ref=antoinebuteau.com)*\]*
7. **On Fluid Leaks:** Because the panels were intentionally loose on the ground, the SR-71 famously leaked fuel on the tarmac before taking off and sealing itself at high speeds. — [*Source: \[Lockheed Martin History*](https://www.lockheedmartin.com/en-us/news/features/history/blackbird.html?ref=antoinebuteau.com)*\]*
8. **On Jet Propulsion:** "It became obvious that we would have to design better wings and tails, but that if we wanted higher performance we would have to get rid of the propeller." — [*Source: \[More Than My Share of It All*](https://www.goodreads.com/book/show/711200.Kelly?ref=antoinebuteau.com)*\]*

3. **On Fear and Respect:** "I figured I needed to have hell scared out of me once a year in order to keep a proper balance and viewpoint on designing new aircraft." — [*Source: \[More Than My Share of It All*](https://www.goodreads.com/book/show/711200.Kelly?ref=antoinebuteau.com)*\]*
4. **On Early Validation:** Testing in the real world must happen as soon as possible, as flight conditions frequently reveal flaws that wind tunnels miss entirely. — [*Source: \[Skunk Works: A Personal Memoir*](https://www.goodreads.com/book/show/101438.Skunk%5FWorks?ref=antoinebuteau.com)*\]*
5. **On Responsibility:** The engineers who draft the system must be physically present on the flight line when the test pilots risk their lives flying it. — [*Source: \[Skunk Works: A Personal Memoir*](https://www.goodreads.com/book/show/101438.Skunk%5FWorks?ref=antoinebuteau.com)*\]*
6. **On the Initial Flight:** The true test of a flying machine is not the theoretical blueprint, but how it handles the unforgiving aerodynamic realities of the sky. — [*Source: \[Skunk Works: A Personal Memoir*](https://www.goodreads.com/book/show/101438.Skunk%5FWorks?ref=antoinebuteau.com)*\]*
7. **On Customer Pilots:** Test the aircraft yourself first; never hand over an unproven, dangerous prototype to the military for initial flight testing. — [*Source: \[Kelly's 14 Rules*](https://www.lockheedmartin.com/en-us/who-we-are/leadership-governance/skunk-works-leadership.html?ref=antoinebuteau.com)*\]*
8. **On Honesty in Testing:** If a flight test fails, admit it immediately to the customer without attempting to spin the results. — [*Source: \[Skunk Works: A Personal Memoir*](https://www.goodreads.com/book/show/101438.Skunk%5FWorks?ref=antoinebuteau.com)*\]*
9. **On Compressibility:** When the P-38 encountered extreme drag and control loss in dives, Johnson personally participated in high-speed flight tests to diagnose the aerodynamic crisis. — [*Source: \[Lockheed Martin History*](https://www.lockheedmartin.com/en-us/news/features/history/p-38.html?ref=antoinebuteau.com)*\]*
