Douglas X-3 Stiletto, the first titanium aircraft

“The Douglas X-3 Stiletto was a 1950s United States experimental jet aircraft with a slender fuselage and a long tapered nose, manufactured by the Douglas Aircraft Company. Its primary mission was to investigate the design features of an aircraft suitable for sustained supersonic speeds, which included the first use of titanium in major airframe components. Douglas designed the X-3 with the goal of a maximum speed of approximately 2,000 m.p.h,[2] but it was, however, seriously underpowered for this purpose and could not even exceed Mach 1 in level flight.[3] Although the research aircraft was a disappointment, Lockheed designers used data from the X-3 tests for the Lockheed F-104 Starfighter which used a similar trapezoidal wing design in a successful Mach 2 fighter.” -wikipedia

So, it’s a plane that was made mostly of titanium, and it researched inertia coupling, which caused spinning out at high speeds. (This isn’t in SimplePlanes.) The real thing was supposed to be able to get to Mach 2, but the engines were too heavy, so they had to have weaker ones that didn’t even allow Mach 1 in level flight. but even if the real thing didn’t live up to it’s design, mine did! I added more detail than ever before, and this thing is sleek as ever! Enjoy!
