The XF-90 was built like no fighter before… or since.At a time when no one knew what supersonic flight would do to metal, Skunk Works chose brute force over guesswork. They forged the strongest airframe on Earth: 75S aluminum over a steel spine, the fuselage braced until it was closer to armor than aircraft.It was forged to be at least 50 percent stronger than any warplane in the entire world. It was meant to ride with the giant B-36 Peacemaker, to dive beyond the speed of sound and deliver nuclear fire across the globe.Then, in 1952, a blinding flash lit up its aluminum skin. The tail quivered, and the landing gear trembled like Jell-O as a shockwave equal to thousands of tons of TNT smashed into its airframe, followed by a mushroom cloud rising into the sky. It was time to see if the strongest plane in the world could take a nuclear blast. —Join Dark Skies as we explore the world of aviation with cinematic short documentaries featuring the biggest and fastest airplanes ever built, top-secret military projects, and classified missions with hidden untold true stories.
