<p>Lockheed XF-90 (46-688) in Yucca Flat.
</p><p>This XF-90, a Lockheed experimental aircraft, was exposed to the same nuclear tests as the Yucca Lady. The XF-90, of which only two were ever built, is the sole surviving example of Clarence (Kelly) Johnson's Lockheed Skunk Works second design. The first was the XP-80, which later went into production as the F-80 Shooting Star. The Skunk Works went on to design the U-2, SR-71 (Blackbird) and the F-117 Stealth fighter.
</p><p>Historically, the XF-90 boasts several significant features: it was one of the first to employ an ejection seat; it had a fully adjustable tail, and was the first to use fowler flaps to improve air flow over the ailerons. It was also the first to use wingtip drop tanks on sweptback wings, and the first to employ an afterburner. Today

the broken aircraft rests in two parts in Plutonium Valley; its counterpart was destroyed during structural testing in Ohio. Plans call for the aircraft to be dismantled, decontaminated, and to be placed on display at the U.S. Air Force Museum, Wright-Patterson Air Force Base, Ohio.
