Background: On April 8, 1931, Amelia Earhart set an official world autogyro altitude record of 18,415 feet (5,613 meters) over Willow Grove, Pennsylvania, piloting a 300-horsepower Pitcairn PCA-2 autogyro named "Beech-Nut". This pioneering flight—where her onboard barograph nearly reached 19,000 feet—shattered prevailing skepticism around the early, unpowered-rotor precursors to modern helicopters, decisively proving that autogyros possessed both extreme vertical performance and high-altitude stability beyond low-level novelties. By capitalizing on this technical breakthrough, Earhart seamlessly segued into a historic coast-to-coast flight later that spring, becoming the first woman to cross the United States in an autogyro and fundamentally changing public perception of rotary-wing aviation.
