From the LA Times obituary:
Scott Crossfield, a legendary test pilot who became the first man to fly at twice the speed of sound in 1953 and later flew and helped design the X-15 rocket-powered research aircraft, was found dead Thursday in the wreckage of his single-engine plane in mountains near Ranger, Ga. He was 84.
Crossfield's plane, a Cessna 210A, was found about 50 miles northwest of Atlanta a day after it dropped off radar screens during a flight from Alabama to Virginia, authorities said Thursday. There were thunderstorms in the area when radar contact was lost; the cause of the crash was under investigation.
