Hughes was not a stranger to setting records. Another record was set by Hughes in 1937. He set a transcontinental record; making the world’s greatest long-distance speed flight from Los Angelas to Newark, New Jersey. It took him seven hours and twenty-eight minutes, an improvement from his own record. In
1938, Hughes took three days and nineteen hours to fly around the world. In 1939, Hughes purchased a share of the Trans World Airlines stock for $7 million and took control of the airlines, but later he was told by the federal court to sell his shares. In 1942-43, Hughes designed an American fighter and bomber plane, named Hughes D-2. The plane never passed the flight test but paved the say for high prototype military reconnaissance aircraft, Hughes XF-11.
The XF-11 was designed for the United Sates Air Force. In 1943, only two prototypes were subjected to Senate investigation, out of one hundred orders. During his 1946 flight on his XF-11, Hughes crashed the aircraft in Beverly Hills California and sustained serious injuries. This was a turning point for Hughes mental health. Many of his colleagues noticed changes in him that showed behavior similar to Obsessive Compulsive Disorder and an uncanny fear of germs.
