D. Calbraith Perry Rodgers

Explanation:

The first crossing of the United States by airplane was achieved by Calbraith Perry Rodgers in 1911. In 1910, famed publishing magnate William Randolph Hearst announced his offer of a $50,000-prize for a U.S. transcontinental flight in thirty days or less. Rodgers' Wright EX biplane was named the Vin Fiz after his sponsor's grape soda product. He left Sheepshead Bay, New York, on September 17, 1911. A "hangar" car, a rolling workshop filled with spare parts to repair and maintain the airplane, followed along. The flight was punctuated by numerous stops, delays, and accidents. When Hearst's 30-day time limit expired, Rodgers had only reached Kansas City, Missouri. Undaunted, he continued on, determined to make the first transcontinental airplane flight whether he received the money or not. He arrived in Pasadena, California, to a hero's welcome, 49 days after setting out. Although Pasadena was the official end of the coast-to-coast journey, Rodgers flew on to Long Beach to complete the flight at the shore of the Pacific Ocean. The total distance covered was 6,914 km (4,321 mi) in 82 hours, 4 minutes, total flying time at an average speed of 82.4 kph (51.5 mph).
