who completed a transatlantic solo flight in 1927
Charles Lindbergh Charles Augustus Lindbergh (February 4, 1902 – August 26, 1974), nicknamed Lucky Lindy, The Lone Eagle, and Slim[1] was an American aviator, military officer, author, inventor, explorer, and environmental activist. At age 25 in 1927, he went from obscurity as a U.S. Air Mail pilot to instantaneous world fame by winning the Orteig Prize: making a nonstop flight from Roosevelt Field, Long Island, New York, to Paris, France. Lindbergh covered the ​33 1⁄2-hour, 3,600 statute miles (5,800 km) alone in a single-engine purpose-built Ryan monoplane, Spirit of St. Louis. This was not the first flight between North America and Europe, but he did achieve the first solo transatlantic flight and the first non-stop flight between North America and the European mainland. Lindbergh was an officer in the U.S. Army Air Corps Reserve, and he received the United States' highest military decoration, the Medal of Honor, for the feat.[2]
1922 British Mount Everest expedition The 1921 British Mount Everest reconnaissance expedition had seen the whole eastern and northern surroundings of the mountain. In searching for the easiest route, George Mallory, who was also a participant of the 1924 expedition (and the only person on all three expeditions in 1921, 1922 and 1924), had discovered a route which, according to his opinion, would allow an attempt on the summit.
