John Barron McKay (December 8, 1922 – April 27, 1975) was an American naval officer and aviator in World War II, test pilot, and one of the first pilots assigned to the X-15 flight research program at NASA's Flight Research Center, Edwards Air Force Base, California.
 As a civilian research pilot and aeronautical engineer, he made 30 flights in X-15s from October 28, 1960, until September 8, 1966.
 His peak altitude was 295,600 feet (55.98 miles), and his highest speed was 3,863 mph (Mach 5.64).
Flight 90 of the North American X-15 was a test flight conducted by NASA and the US Air Force in 1963.
 It was the first of two X-15 missions that reached space, along with Flight 91 the next month.
 The X-15 was flown by Joseph A. Walker, who flew both X-15 spaceflights.
Charles Augustus Lindbergh (February 4, 1902 – August 26, 1974), nicknamed Slim, Lucky Lindy, and The Lone Eagle, 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 making his Orteig Prizewinning nonstop flight from Long Island, New York, to Paris.
 He covered the 33 ⁄ -hour, 3,600 smi alone in a single-engine purpose-built Ryan monoplane, "Spirit of St. Louis".
 This was the first solo transatlantic flight and the first non-stop flight between North America and mainland Europe.
 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.
Alys McKey Bryant (1880–1954) was an American aviator.
 She was the first woman to fly on the Pacific Coast and in Canada, and one of the few female members of the Early Birds of Aviation—individuals who had solo piloted an aircraft prior to December 17, 1916.
 She cut short her brief career as a pilot after her husband, John Bryant, died while performing an air show in Victoria, Canada, in August 1913.
 During World War I she trained pilots.
Douglas Corrigan (January 22, 1907 – December 9, 1995) was an American aviator born in Galveston, Texas.
 He was nicknamed "Wrong Way" in 1938.
 After a transcontinental flight from Long Beach, California, to New York City, he flew from Floyd Bennett Field in Brooklyn, New York, to Ireland, though his flight plan was filed to return to Long Beach.
 He claimed his unauthorized flight was due to a navigational error, caused by heavy cloud cover that obscured landmarks and low-light conditions, causing him to misread his compass.
 However, he was a skilled aircraft mechanic (he was one of the builders of Charles Lindbergh's "Spirit of St. Louis") and had made several modifications to his own plane, preparing it for his transatlantic flight.
 He had been denied permission to make a nonstop flight from New York to Ireland, and his "navigational error" was seen as deliberate.
 Nevertheless, he never publicly admitted to having flown to Ireland intentionally.
X-15 Flight 3-65-97, also known as X-15 Flight 191, was a test flight of the North American X-15 experimental aircraft.
 It took place on November 15, 1967, and was piloted by Michael J. Adams.
 It ended in tragedy when the aircraft broke apart minutes after launch due to technical difficulties, killing the pilot and destroying the plane.
X-15 Flight 91 was a 1963 American manned mission, and the second and final flight in the program to achieve sub-orbital spaceflight—a flight over 100 km in altitude—which was previously achieved during Flight 90 a month earlier.
 It was the highest flight of the X-15 program.
 It was the first flight of a reused spacecraft, as plane number three flew the previous sub-orbital flight on July 19.
 This mission was piloted by Joseph A. Walker on August 22, 1963, with the air-launch occurring from a modified Boeing B-52 Stratofortress support plane over Smith Ranch Dry Lake, Nevada, United States.
 Walker piloted the X-15 to an altitude of 107.96 km and remained weightless for approximately five minutes.
 The altitude was the highest manned flight by a spaceplane to that time and remained the record until the 1981 flight of Space Shuttle Columbia.
 Walker landed the X-15 about 12 minutes after it was launched, at Rogers Dry Lake, Edwards Airforce Base, in California.
 This was Walker's final X-15 flight.
Cygnus CRS Orb-3, also known as Orbital Sciences CRS Flight 3 or Orbital 3, was an attempted flight of Cygnus, an automated cargo spacecraft developed by United States-based company Orbital Sciences, on 28 October 2014.
 This flight, which would have been its fourth to the International Space Station and the fifth of an Antares launch vehicle, resulted in the Antares rocket exploding seconds after liftoff.
Michael James "Mike" Adams (May 5, 1930 – November 15, 1967), (Maj, USAF), was an American aviator, aeronautical engineer, and USAF astronaut.
 He was the first American space mission fatality, according to the United States definition.
Douglas Campbell (June 7, 1896 – December 16, 1990) was an American aviator and World War I flying ace.
 He was the first American aviator flying in an American-trained air unit to achieve the status of ace.
