Elliot McKay See Jr. (July 23, 1927 February 28, 1966) was an American engineer, naval aviator, test pilot, and NASA astronaut, selected in the second group of astronauts.
 Chosen as the prime command pilot for what would have been his first space flight, Gemini 9, he was killed with his crewmate Charles Bassett in a 1966 NASA trainer jet crash at the St. Louis, Missouri McDonnell Aircraft plant, where they were to take two weeks of space rendezvous simulator training.
Soyuz 9 (Russian: Союз 9 , "Union 9") was a 1970 Soviet manned space flight.
 The two-man crew of Andrian Nikolayev and Vitali Sevastyanov broke the five-year-old space endurance record held by Gemini 7, with their nearly 18-day flight.
 The mission paved the way for the Salyut space station missions, investigating the effects of long-term weightlessness on crew, and evaluating the work that the cosmonauts could do in orbit, individually and as a team.
 It was also the last flight of the first-generation Soyuz 7K-OK spacecraft, as well as the first manned space launch to be conducted at night.
 To date, Soyuz 9 marks the longest manned flight by a solo spacecraft.
Lowell Herbert Smith (October 8, 1892—November 4, 1945) was a pioneer American airman who piloted the first airplane to receive a complete mid-air refueling (along with Lt. John P. Richter) on June 27, 1923, and later set an endurance record of 37 hours on August 28, both in a De Havilland DH-4B.
 Smith also piloted the Douglas World Cruiser "Chicago", which along with one other made the first aerial circumnavigation in 1924.
 Smith held 16 records for military aircraft in speed, endurance and distance.
 He was awarded the best achievement in flight Mackay Trophy twice.
Gemini 9A (officially Gemini IX-A) was a 1966 manned spaceflight in NASA's Gemini program.
 It was the 7th manned Gemini flight, the 13th manned American flight and the 23rd spaceflight of all time (includes X-15 flights over 100 km ).
 The original crew for Gemini 9, command pilot Elliot See and pilot Charles Bassett, were killed in a crash on February 28, 1966 while flying a T-38 jet trainer to the McDonnell Aircraft plant in St. Louis, Missouri to inspect their spacecraft.
 The mission was flown June 3–6, 1966 by backup command pilot Thomas P. Stafford and pilot Eugene Cernan.
 The astronauts rendezvoused with the Augmented Target Docking Adaptor, but were unable to dock with it because the nose fairing failed to eject from the docking target due to a launch preparation error.
 Cernan performed a two-hour extravehicular activity, during which he was planned to demonstrate free flight in a self-contained rocket pack, the Astronaut Maneuvering Unit.
 He was unable to accomplish this due to stress, fatigue, and overheating.
Soyuz 18 (Russian: Союз 18 , "Union 18") was a 1975 Soviet manned mission to Salyut 4, the second and final crew to man the space station.
 Pyotr Klimuk and Vitali Sevastyanov set a new Soviet space endurance record of 63 days and the mark for most people in space simultaneously (seven) was tied during the mission.
James Vincent Hartinger (April 17, 1925October 9, 2000) was a United States Air Force general who served as Commander in Chief, North American Air Defense Command (CINCNORAD) from 1980 to 1981; Commander in Chief, North American Aerospace Defense Command (CINCNORAD) from 1981 to 1982; North American Aerospace Defense Command/Commander, Air Force Space Command (CINCNORAD/COMAFSPC) from 1982 to 1984.
 He was a command pilot with more than 5,000 flying hours and was the first recipient of the Master Space Badge.
Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999), (Captain, USN), was an American NASA astronaut, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon.
 He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on the Gemini 5 mission, and commanded the Gemini 11 mission.
 After Apollo, he commanded the Skylab 2 mission (the first manned one), on which he and his crewmates repaired significant launch damage to the Skylab space station.
 For this, President Jimmy Carter awarded him the Congressional Space Medal of Honor in 1978.
Frank Frederick Borman II (born March 14, 1928), (Col, USAF, Ret.)
, is a retired United States Air Force pilot, aeronautical engineer, test pilot, and NASA astronaut, best remembered as the Commander of Apollo 8, the first mission to fly around the Moon, making him, along with crew mates Jim Lovell and Bill Anders, the first of only 24 humans to do so.
 Before flying on Apollo, he set a fourteen-day spaceflight endurance record on Gemini 7, and also served on the NASA review board which investigated the Apollo 1 fire.
 After leaving NASA, he was the Chief Executive Officer (CEO) of Eastern Air Lines from 1975 to 1986.
 Borman is a recipient of the Congressional Space Medal of Honor.
Evelyn "Bobbi" Trout (January 7, 1906–January 24, 2003) was an early American aviator, notable for her pioneering flying activities.
 Trout began her aviation career at the age of 16; however, her first solo flight and solo certificate was only given on April 30, 1928.
 In the spring of 1928, Trout’s mother bought her an International K-6 biplane.
 Trout received her pilot's identification card from the United States Department of Commerce on September 1, 1928.
 She was the second woman to break the non-refueling endurance record for women when she flew 12 hours straight from California in 1929.
 The record was previously held by Viola Gentry and was the first record where Fédération Aéronautique Internationale (FAI) rules of the endurance record were revised stating that endurance records had to be broken by a full hour.
 Trout also participated in the Women's Air Derby of 1929, which was dubbed the Powder Puff Derby.
 In 2001, she was recognized as the only living participant in the first Women's Air Derby of 1929.
 Evelyn got her nickname “Bobbi” when she copied the hairstyle of 1928 actress Irene Castle which was a short “Bob” haircut.
Leroy Gordon "Gordo" Cooper Jr. (March 6, 1927 – October 4, 2004), (Col, USAF), better known as Gordon Cooper, was an American aerospace engineer, test pilot, United States Air Force pilot, and one of the seven original astronauts in Project Mercury, the first manned space program of the United States.
