Question: Albert Lee Ueltschi was enshrined at Dayton, Ohio along with which American pilot who served in the United States Air Force and test pilot for the North American X-15 program?
Context: The U.S. Air Force Test Pilot School (USAF TPS) is the Air Force's advanced flight training school that trains experimental test pilots, flight test engineers, and flight test navigators to carry out tests and evaluations of new aerospace weapon systems and also other aircraft of the U.S. Air Force.  This school was established on 9 September 1944 as the Flight Test Training Unit at Wright-Patterson Air Force Base (AFB) in Dayton, Ohio.  To take advantage of the uncongested skies, usually superb flying weather, and the lack of developed zones in the event of crashing, the test pilot school was officially moved to its present location at Edwards Air Force Base in the northwestern Mojave Desert of Southern California on 4 February 1951. Robert Aitken "Bob" Rushworth (October 9, 1924 – March 18, 1993), (Maj Gen, USAF), was an American World War II, Korean War and Vietnam War pilot, mechanical and aeronautical engineer, and United States Air Force test pilot for the North American X-15 program. William Harvey "Bill" Dana (November 3, 1930 – May 6, 2014) was an American aeronautical engineer, U.S. Air Force pilot, NASA test pilot, and astronaut in the X-20 Dyna-Soar, and North American X-15 programs. Joseph Albert "Joe" Walker (February 20, 1921 – June 8, 1966) flew the world's first two spaceplane flights in 1963, thereby becoming the United States' seventh man in space.  Walker was a Captain in the United States Air Force, an American World War II pilot, an experimental physicist, a NASA test pilot, and a member of the U.S. Air Force Man In Space Soonest spaceflight program.  His two X-15 experimental rocket aircraft flights in 1963 that exceeded the Kármán line – the altitude of 100 km , generally considered to mark the threshold of outer space – qualified him as an astronaut under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale (FAI). Albert Lee "Al" Ueltschi (May 15, 1917 – October 18, 2012) is considered the father of modern flight training and was the founder of FlightSafety International.  Ueltschi was once personal pilot to Juan Trippe and an associate to Charles Lindbergh.  On July 21, 2001, he was enshrined at Dayton, Ohio, in the National Aviation Hall of Fame class of 2001, along with test pilot Joe Engle, United States Air Force flying ace Marion Carl, and USAF ace Robin Olds.  In 2013, "Flying" magazine ranked Ueltschi number 13 on its list of the "51 Heroes of Aviation". 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. Kenneth O. "K.O." Chilstrom (born April 20, 1921) is a retired United States Air Force officer, combat veteran, test pilot, and author.  He was the first USAF pilot to fly the XP-86 Sabre, chief of fighter test at Wright Field, commandant of the U.S. Air Force Test Pilot School, and program manager for the XF-108 Rapier.  Chilstrom was a pilot in the first jet air race and delivered the first air mail by jet.  He flew over eighty combat missions in the Italian Campaign of World War II and tested over twenty foreign models of German and Japanese fighters and bombers to evaluate their strengths and weaknesses. Joe Henry Engle (born August 26, 1932), (Maj Gen, USAF, Ret.) , is an American pilot who served in the United States Air Force, test pilot for the North American X-15 program, aeronautical engineer, and a former NASA astronaut.  As of 2017, he is the last living pilot of the X-15 program. Robert Michael "Bob" White (July 6, 1924 – March 17, 2010), (Maj Gen, USAF), was an American military aircraft test pilot, fighter pilot, electrical engineer, and a Major general in the United States Air Force.  White broke a number of records with the North American X-15 experimental aircraft during the 1960s, and supervised the design and development of several modern military aircraft. The Royal Australian Air Force's Aircraft Research and Development Unit (ARDU) plans, conducts and analyses the results of ground and flight tests of existing and new Air Force aircraft.  ARDU consists of four flights located at RAAF Bases Edinburgh, Amberley, Richmond and Williamtown, staffed by qualified test pilots, flight test engineers and flight test system specialists.  Up until 2016 the Squadron also conducted flight test for the Australian Army with Army personnel also working within the unit.  The flight test crew are long course trained at test pilot schools including the United States Air Force Test Pilot School, the United States Naval Test Pilot School, the Empire Test Pilots' School, the École du personnel navigant d'essais et de réception and the National Test Pilot School.
