Reference excerpt

William John "Pete" Knight (November 18, 1929 – May 7, 2004) (Col, USAF) was an American aeronautical engineer, politician, Vietnam War combat pilot, test pilot, and astronaut. He was one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the U.S. Air Force and NASA. He was also selected for participation in the X-20 Dyna-Soar program. On October 3, 1967, Knight piloted X-15 Flight 188, the program's fastest flight. Flying at a maximum Mach of 6.7 and a maximum speed of 4,520 mph (7,274 km/h), he set a speed record for flight in a winged, powered aircraft. The flight was made in the X-15A-2, the second of three planes in the X-15 fleet. Two weeks later on October 17, Knight flew X-15 Flight 190, reaching a maximum altitude above 50 miles. This qualified him as an astronaut according to the United States definition of the boundary of space. However, this altitude did not surpass the Kármán line, the internationally accepted boundary of 100 kilometers (62 miles). Knight went on to have a political career in both Palmdale city politics as well as California state level politics. He served four years in the California State Assembly followed by seven and a half years in the California State Senate, dying in office. In spite of having both a brother and a son who are LGBT, Knight's political career is most remembered for his anti-LGBT work, having authored the ballot proposition that became known as the Knight initiative.

Early life and education Knight was born November 18, 1929, in Noblesville, Indiana, to parents William T. Knight (1906–1968) and Mary Emma Knight (1909–1959). Following high school, Knight attended Butler University and Purdue University. He graduated with a Bachelor of Science degree in Aeronautical Engineering from the U.S. Air Force Institute of Technology in 1958.

Personal Knight was married to Helena Stone and they had three sons, Steve, Peter, and David. Helena predeceased Knight. Knight remarried and at his death in 2004 he was survived by his widow Gail, a brother, three sons, four stepchildren and 15 grandchildren.

Air Force career Knight joined the United States Air Force in 1951. While only a second lieutenant, he flew an F-89 at the National Air Show in 1954 and won the Allison Jet Trophy. Starting in 1958, following his graduation from both U.S. Air Force Institute of Technology and the Air Force Experimental Flight Test Pilot School (Class 58C), Knight served as a test pilot at Edwards Air Force Base, California. He was a project test pilot for the F-100 Super Sabre, F-101 Voodoo, F-104 Starfighter and later, T-38 Talon and F-5 Freedom Fighter test programs. In 1960, he was one of six test pilots selected to fly the X-20 Dyna-Soar, which was slated to become the first winged orbital space vehicle capable of lifting reentries and conventional landings. After the X-20 program was canceled in 1963, he completed the astronaut training curriculum through the Aerospace Research Pilot School (Class 63A) at Edwards AFB and was selected to fly the North American X-15. He had more than his share of eventful flights in the X-15. While climbing through 107,000 feet (33,000 m) at Mach 4.17 on June 29, 1967, he suffered a total electrical failure and all onboard systems shut down. After reaching a maximum altitude of 173,000 feet (53,000 m), he calmly set up a visual approach and, resorting to old-fashioned "seat-of-the-pants" flying, he glided down to a safe emergency landing at Mud Lake, Nevada. For his remarkable feat of airmanship that day, he earned a Distinguished Flying Cross.

On October 3, 1967, Knight set a world aircraft speed record for manned aircraft by piloting the X-15A-2 to 4,520 miles per hour (7,274 km/h) (Mach 6.70), a record that still stands today. During 16 flights in the aircraft, Knight also became one of only five pilots to earn their Astronaut Wings by flying an airplane in space, reaching an altitude of 280,500 feet (85,500 m). After nearly ten years of test flying at Edwards AFB, he went to Southeast Asia in 1968, where he completed a total of 253 combat missions in the F-100 during the Vietnam War. Following his combat tour, he served as test director during development of the F-15 Eagle at Wright Patterson Air Force Base in Dayton, Ohio. He also was the program director for the International Fighter (F-5) Program at Wright-Patterson. In 1979, he returned to Edwards AFB, and served as a test pilot for the F-16 Fighting Falcon. After 32 years of service and more than 6,000 hours in the cockpits of more than 100 different aircraft, he retired from the U.S. Air Force as a colonel in 1982.

Political career In 1984, he was elected to the city council of Palmdale, California, and four years later became the city's first elected mayor. In 1992, he was elected to serve in the California State Assembly representing the 36th District. He served in the State Senate representing the 17th District from 1996 until his death on May 7, 2004. Knight's youngest son, Steve Knight served as assemblyman for the 36th Assembly District from 2008 to 2012, the seat previously held by his father.

Proposition 22

Knight's brother and son came out as gay, and Knight pursued anti-LGBT legislation in his political work. During his term in the Senate, Knight gained statewide attention in 2000 as the author of Proposition 22, a.k.a. the "Knight Initiative", the purpose of which was to ban same-sex marriage: "Only marriage between a man and a woman is valid or recognized in California." The proposition passed with 61.4% approval and 38.6% against. On March 9, 2004, Knight's son, David Knight, who is gay, married his partner during the period when San Francisco registered same-sex marriages in defiance of state law. These marriages were nullified by the California Supreme Court in 2004. The Court later found Proposition 22 to be unconstitutional in In re Marriage Cases (2008). Knight's younger brother died of AIDS-related complications in 1995 at age 60. Of his younger brother's homosexuality, Knight said "We never talked about it."

Worked examples

Example 1 — a first encounter with William J. Knight

Start with the simplest possible case. Write down what William J. Knight claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to William J. Knight before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about William J. Knight ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of William J. Knight

In research
William J. Knight appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses William J. Knight in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
William J. Knight is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2004 deaths, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life
Look for William J. Knight outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
