Given the question: Information:  - Clarence Leonard `` Kelly '' Johnson ( February 27 , 1910 -- December 21 , 1990 ) was an American systems and aeronautical engineer . He is recognized for his contributions to a series of important aircraft designs , most notably the Lockheed SR - 71 Blackbird . Besides the first production aircraft to exceed Mach 3 , he also produced the first fighter capable of Mach 2 , the United States ' first operational jet fighter , as well as its first successful twin - engine fighter , and many other contributions to a large number of aircraft . As a member and first team leader of the Lockheed Skunk Works , Johnson worked for more than four decades and is said to have been an `` organizing genius '' . He played a leading role in the design of over forty aircraft , including several honored with the prestigious Collier Trophy , acquiring a reputation as one of the most talented and prolific aircraft design engineers in the history of aviation . In 2003 , as part of its commemoration of the 100th anniversary of the Wright Brothers ' flight , Aviation Week & Space Technology ranked Johnson 8th on its list of the top 100 `` most important , most interesting , and most influential people '' in the first century of aerospace . Hall Hibbard , Johnson 's Lockheed boss , referring to Johnson 's Swedish ancestry once remarked to Ben Rich : `` That damned Swede can actually see air . '' Johnson also helped to design the Lockheed AQM - 60 Kingfisher a decade before the famous SR - 71 . The Kingfisher was a highly successful single engine Mach 4.3 capable Ramjet composed mainly of steel , which was used to test American air defenses against nuclear missiles . The information and experience Johnson gained was later used to produce the A- 12 spy plane for the Central Intelligence Agency . Johnson then used the combined knowledge of the Kingfisher and A- 12 to produce the SR - 71 Blackbird , his most famous aircraft .  - The Lockheed Corporation (originally the Loughead Aircraft Manufacturing Company) was an American aerospace company. Lockheed was founded in 1912 and later merged with Martin Marietta to form Lockheed Martin in 1995.  - Benjamin Robert "Ben" Rich (June 18, 1925  January 5, 1995) was the second Director of Lockheed's Skunk Works from 1975 to 1991, succeeding its founder, Kelly Johnson. Regarded as the "father of stealth," Rich was responsible for leading the development of the F-117, the first production stealth aircraft. He also worked on the F-104, U-2, A-12, SR-71, and F-22, among others. He is the author of "".  - The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters. The fifth-generation combat aircraft is designed to perform ground attack and air defense missions. It has three main models: the F-35A conventional takeoff and landing (CTOL) variant, the F-35B short take-off and vertical-landing (STOVL) variant, and the F-35C carrier-based Catapult Assisted Take-Off But Arrested Recovery (CATOBAR) variant. On 31 July 2015, the United States Marines declared ready for deployment the first squadron of F-35B fighters after intensive testing. On 2 August 2016, the U.S. Air Force declared its first squadron of F-35A fighters combat-ready.  - The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and did its final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.  - Willis Moore Hawkins (December 1, 1913  September 28, 2004) was an aeronautical engineer for Lockheed for more than fifty years. He was hired in 1937, immediately after receiving his bachelor's degree in aeronautical engineering from the University of Michigan. Prior to that, he was in the first graduating class of The Leelanau School, a boarding school in Glen Arbor, Michigan. He contributed to the designs of a number of historic Lockheed aircraft, including the Constellation, P-80 Shooting Star, XF-90, F-94 Starfire, and F-104 Starfighter. During World War II, he was part of the group of Lockheed designers who designed the first American attempt at a jet plane, the Lockheed L-133.  - The Collier Trophy is an annual aviation award administered by the U.S. National Aeronautic Association (NAA), presented to those who have made "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year."  - Kansas is a U.S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name (natively "") is often said to mean "people of the wind" or "people of the south wind", although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison.  - Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.  - Hall Livingstone Hibbard (July 25, 1903  June 6, 1996) was an engineer and administrator of the Lockheed Corporation beginning with the company's purchase by a board of investors led by Robert E. Gross in 1932. Born in Kansas, he received a bachelor's degree in mathematics and physics at the College of Emporia in 1925. He graduated from the Massachusetts Institute of Technology two years later. He worked for Stearman as a draftsman, before joining Robert Gross' Viking Flying Boat Company. He served on the board of the newly revived Lockheed Corporation and led the design departments as chief engineer. Engineers such as Clarence "Kelly" Johnson and Willis Hawkins worked under him.  - The National Aeronautic Association of the United States (NAA) is a non-profit 501(c)(3) organization and a founding member of the Fédération Aéronautique Internationale (FAI). Founded in 1905, it is the oldest national aviation club in the United States and one of the oldest in the world, it serves as the Aeroclub of the United States and, by its Mission Statement it is "dedicated to the advancement of the art, sport and science of aviation in the United States. The NAA is headquartered at the Ronald Reagan Washington National Airport, in Washington, D.C.  - Skunk Works is an official alias for Lockheed Martin's Advanced Development Programs (ADP), formerly called Lockheed Advanced Development Projects. Skunk Works is responsible for a number of famous aircraft designs, including the U-2, the Lockheed SR-71 Blackbird, the Lockheed F-117 Nighthawk, Lockheed Martin F-22 Raptor, and the Lockheed Martin F-35 Lightning II, which will be used in the air forces of several countries. Production is expected to last for up to four decades. The name "Skunk Works" was taken from the moonshine factory in the comic strip "Li'l Abner". The designation "skunk works" or "skunkworks" is widely used in business, engineering, and technical fields to describe a group within an organization given a high degree of autonomy and unhampered by bureaucracy, tasked with working on advanced or secret projects.  - Li'l Abner was a satirical American comic strip that appeared in many newspapers in the United States, Canada and Europe, featuring a fictional clan of hillbillies in the impoverished mountain village of Dogpatch, USA. Written and drawn by Al Capp (19091979), the strip ran for 43 years, from August 13, 1934 through November 13, 1977. It was distributed by United Feature Syndicate. Comic strips typically dealt with northern urban experiences before Capp introduced Li'l Abner, the first strip based in the South. Although Capp was from Connecticut, he spent 43 years writing about a fictional southern town. The comic strip had 60 million readers in over 900 American newspapers and 100 foreign papers in 28 countries. Author M. Thomas Inge says Capp "had a profound influence on the way the world viewed the American South."  - The Lockheed SR-71 "Blackbird" was a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.  - Lockheed Martin is an American global aerospace, defense, security and advanced technologies company with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in Bethesda, Maryland, in the Washington, DC, area. Lockheed Martin employs 126,000 people worldwide. Marillyn Hewson is the current President and Chief Executive Officer.  - The Lockheed F-117 Nighthawk is a single-seat, twin-engine stealth attack aircraft that was developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). The F-117 was based on the "Have Blue" technology demonstrator, and was the first operational aircraft to be designed around stealth technology. The maiden flight of the Nighthawk took place in 1981, and the aircraft achieved initial operating capability status in 1983. The Nighthawk was shrouded in secrecy until it was revealed to the public in 1988.  - Aeronautics (from the ancient Greek words  "r", which means "air", and  "nautik" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)."   - The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts. Founded in 1861 in response to the increasing industrialization of the United States, MIT adopted a European polytechnic university model and stressed laboratory instruction in applied science and engineering. Researchers worked on computers, radar, and inertial guidance during World War II and the Cold War. Post-war defense research contributed to the rapid expansion of the faculty and campus under James Killian. The current campus opened in 1916 and extends over along the northern bank of the Charles River basin.    What entity does 'kelly johnson ' has the relation 'employer' with?
