Question: This builder of the Rutan Boomerang has this number of aircraft on display in the National Air and Space Museum?

full_context: Document 1: Lockheed Martin F-22 Raptor: 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 conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
Document 2: Santos-Dumont number 6: The Santos-Dumont No. 6 was an airship designed and built by the Brazilian pioneer aviator Alberto Santos-Dumont. In 1901 it was used by him to win the Deutsch de la Meurthe prize for a return from Parc Saint Cloud to the Eiffel Tower and back. It is considered by many to be the first truly successful airship.
Document 3: Horten H.VI: The Horten H.VI was a flying wing aircraft designed by the Horten brothers during World War II.
Document 4: Steve Wright Stagger-Ez: Stagger-EZ is a unique three place pusher canard aircraft, featuring staggered seating, a dihedral canard, and a rounder fuselage which differs from other canard aircraft in its class (e.g. Cozy MK IV, Velocity, Long-Ez). The aircraft has standard LongEZ wings and a redesigned fuselage. It was designed by a composite craftsman and pilot by the name of Steve Wright. After completing a VariEZe, Steve Wright found it to be a good design but small and lacking in features he wanted. He flew over a thousand hours in his VariEZe but wanted to build a second canard. He learned that a couple of pilots had suffered broken legs in Long-EZ accidents. So Steve began his design of a new canard that would incorporate several improvements. In 1999 he started by laying a keel down the center of the composite fuselage, which in turn caused the nose wheel to be moved to the right several inches. That improved legroom for the PIC position on the left. The reduced area on the right floor board did not allow for dual rudder pedals. The rods that control the elevator and aileron where positioned in a center console rather than down each side like a Cozy III. The right seater stick is 13 inches behind the left seater. Thus the right seat is "Staggered" back 13 inches. Lastly, a third seat is in the back behind the left seat. With a 42 inch wide fuselage, Steve ordered a custom canopy be made that is at least 20% larger than a Cozy III. The canopy does not open to the side, but is electric and moves up and back like many jet aircraft. Another major change was made to the landing gear. It was moved out and anchored in the strake area. (Any rocks or debris kicked up by the main landing gear are outside of the propeller arc.) Steve also incorporated a simpler fuel system. A central sump connects both fuel tanks. So the Stagger EZ has only one fuel cap but still holds 43 gallons. The Stagger EZ flew for the first time in 2004. Steve flew the Stagger EZ to EAA's "Sun-N-Fun" Fly-In and received "Grand Champion" in the home built category in 2005. Steve and Patricia Wright flew the Stagger EZ until 2009 when Steve came down with cancer. Steve died from melanoma cancer in May 2010. David Williford purchased the StaggerEZ in May 2011. He flew it for 50 hours before having to ground it for a major restoration which lasted almost two years. The Stagger EZ still flies today because of both Steve Wright and David Williford.

Document 5: Virgin Atlantic GlobalFlyer: The Scaled Composites Model 311 Virgin Atlantic GlobalFlyer (registered N277SF) is an aircraft designed by Burt Rutan in which Steve Fossett flew a solo nonstop airplane flight around the world in 2 days 19 hours and 1 minute (67 hours 1 minute) from February 28 to March 3, 2005. The flight speed of 590.7 kph set the world record for the fastest nonstop non-refueled circumnavigation, beating the mark set by the previous Rutan-designed Voyager aircraft at 9 days 3 minutes and an average speed of 116 mph .
Document 6: Teledyne Ryan Scarab: The Teledyne Ryan Model 324 Scarab is a jet-powered reconnaissance UAV developed in the United States in the 1980s for sale to Egypt. The Scarab is a medium-range reconnaissance asset, similar in operational concept to the old Ryan FireFly UAVs, but implemented with improved technology. It was designed to Egyptian Air Force requirements, and was first flown in 1988. 56 were delivered and the type remains in service. It is a neat UAV with low-midbody-mounted swept wings, a twin-fin tail, and a rear-mounted Teledyne CAE 373-8C turbojet engine with the intake on the rear spine of the UAV. Launch is by RATO booster, and recovery by parachute. The aircraft's guidance is pre-programmed, but a radio-control backup system is provided.
Document 7: Rutan Boomerang: The Rutan Model 202 Boomerang is an aircraft designed and built by Burt Rutan . The design was intended to be a multi-engine aircraft that in the event of failure of a single engine would not become dangerously difficult to control due to asymmetric thrust. The result is an asymmetrical aircraft with a very distinct appearance.
Document 8: Bede Aircraft: Bede Aircraft Corporation was founded by controversial aeronautical engineer Jim Bede in 1961 to produce the BD-1 kit aircraft, which eventually became the American Aviation Corporation's AA-1. The company also created and produced a number of advanced kit planes including the famous Bede BD-5 (pusher propeller driven) and BD-5J (turbojet driven). The BD-5J has held the Guinness record as the World's Smallest Jet Aircraft for more than a quarter century. Versions of it saw use in various Budweiser commercials (the Bud Light Jet, which was lost in an inflight fire and crash unrelated to airshow work). The tiny jet also appeared in two James Bond movies; "Octopussy" starring Sir Roger Moore, and later in a cameo appearance, hanging from the wall of Q's workshop in "Die Another Day" starring Pierce Brosnan as Agent 007.
Document 9: National Air and Space Museum: The National Air and Space Museum of the Smithsonian Institution, also called the NASM, is a museum in Washington, D.C.. It holds the largest collection of historic aircraft and spacecraft in the world. It was established in 1946 as the National Air Museum and opened its main building on the National Mall near L'Enfant Plaza in 1976. In 2016, the museum saw approximately 7.5 million visitors, making it the second most visited museum in the world, and the most visited museum in the United States. The museum contains the Apollo 11 command module, the "Friendship 7" capsule which was flown by John Glenn, Charles Lindbergh's "The Spirit of St. Louis", the Bell X-1 which broke the sound barrier, and the Wright brothers' plane near the entrance.
Document 10: Burt Rutan: He has designed 46 aircraft throughout his career, been the co-recipient of the Collier Trophy on two separate occasions, received six honorary doctoral degrees and has won over 100 different awards for aerospace design and development. Rutan has five aircraft on display in the National Air and Space Museum in Washington, D.C., United States: SpaceShipOne, the Virgin Atlantic GlobalFlyer, Voyager, Quickie, and the VariEze.
Document 11: TAPAS-BH-201: TAPAS-BH-201 is a long endurance Unmanned aerial vehicle (UAV) which used to be previously referred as Rustom-II, being developed by India on the lines of the American Predator drones. First flight of the UAV took place in November 2016 after a 3-year delay. It was revealed at that time that the UAV has been renamed from Rustom-II to TAPAS-BH-201, an acronym for Tactical Airborne Platform for Aerial Surveillance-Beyond Horizon-201. Rustom-II was commonly believed to be an Unmanned Combat Aerial Vehicle(UCAV) but at the press conference S Christopher, Director General of DRDO stated "Media reports are incorrect. Tapas is an UAV and not an UCAV."
Document 12: List of aircraft in the Smithsonian Institution: The List of aircraft in the Smithsonian Institution includes aircraft exhibited in the Smithsonian Institution's National Air and Space Museum, Steven F. Udvar-Hazy Center, and the Paul E. Garber Preservation, Restoration, and Storage Facility. The Smithsonian Institution's collection of aircraft and spacecraft is the largest on display in the world.
Document 13: Horten Ho 229: The Horten H.IX, RLM designation Ho 229 (or Gotha Go 229 for extensive re-design work done by Gotha to prepare the aircraft for mass production) was a German prototype fighter/bomber initially designed by Reimar and Walter Horten to be built by Gothaer Waggonfabrik late in World War II. It was the first flying wing to be powered by jet engines.
Document 14: Don R. Berlin: Donovan Reese Berlin (June 13, 1898 – May 17, 1982) was an American military aircraft designer and aircraft industry executive. Among the many designs with which he is associated, are the Curtiss P-36 Hawk, Curtiss P-40 Warhawk and Fisher P-75 Eagle. His name is "synonymous with the development of military aviation". He designed aircraft that were safe, rugged and "a pilot's joy."
Document 15: Stout Bushmaster 2000: The Bushmaster 2000 was a small commuter airliner built in the United States in an attempt to revive the Ford Trimotor design. Work began in 1953 by testing a vintage Trimotor and in 1954 Bill Stout purchased the design rights to the original Trimotor. Due to "Ford Tri-Motor" licensing problems, the Ford 15-AT-D was given the Bushmaster 2000 name. On 15 January 1955, Stout and partner Robert Hayden from the Hayden Aircraft Corporation announced they were planning to build 1,000 new Bushmasters, but it would be eleven years before the first prototype of the new design flew.
