Question: Wing warping, a system for lateral aircraft control, was pioneered by the Wright brothers during their first controlled, sustained flight near which now-famous location?

Context paragraphs:
Abramovich Flyer: The Abramovich Flyer was an early aircraft built by Russian aviator Vsevolod Mikhailovich Abramovich in 1912, based on the Wright brothers' designs he had seen while working for their German subsidiary.  Differences from the Wright designs of the time included wheeled undercarriage and conventional empennage replacing the canard the Wrights used.  Abramovich retained the wing warping technique the Wrights used for banking the aircraft, but controlled this with a control stick rather than the hip-controlled harness of the Wrights' design.  Using this aircraft, Abramovich was successful in setting many early aviation records in Russia, including carrying several passengers.

Blériot VIII: The Blériot VIII was a French pioneer era aeroplane built by Louis Blériot, significant for its adoption of both a configuration and a control system that were to set a standard for decades to come.  The previous year, Blériot had experimented with a tandem wing design, the Blériot VI, then built another aircraft, the Blériot VII, in which the rear wing was somewhat smaller than the front wing.  In the Blériot VIII, he reduced the size of the rear wing yet again, to the point where it was no longer contributing much in the way of lift, but had become the horizontal stabiliser.  More novel was his adoption of a single control stick that would control both roll and pitch, while the rudder was controlled by a horizontal, centrally pivoted bar swung by the pilot's feet.  A similar control arrangement for roll and pitch control had been incorporated into an aircraft the previous year by Robert Esnault-Pelterie, but the Bleriot VIII was the first use in a single airframe of the combination of hand/arm-operated joystick and foot-operated rudder control, that is in use to the present day, for the basic format of aerodynamic aircraft control systems.

Fokker A.I: The Fokker A.I (Fokker designation M.8) was an "A-class" unarmed two-seat monoplane observation aircraft of the 1914-15 era early in World War I, powered as the earlier Fokker M.5 was, by a 58.8 kW (80 PS) Oberursel U.0 seven cylinder rotary engine, or "umlaufmotor", a near-clone of the Gnome Lambda rotary engine of the same power output level — the same U.0 seven cylinder rotary engine version was used on all Fokker military monoplanes before the Fokker E.II "Eindecker" fighter's debut in 1915-16.  The A.I aircraft resembled a substantially enlarged Fokker M.5, with a tall dorsal cabane structure to handle the triple sets of stationary flying and landing wires anchored to the wing panels' forward spar, each panel having fourteen wing ribs, and the similarly triple sets of wing warping cables attached to the rear spar.  The A.I and earlier A.IIs were both built by Fokker and license-built by Halberstadt.  The origins of the A.I, A.II and A.III were in a Morane-Saulnier Type H purchased from France.  This led to the initial Fokker M.5 airframe designed by Martin Kreutzer, from which the larger A.I was derived.  Fokker gave many aerobatic demonstrations in the M.5 on the eve of World War I.  The M.8, was ordered as the A.I by the "Fliegertruppe" (Imperial German Army Air Service) and between Fokker and Halberstadt, about 63 were produced.

REP Type N: The REP Type N was a military reconnaissance aircraft produced in France in 1914.  It was a wire-braced, mid-wing monoplane of conventional design with fixed, tailskid undercarriage.  The fuselage was constructed of steel tube and was of triangular cross-section, with the apex on the ventral side.  The pilot and observer sat in tandem, open cockpits.  Lateral control was by wing warping.

Wing warping: Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft.  The technique, used and patented by the Wright brothers, consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions.  In many respects, this approach is similar to that used to trim the performance of a paper airplane by curling the paper at the back of its wings.

Question Mark (aircraft): Question Mark (""?"")  was a modified Atlantic-Fokker C-2A transport airplane of the United States Army Air Corps.  In 1929, commanded by Major Carl A. Spaatz, it was flown for a flight endurance record as part of an experiment with aerial refueling.  "Question Mark" established new world records in aviation for sustained flight (heavier-than-air), refueled flight, sustained flight (lighter-than-air), and distance between January 1 and January 7, 1929, in a non-stop flight of more than 150 hours near Los Angeles, California.

Wright brothers patent war: The Wright brothers patent war centers on the patent they received for their method of an airplane's flight control.  The Wright brothers were two Americans who are widely credited with inventing and building the world's first flyable airplane and making the first controlled, powered and sustained heavier-than-air human flight on December 17, 1903.

Morane-Saulnier L: The Morane-Saulnier L, also known as the Morane-Saulnier Type L was a French parasol wing one or two-seat scout aeroplane of the First World War.  The Type L became one of the first successful fighter aircraft when it was fitted with a single machine gun that fired through the arc of the propeller, which was protected by armoured deflector wedges.  Its immediate effectiveness in this role launched an arms race in fighter development, and the Type L was swiftly rendered obsolete.  The original Type L used wing warping for lateral control, but a later version designated Type LA was fitted with ailerons.

Wright Flyer: The Wright Flyer (often retrospectively referred to as Flyer I or 1903 Flyer) was the first successful heavier-than-air powered aircraft.  It was designed and built by the Wright brothers.  They flew it four times on December 17, 1903, near Kill Devil Hills, about four miles south of Kitty Hawk, North Carolina, US.  Today, the airplane is exhibited in the National Air and Space Museum in Washington D.C. The U.S. Smithsonian Institution describes the aircraft as "the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard".  The flight of "Flyer I" marks the beginning of the "pioneer era" of aviation.

Wright brothers: The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane.  They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina.  In 1904–05 the brothers developed their flying machine into the first practical fixed-wing aircraft.  Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
