The June Bug was an American "pioneer era" biplane built by the Aerial Experiment Association (A.E.A) in 1908 and flown by Glenn Hammond Curtiss. The aircraft was the first American airplane to fly at least 1km in front of a crowd.
A Scientific American competition in 1907 offered a solid silver sculpted trophy, and $25,000 in cash, to be awarded to whoever made the first public flight of over 1 kilometer (3,280 ft) in an American aircraft. In 1907, Glenn Curtiss and the Aerial Experiment Association began building the June Bug with hopes of winning the Scientific American Cup.
The June Bug, also referred to as Aerodrome #3 (the third powered airplane built by the A.E.A), included the previously used aileron steering system, but a shoulder yoke made it possible for the pilot to steer by leaning from side to side. The aircraft featured a canard, horizontal surfaces, and a rear rudder. The original varnish sealing the wing fabric cracked in the heat, so a mixture of turpentine, paraffin, and gasoline was used on the aircraft instead. The June Bug had yellow wings due to the yellow ochre added to the wing mixture in order to make the aircraft show up better in the orthochromic-form monochrome photographs of the time.
The aircraft was named by Alexander Graham Bell after the common Phyllophaga , [1] a beetle known colloquially in North America as the "June bug". This was because June bugs were observed to fly similarly to aircraft: they have large stiff outer wings for gliding, and more delicate smaller propeller-like wings that do the actual propulsion.
The June Bug was tested by G.H. Curtiss in Hammondsport, New York, at Stony Brook Farm, on June 21, 1908. Three of the four test flights were successful, with distances of 456 ft (139 m), 417 ft (127 m), and 1,266 ft (386 m), at an average speed of 34.5 mph (55.5 km/h). On June 25, performances of 2,175 ft (663 m) and 3,420 ft (1,040 m) were considered encouraging, and the A.E.A. contacted the Aero Club of America to sign up for the Scientific American Cup.
The Aero Club contacted the Wright brothers, offering them the chance to make an attempt first. Orville wrote to decline the opportunity on June 30, as the Wrights were busy completing their deal with the United States government. Orville's message was received by July 1, and G.H. Curtiss took to the air as requested on July 4 (Independence Day).
The flight was made a public event, and spectators were allowed to watch. The event was overseen by a delegation of 22 members of the Aero Club, headed by Alan R. Hawley. The Kalem Company's film crew covered the event, making the June Bug the first airplane in the United States to perform in a movie. The nearby Pleasant Valley Wine Company opened its doors and offered free samples to the spectators at the event. Charles M. Manly, who had unsuccessfully tested the Langley Aerodrome in 1903, measured out the 1 km and 20 ft (6.1 m) distance with volunteer help. The June Bug took one false start, going 40 feet (12 m) high, but not far enough. On the second try, the airplane successfully flew 5,085 ft (1550 m) in 1 minute 42 seconds, winning the trophy and a US$25,000 cash prize.
Amidst the publicity following the flight, the Wrights sent a warning to Curtiss that they had not given permission for the use of "their" aircraft control system to be used "for exhibitions or in a commercial way". In fact, none of the A.E.A.'s aircraft used a wing-warping system like the Wrights' for control, relying instead on triangular ailerons designed by Alexander Graham Bell, which he successfully patented in December 1911. However, in 1913 a court ruled that this technique was an infringement of the Wright's 1906 patent.
Three years previous to the June Bug's flight, the Wrights had made flights of up to 24 miles (38 km) without official witnesses. However, the Wrights would have been required to install wheels and dispense with a catapult launch to compete for the 1908 prize.
From October to November, the June Bug was modified by adding floats to it in an attempt to create a seaplane. Renamed Loon, attempts to fly it began on Keuka Lake on November 28. Although the aircraft could achieve speeds of up to 29 mph (47 km/h) on the water, it could not take off, and on January 2, 1909, one of the floats filled with water, causing the Loon to sink. It was recovered, but rotted in a nearby boathouse.
A replica of the June Bug was built and flown in 1976 by Mercury Aircraft of Hammondsport. [2]

The Wright brothers, Orville Wright and Wilbur Wright, were American aviation pioneers generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of an engine-powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, four miles south of Kitty Hawk, North Carolina, at what is now known as Kill Devil Hills. In 1904 the Wright brothers developed the Wright Flyer II, which made longer-duration flights including the first circle, followed in 1905 by the first truly practical fixed-wing aircraft, the Wright Flyer III.
An aileron is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll, which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'.
Glenn Hammond Curtiss was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines.
Curtiss Aeroplane and Motor Company was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation.
Thomas Etholen Selfridge was a first lieutenant in the U.S. Army and the first person to die in an airplane crash. He was also the first active-duty member of the U.S. military to die in a crash while on duty. He was killed while seated as a passenger in a Wright Flyer, on a demonstration flight piloted by Orville Wright.
The Silver Dart was a derivative of an early aircraft built by a Canadian/U.S. team, which after many successful flights in Hammondsport, New York, earlier in 1908, was dismantled and shipped to Baddeck, Nova Scotia. It was flown from the ice of Baddeck Bay, a sub-basin of Bras d'Or Lake, on 23 February 1909, making it the first controlled powered flight in Canada. The aircraft was piloted by one of its designers, Douglas McCurdy. The original Silver Dart was designed and built by the Aerial Experiment Association (AEA), which had been formed under the guidance of Dr. Alexander Graham Bell.
The Aerial Experiment Association (AEA) was a Canadian-American aeronautical research group formed on 30 September 1907, under the leadership of Dr. Alexander Graham Bell.

The Red Wing was an early aircraft designed by Thomas Selfridge and built by the Aerial Experiment Association in 1908. It was named for the bright red color of its silk wings - chosen to achieve the best result with the photographic materials and techniques of the day.
The White Wing was an early US aircraft designed by Frederick W. Baldwin and built by the Aerial Experiment Association in 1908. Unusual for aircraft of its day, it featured a wheeled undercarriage. The wings were equipped with ailerons controlled by a harness worn around the pilot's body; leaning in one direction would cause the aircraft to bank to follow. The ailerons led to a legal dispute with the Wright brothers over the brothers' patent on movable wing surfaces.
The Wright Flyer made the first sustained flight by a manned heavier-than-air powered and controlled aircraft—an airplane—on December 17, 1903. Invented and flown by brothers Orville and Wilbur Wright, it marked the beginning of the pioneer era of aviation.
The 1911 Curtiss Model D was an early United States pusher aircraft with the engine and propeller behind the pilot's seat. It was among the first aircraft in the world to be built in any quantity, during an era of trial-and-error development and equally important parallel technical development in internal combustion engine technologies.
Frederick Walker Baldwin, also known as Casey Baldwin, paternal grandson of Canadian reform leader Robert Baldwin, was a hydrofoil and aviation pioneer and partner of the famous inventor Alexander Graham Bell. He was manager of Graham Bell Laboratories from 1909–32, and represented Victoria in the Nova Scotia Legislature from 1933–37, where he was instrumental in bringing about the creation of Cape Breton Highlands National Park. In 1908, he became the first Canadian and British subject to fly an airplane.
The Curtiss No. 1 also known as the Curtiss Gold Bug or Curtiss Golden Flyer was a 1900s American early experimental aircraft, the first independent aircraft designed and built by Glenn Curtiss.
The Curtiss Model E was an early aircraft developed by Glenn Curtiss in the United States in 1911.
The Curtiss No. 2, often known as the Reims Racer, was a racing aircraft built in the United States by Glenn Curtiss in 1909 to contest the Gordon Bennett Cup air race in Reims, France that year.
The Santos-Dumont Demoiselle was a series of aircraft built in France by the Brazilian aviation pioneer Alberto Santos-Dumont. They were light-weight monoplanes with a wire-braced wing mounted above an open-framework fuselage built from bamboo. The pilot's seat was below the wing and between the main wheels of the undercarriage. The rear end of the boom carried a tailwheel and a cruciform tail. The name is a contraction of mademoiselle and is a synonym for "jeune fille"—young girl or woman—but also the common name in French for a Damselfly.
The Wright brothers patent war centers on the patent that the Wright brothers received for their method of airplane flight control. They 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.
Several aviators have been claimed to be the first to fly a powered aeroplane. Much controversy surrounds these claims. It is generally accepted today that the Wright brothers were the first to achieve sustained and controlled powered manned flight, in 1903. It is popularly held in Brazil that their native citizen Alberto Santos-Dumont was the first successful aviator, discounting the Wright brothers' claim because their Flyer took off from a rail, and in later flights would sometimes employ a catapult. An editorial in the 2013 edition of Jane's All the World's Aircraft supported the claim of Gustave Whitehead. Claims by, or on behalf of, other pioneers such as Clement Ader have also been put forward from time to time.
