Question: Where did the committee want the Wrights to demonstrate flight?
About the article "Wright Brothers flights of 1909", section "Abstract".

Candidate passages:
The Wrights based the design of their kite and full-size gliders on work done in the 1890s by other aviation pioneers.
They adopted the basic design of the Chanute-Herring biplane hang glider ("double-decker" as the Wrights called it), which flew well in the 1896 experiments near Chicago, and used aeronautical data on lift that Lilienthal had published.
The Wrights designed the wings with camber, a curvature of the top surface.
The brothers did not discover this principle, but took advantage of it.
The better lift of a cambered surface compared to a flat one was first discussed scientifically by Sir George Cayley.
Lilienthal, whose work the Wrights carefully studied, used cambered wings in his gliders, proving in flight the advantage over flat surfaces.
The wooden uprights between the wings of the Wright glider were braced by wires in their own version of Chanute's modified "Pratt truss", a bridge-building design he used for his biplane glider (initially built as a triplane).
The Wrights mounted the horizontal elevator in front of the wings rather than behind, apparently believing this feature would help to avoid, or protect them, from a nosedive and crash like the one that killed Lilienthal.
When Brazilian aviation pioneer Alberto Santos-Dumont flew his "14-bis" in Paris in 1906, French newspapers dubbed the tail-first arrangement a "canard", because of the supposed resemblance to a duck in flight.
Wilbur incorrectly believed a tail was not necessary, and their first two gliders did not have one.
According to some Wright biographers, Wilbur probably did all the gliding until 1902, perhaps to exercise his authority as older brother and to protect Orville from harm as he did not want to have to explain to Bishop Wright if Orville got injured.
(This airfoil caused severe stability problems; the Wrights modified the camber on-site.)
Zahm testified as an aeronautical expert in the 1910-1913 patent lawsuits by the Wright brothers who alleged patent infringement against inventor and manufacturer Glenn Curtiss.
His testimony took over a month.
He testified on behalf of the Curtiss after declining to testify for the Wrights, possibly because the Wrights refused to pay Zahm to appear as an expert witness whereas the Curtiss interests did.
Zahm had been on friendly terms with both sides previously but became a long term adversary of the Wrights during and after the trial.
He worked closely with Glenn Curtiss on the controversial 1914 flying tests of the (substantially rebuilt and modified) Langley Aerodrome in an attempt to show that Langley's machine had been capable of powered flight with a man aboard before the Wrights' glider was.
Zahm testified that earlier experimental gliders and glider designs and publications, before those of the Wrights, had included a variety of monoplane and biplane designs, with horizontal and vertical rudders, and steering concepts of ailerons and wing warping.
There were complex technical issues, notably whether Curtiss's airplanes used a vertical rudder and ailerons in ways that closely matched the patented design of the Wrights.
Experts testified on both sides and sometimes contradicted one another on matters of fact.
In the end judge John R. Hazel ruled in Feb. 1913 for the Wrights, and on appeal a higher court agreed with this decision in 1914. 
Gustave Weißkopf was a German who emigrated to the U.S., where he soon changed his name to Whitehead.
From 1897 to 1915 he designed and built early flying machines and engines.
On August 14, 1901, two and a half years before the Wright Brothers' flight, he claimed to have carried out a controlled, powered flight in his Number 21 monoplane at Fairfield, Connecticut.
The flight was reported in the "Bridgeport Sunday Herald" local newspaper; about 30 years later, several people questioned by a researcher claimed to have seen that or other Whitehead flights.
In March 2013 "Jane's All the World's Aircraft", an authoritative source for contemporary aviation, published an editorial which accepted Whitehead's flight as the first manned, powered, controlled flight of a heavier-than-air craft.
The Smithsonian Institution (custodians of the original Wright Flyer) and many aviation historians continue to maintain that Whitehead did not fly as reported and maintain that the Wrights deserve the honour. 
Roger Lee Wrights (born June 8, 1958) is an American politician, activist and political consultant.
He is the founder, editor, and publisher of the online libertarian newsletter "Liberty For All".
He is the National Vice Chair of the Libertarian National Committee.
Wrights was an unsuccessful contender for the 2012 presidential nomination of the Libertarian Party, finishing as first runner-up to the eventual nominee Gary Johnson.
He was briefly a candidate for Governor of Texas in 2014. 
Wrights was elected National Vice Chair of Libertarian National Committee (LNC) in May 2012.
He previously held that position from 2004 to 2006.
Wrights served as an at-large member of the LNC.
During his time on the LNC, Wrights also served four years on the platform committee.
He is currently a member of the Libertarian Party judicial committee, elected to that body at the 2010 national convention.
Wrights has been active in local, state and national Libertarian Party organizations since 2000 and is a lifetime member of the Libertarian Party.
He has served as secretary and chair of the Libertarian Party of Forsyth County, N.C. and was vice chair of the Libertarian Party of North Carolina (LPNC) for seven years.
He also served as the LPNC ballot access director for two years.
Wrights was formerly the chair of the Burnet County, Texas LP and was the Senate District 24 representative to the Texas LP State Executive Committee.
In 2008, Wrights was campaign manager for the Mary Ruwart for President Committee, and in 2010, he managed Ruwart's campaign for Texas State Comptroller.
Wrights is president of the Foundation for a Free Society, a 501(c)(3) non-profit educational organization dedicated to promoting the principles of liberty, personal sovereignty, private property, and free markets.
