Question: When did the Wright brothers fly at Kitty Hawk?
About the article "Wright Brothers flights of 1909", section "Abstract".

Candidate passages:
Kitty Hawk became famous after the Wright brothers of Dayton, Ohio, made the first controlled powered airplane flights at the Kill Devil Hills, four miles (6 km) south of the town, on December 17, 1903.
After the flights, the brothers walked back to Kitty Hawk, where they sent a telegram from the Weather Bureau office to their father informing him of their success.
Kitty Hawk is often mistakenly credited as the site of the powered flights.
The Wrights chose the area because its frequent winds and soft sandy surfaces were suitable for their glider experiments, which they conducted over a three-year period prior to making the powered flights.
The aircraft carrier USS "Kitty Hawk" (CV-63), the B-2 Spirit stealth bomber AV-19 with an aircraft number of 93-1086, the aircraft transport ship USS "Kitty Hawk" (AKV-1), and the Apollo 14 command module have been named for the town, which incorporated in 1981. 
Crossfield was played by Scott Wilson in the 1983 film "The Right Stuff".
Crossfield co-authored "Always Another Dawn", a story of a rocket test pilot, with Clay Blair Jr, and authored "Onward and Upward" "Research Airplanes, Act II".
In 1986 he created and funded the A. Scott Crossfield Aerospace Education Teacher of the Year Award presented annually under the stewardship of the Civil Air Patrol during the National Congress on Aerospace Education now called the National Conference on Aerospace Education (NCASE).
After his death in 2006 and the shift of NCASE from an annual to biannual conference, Crossfields's daughter, Sally Crossfield Farley, moved the award to the National Aviation Hall of Fame and it is now presented during the Enshrinement Weekend each July in Dayton, Ohio.
From 2001 to 2003, Crossfield trained pilots Terry Queijo, Kevin Kochersberger, Chris Johnson and Ken Hyde for The Wright Experience, which prepared to fly a reproduction Wright Flyer on the 100th anniversary of the Wright Brothers' first flight on December 17, 1903.
The training was successful, but the re-creation of the flight on December 17, 2003 was ultimately not successful due to low engine power and the flyer's rain-soaked fabric covering which added considerably to its takeoff weight.
The Wright replica did fly successfully at Kitty Hawk after the Centennial jubilee but without media coverage.
In one sense, it was only fitting that Crossfield conducted this experimental flight training because all pilots in this project had to unlearn their considerable flying experience and learn forgotten Wright brothers techniques.
When asked to name his favorite airplane, Crossfield replied, "the one I was flying at the time," because he thoroughly enjoyed them all and their unique personalities.
To young teens, he would compare airplanes to different girls or boys they would date: each one was special and a learning experience.

USS "Kitty Hawk" (APV-1/AKV-1), formerly SS "Seatrain New York", was built in 1932 by Sun Shipbuilding & Drydock Corporation of Chester, Pennsylvania for Seatrain Lines, Inc. She was acquired by the United States Navy on 25 June 1941; and renamed "Kitty Hawk" on 8 July.
She was named after Kitty Hawk, North Carolina where the Wright brothers made the world's first powered heavier than air flight on 17 December 1903.
She was converted to an aircraft transport by Tietjin & Land Dry Dock Corporation, Hoboken, New Jersey and commissioned on 26 November 1941, at New York Navy Yard, with Commander E. C. Rogers in command.
