The crash involving Welsh was found by the Army's board of inquiry to have been pilot error by Welsh, who had intentionally placed the aircraft 45 degrees nose down prior to the test to build momentum. Deliveries of the plane continued, although the statement of one eyewitness led to speculation that the elevator had not responded to inputs to pull out of the dive. |

The Model Cs quickly earned an unenviable reputation when six of the eight passing their acceptance flights crashed between July 8, 1913, and February 9, 1914, with all but one of the crashes involving fatalities. The fifth crash on November 24, 1913, killed the Army's chief instructor and a new pilot. As a result, the Wright Company factory manager, [[Grover Loening]], concluded that the Wright C was flawed by a design defect. [[Orville Wright]] disagreed, maintaining that pilot error was to blame, specifically unfamiliarity with the more powerful engine. He theorized that pilots stalled the aircraft by applying full power that in level flight made [[angle of attack]] critical. He proposed that full power be used only to climb and invented an angle-of-incidence indicator sensitive enough to warn a pilot that his climb or dive was too steep. He also completed work on an [[autopilot]] which he patented in October 1913, and successfully demonstrated in December, but a [[autopilot#First autopilots|gyroscope-operated autopilot]] patented by [[Lawrence Sperry]] proved more immediately practical and became standard. |

The Wright Model C "Speed Scout" was an early military aircraft produced in the United States and which first flew in 1912. It was a development of the Model B but was specifically designed to offer the Aeronautical Division, U.S. Signal Corps a long-range scouting aircraft.
It featured a more powerful engine over the Wright B, and an endurance of around four hours. Still a two-seater, it added a complete second set of controls, meaning that either crew member could operate the aircraft. On some, the lever controls were replaced with two wheels mounted on a single yoke.[1] Aerodynamically, the small finlets ("blinkers" in the Wrights' terminology) that had been used on the Model B's undercarriage were replaced by two vertical vanes attached to the forward end of the skids.
The aircraft had a short service life, from 1912 to 1914, because of a series of fatal crashes that destroyed six of the eight aircraft manufactured for the Army.
The increase in power was to meet Army specifications that the aircraft have a rate of climb of 200 feet per minute (1 m/s), a fuel capacity for a four-hour flight, and carry a weight of 450 pounds including crew. Its simplified twin-lever control system was confusing to operate and proved difficult for novice pilots to master, while the plane itself was tail heavy and unstable.
Seven Model Cs were used by the Aeronautical Division: S.C. 10-14, S.C. 16, and S.C. 5, a Burgess Model F rebuilt to Wright C standards. Five new Wright Scouts were delivered to the Aviation School at College Park, Maryland; one to the provisional 1st Aero SquadronatTexas City, Texas; and the last shipped to the Philippines. An eighth Aircraft (S.C. 18), a Burgess Model J delivered in January 1913, was a Wright C built under license by the Burgess Company and Curtis.
