As the boys grew older, they continued to tinker and invent various items. An outright purchase was not possible, however.
Nevertheless, the Army extended the date for successful completion of the tests to June 28, Some aviation historians believe that applying the system of three-axis flight control on the glider was equal to, or even more significant, than the addition of power to the Flyer. Due to a horrible accident, he was laid up for a lengthy period and was unable to begin his university career.
The absence of newsmen also reduced the chance of competitors learning their methods. But when the Board asked if the price included exclusive use of their design, the Wrights said that their contract with Flint and Company precluded such an agreement, and the communications ended.
Wilbur's speech was the first public account of the brothers' experiments. Styles said that she was forming an inter-agency group to resolve the differences among agencies regarding the requirements for a contract to qualify as performance-based.
The longest flight on September 9 lasted one hour and two minutes, but Orville carried no passenger.
Back 11 Chandler and Lahm, pp. Long-term, complex operations and support services often do not produce any material, durable artifact that is adequate evidence of the quality of contract performance, and many important service outcomes defy attempts at clear, specific, objective and measurable description and are assessable only subjectively.
After successful ventures in running a print shop, publishing a newspaper and operating a bike shop, the brothers developed a glider.
With this knowledge, and a more accurate Smeaton number, the Wrights designed their glider. Once bitten and now twice shy, the War Department was interested only in what today we would call a commercial or a nondevelopmental item.

Referring to your letter of the 21st instant to the Honorable Secretary of War inviting attention to the experiments in mechanical flight conducted by Messrs. The Wrights took hundreds of pictures of their experiments and they measured everything.
Lahma lieutenant in the U. Wright be informed that the Board does not care to formulate any requirements for the performance of a flying machine or take any further action on the subject until a machine is produced which by actual operation is shown to be able to produce horizontal flight and to carry an operator.
