Actually, Augustus Moore Herring was quite a pioneer during the very earliest days of heavier-than-air flight. |
|
The Pacific and North Atlantic had never been fully crossed by heavier-than-air craft. |
|
They are also reminiscent of the 19th century scientists who claimed that heavier-than-air flying machines were impossible. |
|
Americans were the first to take weapons into the air in heavier-than-air flying machines. |
|
In 1886, he designed a steam-powered aircraft, and in 1896 became the first to build heavier-than-air machines capable of sustained flight. |
|
For the most part, this technology culture appeared at the same time as the air service itself, due to the nature of heavier-than-air flight. |
|
Unpowered manned heavier-than-air vehicles must be launched to obtain lift. |
|
Gliding, also called soaring, flight in an unpowered heavier-than-air craft. |
|
The Wrights were not the first to pilot a heavier-than-air craft. |
|
Sometime before the Wright brothers' momentous flights of December 17, 1903, Quick began construction of a heavier-than-air flying machine of unknown configuration. |
|
The Wright brothers showed that heavier-than-air flight was possible, but that did not entitle them to a monopoly of heavier-than-air flying machines. |
|
Wilbur and Orville Wright made the first successful flight of a heavier-than-air, mechanically driven airplane. |
|
Simple heavier-than-air craft include kites. |
|
Aviation, the development and operation of heavier-than-air aircraft. |
|
This clear analysis the clearest possible statement of the problem of heavier-than-air flight became the basis for the Wright brothers' work over the next half decade. |
|
History of flight, development of heavier-than-air flying machines. |
|
Available in single and dual stage options, the precleaners work during the first stage of an air intake system to prevent heavier-than-air particles from entering the system, ensuring maximum engine performance. |
|
Some writers, indeed, have suggested that it impeded the development of heavier-than-air aviation in that it discouraged the search for alternative ways to fly. |
|
A heavier-than-air aircraft supported in flight chiefly by the reactions of the air on one or more power driven rotors on substantially vertical axes. |
|
The ventilation pattern must remove the heavier-than-air solvent vapors from the lower levels of the workspaces and should be sufficient to keep total vapor concentration below the exposure limits. |
|
|
In 1849 he launched a full-sized glider which carried a ten-year-old boy off the ground for several yards in the first documented heavier-than-air human flight. |
|
It is an apt commemoration of the Wright Brothers' remarkable launch of the first heavier-than-air, self-propelled flying machine. |
|
The stamp marks the 100th anniversary of the first controlled, powered, sustained flight in a heavier-than-air flying machine. |
|
And folks laughed at Santos Dumont, at the Wrights, and at all the other fellows, who said they could take a heavier-than-air machine, and skim above the clouds like a bird. |
|
Orville Wright passes away in the United States of America. He was one of the two brothers who, for the first time, flew a heavier-than-air apparatus built by themselves. |
