Early flying machines include all forms of aircraft studied or constructed before the development of the modern aeroplane by 1910. The story of modern flight begins more than a century before the first successful manned aeroplane, and the earliest aircraft thousands of years before. In the 1st century AD Chinese Emperor Wang Mang recruited a specialist scout to be bound with bird feathers; he is claimed to have glided about 100 meters. In 559 AD, Yuan Huangtou is said to have landed safely following an enforced tower jump. In medieval Europe the earliest recorded tower jump dates from 852 AD, when Armen Firman made a jump in Cordoba, Spain, reportedly covering his body with vulture feathers and attaching two wings to his arms; on landing he is said to have crashed and sustained a back injury which some critics attributed to a lack of a tail. In 1010 AD English monk Eilmer of Malmesbury flew from the tower of Malmesbury Abbey in a primitive glider. Eilmer was said to have flown over 200 yards (180 m) before landing, breaking both his legs.

Eilmer later remarked that the only reason he did not fly further was that he forgot to give his machine a tail. This burst of activity was followed by a lull of several centuries. Jumping revived in 1496 with Seccio breaking both arms in Nuremberg. In 1507 John Damian strapped on wings covered with chicken feathers and jumped from the walls of Stirling Castle in Scotland, breaking his thigh, later blaming it on not using eagle feathers.

Similar attempts continued until the early 19th century, with never more than partial success. Download Free Software Popol Vuh Heart Of Glass Rarity there. Francis Willughby's suggestion, published in 1676, that human legs were more comparable to birds' wings in strength than arms, had only occasional influence. As late as 1811, Albrecht Berblinger constructed an ornithopter and jumped into the Danube at Ulm.

From ancient times the Chinese have understood that hot air rises and have applied the principle to a type of small hot air balloon called a sky lantern. A sky lantern consists of a paper balloon under or just inside which a small lamp is placed. Sky lanterns are traditionally launched for pleasure and during festivals. According to Joseph Needham, such lanterns were known in China from the 3rd century BC. Their military use is attributed to the general Zhuge Liang, who is said to have used them to scare the enemy troops. The modern era of lighter-than-air flight began early in the 17th century with Galileo's experiments in which he showed that air has weight. Fsb Overclock Program Intel there. Around 1650, Cyrano de Bergerac wrote some fantasy novels in which he described the principle of ascent using a substance (dew) he supposed to be lighter than air, and descending by releasing a controlled amount of the substance.[19] Francesco Lana de Terzi measured the pressure of air at sea level and in 1670 proposed the first scientifically credible lifting medium in the form of hollow metal spheres from which all the air had been pumped out.

These would be lighter than the displaced air and able to lift an airship. His proposed methods of controlling height are still in use today; by carrying ballast which may be dropped overboard to gain height, and by venting the lifting containers to lose height.[25] In practice de Terzi's spheres would have collapsed under air pressure, and further developments had to wait for more practicable lifting gases.
