Kite in the context of "Sailing"

A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generates lift), and ornithopters (in which the wings oscillate to generate lift). The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft, and airplanes that use wing morphing are all classified as fixed wing.

Gliding fixed-wing aircraft, including free-flying gliders and tethered kites, can use moving air to gain altitude. Powered fixed-wing aircraft (airplanes) that gain forward thrust from an engine include powered paragliders, powered hang gliders and ground effect vehicles. Most fixed-wing aircraft are operated by a pilot, but some are unmanned or controlled remotely or are completely autonomous (no remote pilot).

Khambhat (/kɑːmˈbɑːt/, Gujarati: [kʰəmbʱɑt] ), also known as Cambay, is a city and the surrounding urban agglomeration in Anand district in the Indian state of Gujarat. It was once an important trading center, but its harbour gradually silted up, and the maritime trade moved to Surat. Khambat lies on an alluvial plain at the north end of the Gulf of Khambhat, noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambat. Khambat is known for its halvasan sweet, sutarfeni, akik stone and kites (patang), and for sources of oil and gas.

Khambat is perhaps the only place in India where the Harappan craft of agate bead making is found in the living tradition. Surprisingly Khambat has no stone deposits; the craft has survived mainly through acquiring stones from the Rajpipla hills, about 200 km away from the city. In the folklore of Khambat, the beginning of the craft is attributed to Baba Ghor, a 1500 AD saint from Ethiopia (Habash) who had led a large contingent of Muslims (Siddi) to settle in the city. However, in the archaeological record the origin of the craft can be traced to nearby Lothal, a Harappan outpost that flourished about 4000 years ago.

The history of aerial warfare began in ancient times, with the use of kites in China. In the third century, it progressed to balloon warfare. Airplanes were put to use for war starting in 1911, initially for reconnaissance, and then for aerial combat to shoot down the recon planes. The use of planes for strategic bombing emerged during World War II. Also during World War II, Nazi Germany developed many missile and precision-guided munition systems, including the first cruise missile, the first short-range ballistic missile, the first guided surface-to-air missiles, and the first anti-ship missiles. Ballistic missiles became of key importance during the Cold War, were armed with nuclear warheads, and were stockpiled by the superpowers – the United States and the Soviet Union – to deter each other from using them.

Unpowered aircraft can remain airborne for a significant period of time without onboard propulsion. They can be classified as gliders, lighter-than-air balloons and tethered kites. In the case of kites, lift is obtained by tethering to a fixed or moving object, perhaps another kite, to obtain a flow of wind over the lifting surfaces. In the case of balloons, lift is obtained through inherent buoyancy and the balloon may or may not be tethered. Free balloon flight has little directional control. Gliding aircraft include sailplanes, hang gliders, and paragliders that have full directional control in free flight.

The history of aviation spans over two millennia, from the earliest innovations like kites and attempts at tower jumping to supersonic and hypersonic flight in powered, heavier-than-air jet aircraft. Kite flying in China, dating back several hundred years BC, is considered the earliest example of man-made flight. In the 15th-century Leonardo da Vinci designed several flying machines incorporating aeronautical concepts, but they were unworkable due to the limitations of contemporary knowledge.

In the late 18th century, the Montgolfier brothers invented the hot-air balloon which soon led to manned flights. At almost the same time, the discovery of hydrogen gas led to the invention of the hydrogen balloon. Various theories in mechanics by physicists during the same period, such as fluid dynamics and Newton's laws of motion, led to the development of modern aerodynamics; most notably by Sir George Cayley. Balloons, both free-flying and tethered, began to be used for military purposes from the end of the 18th century, with France establishing balloon companies during the French Revolution.

The Wright brothers designed, built and flew a series of three manned gliders in 1900–1902 as they worked towards achieving powered flight. They also made preliminary tests with a kite in 1899. In 1911 Orville conducted tests with a much more sophisticated glider. Neither the kite nor any of the gliders were preserved, but replicas of all have been built.
