The four stages of human flight history are
The history of human flight could be divided into the following four stages: 1. [The exploration period of flight (before the 20th century): During this period, humans began to explore flight, such as the success of balloon flight and the rise of airships. At the same time, they also explored and tested aircraft.] For example, in 1783, the balloons designed by the French brothers Joseph Michels and Jacques Mongofié successfully flew over Paris in two months, and ten days later, the hydrogen balloons of their competitors, Jacques Alexandre Charles and Nicholas Louis Robert, flew 25 miles and stayed in the air for more than two hours. In 1809 - 1810, the British philosopher Sir George Kelly published "On Air Navigation", which determined the four forces of flight (gravity, lift, drag, and thrust); Leonardo da Vinci's "Principles of Bird Flight" also laid the early foundation for aviation development. 2. ** The piston-engine aircraft period (early 20th century to the mid-40s)**: During this period, aircraft flight became a reality and gradually developed. On December 17, 1903, the Wright brothers successfully flew into the blue sky after four test flights. This was a major breakthrough in the history of human flight, even though the longest flight time was only 15 seconds and the flight distance was 66 meters. 3. ** From the beginning of the use of powered aircraft in 1914 to the subsequent development stage **: Since 1914, humans began to use powered aircraft. With the outbreak of the First World War, aircraft were used in war and their prospects were constantly changing. During this period, large-scale industrial production of aircraft related equipment, such as the Ispano-Suza engine, etc. 4. ** Modern Stage (From supersonic jet to modern development)**: Including the development of modern aviation technology, such as the emergence of supersonic jet, the commercial aviation industry has greatly changed the concept of distance in the world, and military aircraft has also become an important tool that affects the outcome of war. At the same time, it also included the research and development of modern personal aircraft. For example, in the 1950s, the United States began to study personal aircraft. Later countries also continued to carry out related research and development, but they faced problems such as endurance, load, noise, safety, cost, etc. However, they continued to develop as technology advanced.

The Three Stages of Human Flight
Human flight activities were generally divided into three stages: aviation, aerospace, and aerospace. Flight referred to flight activities in the atmosphere. Usually, flights below 100 kilometers were considered aviation activities. They mainly used an air-breathing engine that only carried a combustion agent. It relied on inhaling air to burn to output power. Space flight was a flight activity that flew out of the atmosphere and into the solar system. Flight activities above 100 kilometers were called space activities. Space flight required the use of combustion agents and oxidisers to complete the combustion and output power. Space travel, on the other hand, was to fly out of the solar system and travel to the vast universe. The novel " Hundred Years of Spaceship " is equally exciting.

What are the four stages of flight?
Different flight missions had different flight phases. The following were the phases of several common flight missions: - ** Airplane Civil Flight **: Including Taxiing Stage (Taxiing from the apron to the runway may require a guide car when the weather is bad. Large passenger planes can be assisted by cameras, while small and medium-sized passenger planes rely more on pilot experience. After arriving at the destination, taxi from the runway to the parking space), take-off stage (release the brake from the runway end to leave the ground to reach the specified height, pay attention to the take-off decision speed, wheel lifting speed, take-off safety speed, etc.), flight stage (during flight, you must abide by relevant regulations, such as turning on the flight mode, etc.), landing stage (facing the influence of weather and crosswinds, although there is an automatic landing system, the captain also needs to skillfully control the aircraft to correct the impact and land along the runway center line). - Chang'e-5 Flight: Launch into orbit, Earth-Moon transfer, near-moon braking, lunar flight, landing and descent, lunar surface work, lunar surface ascent, rendezvous, docking and sample transfer, lunar waiting, lunar transfer, and re-entry recovery. - [Chang'e-6 Flight]: Launch into orbit, Earth-Moon transfer, near-moon braking, lunar orbit, landing, lunar surface, lunar surface ascent, rendezvous, docking, sample transfer, lunar orbit, lunar transfer, re-entry and return. - ** China's Manned Space Flight (Take Shenzhou as an example)**: The first stage is the single-ship flight test stage, such as the basic design test of Shenzhou V's manned spacecraft, the multi-person and multi-day in-orbit flight test of Shenzhou VI, and the first spacewalk of Shenzhou VII. The second phase was jointly carried out by the Shenzhou spacecraft and the Tiangong Experimental Space Station. For example, Shenzhou 8 completed the space rendezvous, docking, and separation experiments with Tiangong 1, and Shenzhou 9 sent female astronauts into space and accurately docked with Tiangong.

Four Stages of Flight Prep
Flight preparation included four stages: flight preparation, flight preparation, flight implementation, and flight evaluation. Flight preparation was usually completed on the first day or before the flight mission. It required sufficient preparation, predicting various complicated situations that might occur, and drafting flight dispatch plans. Flight preparation was based on flight preparation. It included studying the weather conditions, checking the flight preparation and ground support work before the flight, and deciding to release the aircraft. Flight implementation was the actual flight operation process. Flight commentary was a summary and evaluation of the entire flight process.

The History of Human Flight
The history of human flight was a history full of dreams, exploration, and innovation. In ancient times, flying mainly existed in legends. In ancient Egypt, there was a legend of the goddess Isis soaring in the sky to protect her subjects. In ancient Greece, Daedalus and his son Icarus made wings of feathers and wax to fly across the Aegean Sea. In China, kites could be the prototype of man-made airplanes. Legend has it that they were invented by Mozi and improved by Lu Ban. The ancient wooden kite was used for communication and detective in war, and could even carry gunpowder to attack. The sky lantern (Kongming Lantern) was said to have been invented by Zhuge Liang. The principle was the same as that of hot air balloons. In ancient times, it was used for military signals, and in modern times, it was used for blessing. In ancient times, there were also flying people who tried to fly. Although most of them failed, they took the first step in human flight exploration. After the 17th century, Da Vinci's research on the ornithopter was a major advancement in the history of aviation. He left behind many manuscripts and sketches based on the observation of birds. However, the practical ornithopter was not actually manufactured, but gliders were derived from experiments. Otto Lilindahl was an important pioneer in glider research. He flew fixed-wing gliders many times. In 1783, the Mongolfei brothers made the world's first manned hot air balloon flight, which lasted 25 minutes. In 1896, the American inventor Samuel Pierpont Langley conducted a successful test flight of the unmanned aircraft model "space station." This was the first time that an aircraft with a gravity greater than air flew continuously. In 1900, the world's first airship, the Zeppelin LZ1, flew in Germany. In 1903, the Wright brothers successfully tested the "Flyer One", which was the first powered, manned, sustained, stable, and controllable biplane in human history. In 1909, the Frenchman Blelio flew across the English Channel for the first time in a single-wing plane. In 1919, Hugo Junkers of Germany successfully tested the world's first all-metal passenger plane, Junkers F.13. There were many innovative aspects in the design of the aircraft. In 1927, the American pilot, Lindberg, completed the first solo trans-Atlantic flight. In 1930, Frank Whitt of the United Kingdom obtained a patent for a gas turbine engine. In 1933, the American Lin Bai flew across the Atlantic Ocean for the first time without landing. In 1939, Germany successfully tested the first jet He178 single-wing aircraft. In the same year, Igor Sikowski's VS - 300 helicopter made its first successful flight. This was the world's first truly practical helicopter. In 1947, test pilot Charles Yaeger flew the X - 1 aircraft for the first time to break the sound barrier. In modern times, various countries were still researching personal flying devices. Although they had achieved some results, they still faced many challenges in terms of endurance, load, noise, safety, and cost. However, with the continuous advancement of science and technology, the development prospects of human flight were still broad. The novel "Hundred Years of Spaceship" is equally exciting.

The History of Human Flight
The development process of human flight history can be traced back to the early attempts. In the early days, humans could only observe birds flying in the sky and dreamed of being able to fly like them. With the development of science and technology, the Wright brothers made a great breakthrough in 1903. They successfully invented and flew the first powered airplane, which marked the beginning of the modern aviation era. Subsequently, airplanes continuously evolved in terms of design, power, and performance. During World War I and World War II, the military needs promoted the rapid development of aviation technology. After the wars, commercial aviation gradually emerged. Airlines were established, and airplanes became important means of transportation for people to travel long distances. In addition to airplanes, the development of helicopters also provided vertical take - off and landing capabilities, which were widely used in various fields such as rescue and short - distance transportation. In modern times, with the continuous progress of materials science, aerodynamics, and propulsion technology, new flight technologies such as supersonic flight and unmanned aerial vehicles (UAVs) have emerged, constantly expanding the boundaries of human flight.

The History of Human Flight
Mankind's exploration of flight had a long history and was full of challenges. In ancient times, the dream of flying had existed in various cultures. For example, in Greek mythology, Icarus and Dadaros used artificial wings to fly. Although they ended in failure, they reflected the human desire for flight. In China, around 400 B.C., Mozi and Luban invented the kite, a man-made flying device. At the same time, Chinese toy manufacturers also invented bamboo helicopters. The ancients also discovered the basic mechanism of hot air balloons and invented floating paper lanterns. In the Middle Ages, Leonardo da Vinci proposed the theory that bird-shaped wings could carry people, but it encountered difficulties in terms of power. In the 18th century, the French brothers, Josef-Michele and Jacques - Étienne Montgolfier, created the first hot air balloon that could support the weight of a human. They flew five miles over France on November 21, 1783, and demonstrated their hot air balloon. At the turn of the 19th century, the British engineer George Kelly published the paper "Air Navigation" to lay the foundation for the study of flutter. About 70 years later, Nicholas Horta created the world's first gas-powered internal combustion engine. On December 17th, 1903, the Wright brothers 'first airplane made a historic test flight. Although the brothers' flight time was only 12 seconds and 59 seconds respectively, this was the first controlled flight in human history. World War I pushed forward the development of aircraft technology, including the introduction of more powerful engines, improved wing designs, and more stable flight control systems. In the 20th century, airplanes developed rapidly. At the age of 25, Charles Lindberg completed a trans-Atlantic flight from New York City to Paris. The design of aircraft continued to vary, from biplanes to single-wing aircraft, then to jets and modern supersonic aircraft. The introduction of jets greatly reduced travel time, and the rise of commercial aviation made aircraft the main means of transportation. Today, the emergence of drones brought new possibilities to the aviation field, and researchers were also exploring more eco-friendly aircraft designs to reduce the impact on the environment.

A brief history of human flight
" Enlightenment from a brief history of human flight." The brief history of human flight is a magnificent epic filled with dreams, explorations, setbacks, and breakthroughs. It gives us many profound inspirations. From the initial yearning of humans for flight, it originated from the curiosity and exploration of the unknown world. As early as ancient times, all ethnic groups had myths and legends about flight. Although the technology at that time could not achieve flight, this yearning was like a seed, deeply buried in the hearts of humans. For example, Icarus in ancient Greek mythology, although his flight towards the sun ended in tragedy, it reflected the human heart's desire for the sky. China also has artistic images such as "Flying Heavens", which shows that human dreams of flying are not bound by realistic conditions. This shows that dreams are a powerful driving force for human progress, no matter how far it seems at the time. In the course of human flight development, it had experienced countless failures. From Da Vinci's detailed flight theory research to the various setbacks of early flight experiments, such as the inability of early aircraft to fly continuously or the flight distance was too short, but humans did not give up. Since the end of the 18th century, with the promotion of the industrial revolution, aviation technology developed rapidly. Modern aircraft such as hot air balloons, airships, gliders, and airplanes were introduced one after another. This process tells us that we must have perseverance in the face of failure, and constantly learning from failure is the key to success. Every failure was a step towards success. As long as he continued to work hard, he could continue to make progress on the road of exploration. Moreover, the development of human flight was inseparable from the application of cross-disciplinary knowledge and innovative thinking. Sir George Kelly identified the four forces of flight and proposed the concept of a fixed-wing aircraft. This not only involved the knowledge of physics in terms of aeromechanics, but also required an innovative way of thinking to combine theory with practice. From ancient kites, bamboo dragonflies, and other simple flying devices to modern complex airplanes and helicopters, each stage was the result of the continuous accumulation of human knowledge and the continuous use of innovative thinking. This inspires us to break through the limitations of traditional thinking and actively use multi-disciplinary knowledge for innovation in the face of various challenges in order to achieve greater breakthroughs. In addition, the brief history of human flight also reflected the relationship between cooperation and competition. In the process of flight development, there was competition between different countries, scientists, and inventor, such as the hot air balloon competition between the Mongofia brothers and their competitors, Jacques Alexandre Charles and Nicholas Louis Robert. There was also cooperation and knowledge sharing. This kind of competition prompted all parties to continuously improve their technical standards, while cooperation accelerated the overall development of flight technology. This reminds us that in the process of personal development, corporate competition, and even national development, we must correctly handle the relationship between competition and cooperation. Competition motivates progress, and cooperation fosters common development. The brief history of human flight was like a vivid textbook. Its enlightenment was not only limited to the field of flight, but also had far-reaching significance for the development of all aspects of human society. It inspires us to have dreams, not be afraid of failure, be brave in innovation, be good at cooperation, and constantly explore the unknown.

Illustrated History of Human Flight
The following was a poster about the history of human flight: [1. The flying element in myths and legends] 1. ** Ancient Egypt * - The goddess Isis in ancient Egyptian mythology was depicted in ancient Egyptian bronze embossed paintings as flying in the air with her wings spread out. She was in charge of life, magic, marriage, and fertility. She used her wings to protect her subjects, which reflected the fantasy of flying in ancient Egypt. 2. ** Ancient Greece * - The legend of Daedalus and his son Icarus. After they were imprisoned on the island by King Minos, Daedalus glued their feathers together and sealed them with wax to make wings. The father and son flew across the Aegean Sea. This was a mythical story about flight in ancient Greece. ** 2. Early Flight Trials ** 1. [China] - The kite was probably the first form of man-made airplane. It was said that it was invented by Mozi and improved by Lu Ban. The wooden kite made by Lu Ban could be used for communication and detection during war. It could also be used as a weapon for war. - Sky Lantern (Kong Ming Lantern) was said to have been invented by Zhuge Liang. Its principle was the same as that of a hot air balloon. It used the buoyancy of hot air to lift the ball into the air. In ancient times, it was mostly used for military purposes, while modern people used it to pray. For example, the Mongols used dragon-shaped sky lanterns to transmit signals during the Battle of Lignitz. 2. ** Western "Flying Man" tries ** - In 1507, John Damian jumped from Stirling Castle in Wales and tried to fly, but he broke his thigh. There were also flying people who put on special cloaks and jumped from high places. Although these actions failed and even killed, they took the first step in human flight practice. ** 3. Development of aircraft ** 1. ** Ornithopter ** - The appearance of the ornithopter after the 17th century was a major advancement in the history of aviation. It was in the transition stage from ancient flying people to gliders and airplanes. Da Vinci was the most famous figure among the researchers of the ornithopter. He left behind many research manuscripts and sketches about the ornithopter, including descriptions of the flying birds and gliding, as well as machine sketches. 2. ** Hot air balloon and airship ** - On November 21, 1783, the Mengerfei brothers made the world's first manned hot air balloon flight. They took off from the Bois-de-Boulogne in the west of Paris and flew for 25 minutes in the air before finally landing near the Place d'Alitalia in the 13th arrondisse of Paris. This was 120 years earlier than the Wright brothers 'flight. - On July 2, 1900, the world's first airship, the Zeppelin LZ1, flew for the first time in Germany. Its take-off was recognized as the beginning of the "Golden Age of Airships." The Zeppelin airship also became synonymous with the rigid airship. After the technology matured, it promoted the development of large-scale airship. 3. ** Glider ** - Although the practical ornithopter was not actually manufactured, a glider was derived from the test process. Otto Lilindahl was the most important pioneer in glider research. He published Bird Flight as the Foundation of Aerospace, which analyzed the shape and structure of bird wings in detail and applied them to practical flight. He was also the first person to fly a fixed-wing glider more than 2000 times. 4. ** Powered aircraft related ** - On May 6, 1896, the American inventor Samuel Pierpont Langley conducted a successful test flight of an unmanned aircraft model "air station" on the Potomac River near Washington. The model aircraft catapulted off from the ship for about half a mile. This was the first sustained powered flight of an aircraft with a gravity greater than air. - On December 17, 1903, the Wright brothers of the United States had four test flights and flew into the blue sky with the "Flyer 1". Although the longest flight time only lasted 15 seconds and the flight distance was 66 meters, it was a major breakthrough in the history of human flight. It marked the dream of flying for thousands of years from a myth into reality. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
