Ok, here's a description about my flesh-eating Concordes. Feel free to ask questions.

The flesh-eating Concordes are biomechanical carnivorous living planes, developed by the French and British Air Forces for use as a weapon. They are well designed for supersonic flight, having delta wings and a streamlined profile. All Concordes have similar coloration, composing of white wings and fuselage, a dark blue stripe running down each side of the fuselage, and a dark red vertical stabilizer with a white leading edge. The Concordes’ most striking feature is that there are two variants. The two variants are differentiated by size: smaller Concordes and full size ones. The smaller Concordes, which are more numerous, are fifty feet long, have a thirty foot wingspan, and are thirteen feet tall. The full size Concordes are two hundred and four feet long, have an eighty-five foot wingspan and are close to forty feet tall.

For more than a decade, international tensions between France and the UK and Russia had been brewing. In the event of warfare between the countries, the air forces of France and the UK decided to create a fleet of killer planes to attack and feed on enemy troops, believing them to be the perfect weapon against the Russian military. After ten years of development, the first Concorde was hatched at a military base in Toulouse, France. It was extremely vicious and killed people indiscriminately. Despite this, the French government ordered that the plane not be destroyed and instead insisted that the military continue to work on it so it would attack designated targets only. At the same time, the militaries of both France and the UK stated they desired a fleet of several thousand Concordes. More Concordes were hatched in both countries and were subsequently placed in specialized holding facilities as work progressed to get them to attack only desired targets. The governments of France and Britain believed that it was more important to acquire a large Concorde fleet before getting them to attack only designated targets, thinking that acquiring the desired number of planes would be more difficult than having them attack predetermined targets only. The Concordes continued to kill indiscriminately and work continued constantly to solve this problem.

As tensions with Russia grew, a terrorist organization based in Moscow had been planning an attack on France and Britain as a political statement to not declare war on Russia. As the holding facilities for the Concordes were being built, a Russian citizen in the French military with ties to the terrorist organization designed the security systems for the computers at the holding facilities. Since the Concordes were a top-secret project, he knew little of the Concordes themselves, aside that they were man-eating planes. Seeing the potential to launch a terrorist attack, he designed the security systems with weaknesses as well as a computer virus capable of disabling the system completely. It would cause the electric bars in the holding facilities to shut down, allowing the Concordes to escape. The virus was also designed to spread to all the holding facilities in both France and the United Kingdom. Soon afterward, the French military discovered his ties to the terrorist organization and deported him back to Russia before he had a chance to release the Concordes. He brought with him to Russia a flash drive containing the virus. Several years later, a different member of the terrorist organization traveled to Paris and hacked into the security system of a Concorde holding facility twenty miles outside the city. He implanted the virus into the system which quickly spread to all the holding facilities, before shutting down the electrified bars holding the Concordes in, allowing them all to escape.

There are two sizes of Concordes; smaller Concordes and full-size ones. The smaller Concordes are close to fifty feet long, have a thirty foot wingspan and are approximately twelve feet tall. The full-size Concordes are slightly over two hundred feet long, have an eighty-five foot wingspan and are close to forty feet tall. The smaller Concordes are more numerous and are usually found in greater numbers throughout cities while the full-size Concordes tend to stay outside areas where large buildings are present. This is because the smaller Concordes are more adept at flying between buildings due to their smaller size and shorter wingspan.

Unlike other planes, the Concordes are flexible in certain areas. This is because they are covered in microscales rather than rigid plates of metal other planes are covered with. The microscales are too small to be visible to the naked eye and are small enough that they provide a smooth streamlined surface, as opposed to a rough one. They overlap each other, much like the feathers of a bird. The few areas the Concordes are flexible are their jaws so they can open their mouths and the area behind their heads. They are constructed out of a semi-organic form of carbon fiber. This material is light, yet very strong, and able to withstand gunfire to a degree.

To locate potential prey, Concordes have extremely sharp vision. Instead of eyes, they have powerful visual sensors that allow them to see in much the same way as humans. However, the planes can see objects from a much greater distance than humans and in more detail. For example, they are able to spot a human from more than five miles away. They do not have “telescope vision”, instead they are able to see in much greater resolution than humans, allowing greater detail. The vision of Concordes in not limited to only the visual spectrum. They are able to see in complete darkness and also in infrared, allowing them to hunt at night and to allow them to view prey from behind a barrier, such as a building due to their body heat.

They also have a structure inside their mouths similar to the Jacobson’s organ found in certain animals. It allows the plane to detect the scent of flesh from several miles away. They are especially sensitive to the scent of blood.

Concordes owe their success as aerial predators to their incredible speed. They can easily and quickly reach their cruising speed of 1350 miles an hour, which is Mach 2. Most fighter jets are able to fly faster than them, but Concordes can fly at supersonic speed for much longer than fighter jets. They have sharply pointed nosecones, a slender fuselage, and delta wings to achieve as streamlined profile as possible. The highest they fly is 60,000 feet. At this altitude, the planes cannot be seen from the ground with the naked eye.

The Concordes are the most aerodynamically advanced aircraft in existence. They are able to outmaneuver fighter jets and anti-aircraft missiles, making them difficult to shoot down. Their maneuverability allows them to fly between buildings as they chase down prey in urban areas. Since they have talons for landing gear rather than tires, the planes can take off and land without the use of a runway. Much in the same way as birds, they can take off by lunging into the air and land by grabbing onto the ground with their talons.

Unlike most planes, the Concordes can fly without the use of their engines. Because they are very lightweight compared to their size, they are able to soar on air currents in the same way as birds of prey. They are able to soar for hours and glide between air currents. However, they cannot fly very fast without the use of their engines. Concordes typically soar when they hunt. The slow flight allows them to scan vast areas carefully for signs of prey. However, the full-sized Concordes rarely fly without the use of their engines due to their size and weight.

The Concordes are carnivorous planes. Humans are their preferred prey, but if there are none around, they will feed on medium to large animals such as cattle, deer, horses, ect. They are able to process their preys’ flesh into a type of fuel that is used for flight and substance, including the largest bones. It serves that same purpose as petroleum-based fuels but has an entirely different chemical composition. Meat is converted to liquid fuel in large chambers in the Concorde’s fuselage, a process that takes about an hour. The fuel is then channeled into large tanks in their wings. Small Concordes typically devour around 100 humans a day compared to the full-sized ones which normally eat around 550-600 a day. Such high energy requirements entails that Concordes spend the majority of their time hunting and they will stop at nothing to satisfy their insatiable appetite for raw, fresh meat.

Concordes have powerful teeth and talons. Their jaws are lined with close to sixty razor-sharp teeth. They are uniformly the same in shape and size. In the smaller Concordes they are usually around eight inches long and the full-size Concorde have teeth twice that length. The teeth of Concordes are finely pointed and slightly curved backward, with the back edge serrated, making them well-suited for tearing off large pieces of flesh. They are able to fold back into the jaw when the plane closes its mouth so teeth would not protrude from its mouth and cause air resistance during flight. Their jaws are also very powerful. The bite force of a small Concorde is roughly 75,000 pounds per square inch while the bite force of a full-size Concorde is about 200,000 PSI. Their incredible bite force allows them to bite though almost anything, including thick steel. Their long jaws are sharply pointed to make the Concordes more streamlined for supersonic flight but they do use them to stab at prey.

Instead of tires, the landing gear of the Concordes are talons. They have four landing legs, one under each wing and two more under the forward fuselage behind their head. Like most planes, they can retract their landing gear into their wings and fuselage while flying. On each landing leg is four razor-sharp talons that are used to grab and tear at prey. The layout of the talons is much like the foot of a bird. Three talons face forward while a fourth larger one faces backward. The forward facing talons are used for tearing and gripping objects with incredible force while the rear-facing talon is used for deep gouging. Concordes are able to exert tremendous crushing force with their talons; this force is slightly less than that of their jaws. However their curved talons and the large rear-facing ones make it somewhat difficult for the planes to move quickly on the ground.

Concordes almost always attack their prey from the air. They hunt either flying or perched on an elevated surface such as a building. When they notice prey, they lunge at their prey with their talons extended. They will either eat their prey on the ground or carry it off to a rooftop. When there are many Concordes in an area, they will eat their prey on the ground instead of carrying it off elsewhere to reduce the chances of another Concorde stealing its catch. To further reduce the chances of a Concorde having its prey stolen, the plane will mantle its prey as it feeds, in which it positions itself so that its wings obscure the catch from the air. Concordes are notorious for eating humans while they are still fully conscious and screaming. They usually don’t bother with even trying to kill their prey before they start to eat them, even though they are fully capable of doing so very easily. Instead the planes pin their prey down with their landing gear and tear off pieces of flesh as the human screams. When feeding, Concordes tend to keep their prey alive as long as possible since they eat the vital organs and major arteries last.

Concordes attack most often in groups but it is not uncommon for them to hunt alone. Gregarious in nature, Concordes typically attack in groups ranging from a few individuals to several hundred. When they attack in large groups, they swarm numbering in the hundreds and devour every human they see.

Concordes are extremely aggressive and will attack almost anything that will provide them with food. For example, they relentlessly attack buildings to get at the humans within. The extent of these attacks is they usually break through the windows and grab humans in their jaws. However, they can and do launch large-scale attacks on buildings that can lead the collapse of very large skyscrapers. As the Concordes attack, they target the main support beams. Since their jaws are so powerful, a group of Concordes could eventually chew through a building’s support column, leading to collapse of the structure. As humans try to flee, they would get attacked and eaten by the Concordes. However, they usually don’t bring down buildings with large flat tops since they serve as potential nest sites. In addition to attacking buildings, Concordes will also attack other planes. With their powerful jaws and talons, they can easily tear apart the wings, tail section, and fuselage. They are relentless and do not cease their attack until the plane is brought down in order for them to feed on any survivors.

Concordes are highly intelligent and have excellent problem-solving capabilities. While hunting, they are able to anticipate the actions of their intended prey and even set traps.

They can communicate very effectively with each other. Concordes have nearly ten thousand different calls, approximately half of them ultrasonic. They are able to vocalize by inhaling air into a resonating chamber located in the forward section of their fuselage. It compresses air as the Concorde exhales, producing sound. This structure is similar to the syrinx found in birds. These calls range from shrieks, screams, hisses, chirps, screeches, and whistles, all harsh and high-pitched. Their most prominent call is a long, drawn-out scream that can be heard for miles. This scream best resembles the call of a red-tailed hawk combined with that of a macaw, but harsher and higher in pitch. This call is used to communicate with Concordes over a long distance. With such a large variety of vocalizations, the Concordes are able to communicate very effectively.

Concordes are usually found in groups. The sizes of these groups can range from a few individuals to several hundred. However, these groups have very little structure. There is no alpha Concorde or any sort of pecking order. As a result of this, fights are commonplace, especially over food. When one Concorde makes a kill, others may try to steal it. These fights may appear to be vicious, but it is rare for planes to sustain significant damage. This lack of social structure is evident when they attack large targets as a group, such as a building. They attack en masse rather than carrying out a coordinated attack.

Concordes are able to breed but are genderless so therefore they reproduce asexually. Despite that they reproduce asexually, they form pairs when they breed so that one stays at the nest while the other hunts. If a Concorde raised its chicks alone, it would not be able to defend the nest while providing a sufficient supply of prey. Year round, they choose “mates” based on their strength and hunting abilities. Each plane will carefully inspect each other for signs of fitness. If the two Concordes accept, they will undertake special courtship flights where each Concorde has to copy exactly the other’s maneuvers. This aerial dance climaxes when the Concordes circle closely upwards to sixty thousand feet. Once they reach this altitude, they lock talons and freefall toward the ground. As soon as a crash seems unavoidable, they quickly unlock their talons and fly upward to repeat this flight several more times.

If the Concordes accept each other as partners, they select a location for their nest, which is typically the roof of a skyscraper. Instead of constructing a large nest, they usually line a small section with loose materials they find, such as pieces of metal, tree branches, and large bones from prey. Soon after the nest is completed, each Concorde lays its eggs. Smaller Concordes usually lay two each and full-size Concordes lay one each. The eggs are tan covered with dark brown asymmetrical marks that usually take a month and a half to hatch. They do not need to be incubated, but the parent Concordes will usually crouch over them to hide them from view from other Concordes that may try to take the nest site.

Hatching is a process that takes several hours. The hatchlings of smaller Concordes are usually around eight feet long while the hatchlings of full-size Concorde typically are twenty feet long. After hatching, the wings and fuselage of Concordes are soft and bendable to accommodate them in the small and cramped egg. Soon after hatching, they begin to stiffen, a process that takes several days. Soon after hatching, the young Concordes are ready to feed for the first time. One of the parent Concordes drops a human into the nest for them to attack and eat. Even hours after hatching they are agile on the ground and are well-suited to attack and bring down prey. Humans are delivered to the nest fully alive and conscious before they are attacked and eaten alive by the young Concordes. Their teeth may be small but they are well-suited for tearing flesh. Concorde chicks are able to strip a human to the bone in less than ten minutes, less for the chicks of full-size Concordes. They are usually unable to eat the largest bones of their prey, so these are usually eaten by the parents. Competition among chicks can be intense, especially among full-sized Concordes. Smaller Concordes lay two eggs each and it is not uncommon for the fourth and thus youngest chick to be viciously attacked by its siblings. Full sized Concordes lay one egg each and the oldest chick almost always attacks the youngest. As the young Concordes get older, they become less aggressive towards each other. As the chicks get larger, they require more meat to sustain themselves. At this point, they are left unguarded by their parents for extended periods of time as they both hunt. The parent Concordes spend much more time than usual hunting because they need to provide for their chicks as well as themselves. Since the young planes are not yet flying, their prey requirements are considerably less than that of their parents.

Concordes do not establish a large territory around the nest but defend only a small area around it. Usually a Concorde stays at the nest while the other hunts for food to defend it from other Concordes that may try to drive the pair away from the nest site. They take turns guarding the nest and hunting, with each turn lasting several hours. If another Concorde gets too close to the nest, the nesting Concordes will not attack it immediately. They will attempt to drive away the intruder by hissing fiercely at it. If it does not leave or gets closer to the nest, they will attack. As the chicks get older, the parents become less aggressive since they are able to defend themselves more easily. They also spend much less time at the nest, only visiting it briefly to drop food off for the young Concordes.

When they are about a year old, the young Concordes have reached their full adult size. They are able to increase their size due to properties present in the carbon fiber material that they are composed of. It is a semi-organic material arranged in tiny microscales which has the ability to replicate, which therefore allows a young Concorde to increase in size.

As soon as a young Concorde reaches its adult size, they begin to fly. Their first flights are usually short glides from one side of the building the nest is on to the other. Soon after, the parent Concordes place prey on top of adjacent buildings so the chicks fly longer distances as well as improve their hunting abilities. The parents also feed the chicks less to encourage them to hunt for themselves. As the chicks learn to fly, they also learn to hunt. Because they attack quickly from the air, hunting humans is a fairly easy skill for them to master, leaving them with more time to improve their aerobatic abilities. However, since they are inexperienced hunters and fliers, their first hunts can be hazardous. Young Concordes have been known to focus so intently on chasing their prey that they end up crashing into the ground. For most planes, it usually takes about a month to hone their flying and hunting abilities.

Once young Concordes are able to successfully hunt for themselves, their parents drive them away from the nest, which is more than a year after they hatch. Juvenile Concordes look identical to adults but their calls have a slightly harsher quality. During their first few years, they often form groups within the large main Concorde group with other juveniles for protection from the more aggressive adult Concordes. They also further hone their hunting and flying abilities before they reach maturity. Some older juveniles (usually ones older than three years) leave the group because they are able to compete with adult Concordes over prey. Other juveniles stay within the group until they reach maturity at five years and leave when they search for a mate.

In 2011, the Concorde population started at 3,000, with their population growing at a rapid rate since then. A rather fast breeding rate, surplus of prey, and the extreme levels of difficultly and danger involved in shooting them down contributes to their population growth. Within several years after their release, their population had doubled. In a period of several decades, their population had exploded and doubled on multiple occasions. At the end of the 21st century, their population reached one million individuals.

One of the parent Concordes drops a human into the nest for them to attack and eat. Even hours after hatching they are agile on the ground and are well-suited to attack and bring down prey. Humans are delivered to the nest fully alive and conscious before they are attacked and eaten alive by the young Concordes. Their teeth may be small but they are well-suited for tearing flesh. Concorde chicks are able to strip a human to the bone in less than ten minutes, less for the chicks of full-size Concordes. They are usually unable to eat the largest bones of their prey, so these are usually eaten by the parents. Competition among chicks can be intense, especially among full-sized Concordes. Smaller Concordes lay two eggs each and it is not uncommon for the fourth and thus youngest chick to be viciously attacked by its siblings. Full sized Concordes lay one egg each and the oldest chick almost always attacks the youngest. As the young Concordes get older, they become less aggressive towards each other. As the chicks get larger, they require more meat to sustain themselves. At this point, they are left unguarded by their parents for extended periods of time as they both hunt. The parent Concordes spend much more time than usual hunting because they need to provide for their chicks as well as themselves. Since the young planes are not yet flying, their prey requirements are considerably less than that of their parents.

Concordes do not establish a large territory around the nest but defend only a small area around it. Usually a Concorde stays at the nest while the other hunts for food to defend it from other Concordes that may try to drive the pair away from the nest site. They take turns guarding the nest and hunting, with each turn lasting several hours. If another Concorde gets too close to the nest, the nesting Concordes will not attack it immediately. They will attempt to drive away the intruder by hissing fiercely at it. If it does not leave or gets closer to the nest, they will attack. As the chicks get older, the parents become less aggressive since they are able to defend themselves more easily. They also spend much less time at the nest, only visiting it briefly to drop food off for the young Concordes.

When they are about a year old, the young Concordes have reached their full adult size. They are able to increase their size due to properties present in the carbon fiber material that they are composed of. It is a semi-organic material arranged in tiny microscales which has the ability to replicate, which therefore allows a young Concorde to increase in size.

As soon as a young Concorde reaches its adult size, they begin to fly. Their first flights are usually short glides from one side of the building the nest is on to the other. Soon after, the parent Concordes place prey on top of adjacent buildings so the chicks fly longer distances as well as improve their hunting abilities. The parents also feed the chicks less to encourage them to hunt for themselves. As the chicks learn to fly, they also learn to hunt. Because they attack quickly from the air, hunting humans is a fairly easy skill for them to master, leaving them with more time to improve their aerobatic abilities. However, since they are inexperienced hunters and fliers, their first hunts can be hazardous. Young Concordes have been known to focus so intently on chasing their prey that they end up crashing into the ground. For most planes, it usually takes about a month to hone their flying and hunting abilities.

Once young Concordes are able to successfully hunt for themselves, their parents drive them away from the nest, which is more than a year after they hatch. Juvenile Concordes look identical to adults but their calls have a slightly harsher quality. During their first few years, they often form groups within the large main Concorde group with other juveniles for protection from the more aggressive adult Concordes. They also further hone their hunting and flying abilities before they reach maturity. Some older juveniles (usually ones older than three years) leave the group because they are able to compete with adult Concordes over prey. Other juveniles stay within the group until they reach maturity at five years and leave when they search for a mate.

In 2011, the Concorde population started at 3,000, with their population growing at a rapid rate since then. A rather fast breeding rate, surplus of prey, and the extreme levels of difficultly and danger involved in shooting them down contributes to their population growth. Within several years after their release, their population had doubled. In a period of several decades, their population had exploded and doubled on multiple occasions. At the end of the 21st century, their population reached one million individuals.
