The creature crouches low when walking in forests. Its senses are heightened by the thrill of a hunt. It stalks its prey from the ground up to tree branches and unto the jungle canopy. Branches are leap frogged as the hunter pursues the prey from atop. The grip loosens and hunter falls down with a great thud and death follows. If the story were converted to the present it would not happen as emergency parachute will be deployed.
Tool using was an important milestone in the evolution of civilizations. Other creatures also used tools but the routine use and application that took place separated hominids from the apes. Early tools were crafted from materials that would rot such as sticks and animal bones. Stones were chipped to create sharp edges. Examples of this from as far back as two point five million years ago can be seen in museums.
Sharpened stone adzes have been discovered around bone remains of what used to be hunted animals. This is proof that hominids intentionally cut rock edges to make shear through soft tissue. At a later date, handles were attached to the adzes which now became hand axes. The added handle provided more torque and force when wielded with extended arms.
People by nature like to explore. The spirit of adventurism is ingrained it its psyche. The flight of a bird has enthralled man from the time it was observed. This dream of flight encouraged mankind to think of methods that can make an individuals fly. Human flight was first achieved with the use of balloons. This was a result of hot air rush inside light containers that did not burn.
Efforts were made to copy bird motion in full flight. Observations were made on how the legs, the wings, and the tail behaved while flying. But all this came to naught as the force needed to escape the gravitational pull of the earth needed to have a more powerful source and this came with the creation of internally fired engines.
It was not until the start of this century that powered flight became possible. The invention of the engine showed promise in that it had enough power for sustained flight. Old designs used to emulate the shape of the bird copiously imitating the wings. Technology and engineering soon solved the riddle of air flow against surface that resulted in airplane wings.
Very rapid developments in technology have revolutionized air travel. Who would have thought that propeller driven aircraft would one day be rarely seen in the skies. Engines that spun the propellers were very powerful and efficient. But once it attained speeds approaching the sound barriers, the propellers bent and resulted in crashes.
The military was probably the first to think of an item that would slow down a descending object. Designs were submitted for testing and the right fabric was found that became the hood with strings attached to it and fixed on a man. Chutes were then innovated and improve to serve as pilot accessory in times of emergency. With it in hand, the operator and passengers could now bail out safely.
Chutes come vary in forms and sizes. The round ones are purely for drag and have no lift. It is just intended to retard the speed of the descent. The cruciform chute is primarily a military device used in special operations. Sports enthusiasts use the wing chutes which tend to move forward at high speeds but can be controlled during landings.
