Where can I find information about sky diving? Read this article for useful tips.
Before skydivers jump in the air, they first try to inspect the materials they are going to use to ensure safety. They are supposed to use 2 parachutes during the jump. The first one is the main parachute and the other one is used for emergency purposes. The skydivers place them at their backs. They also go under a discussion with the pilot to know the condition of the weather and which spots the divers are supposed to jump. They also plan the order on which the skydivers are jumping and how to achieve a safe landing. While on the ground,they then practice the moves they're going to do while on the air.
The skydivers then also climb aboard an aircraft and brace themselves for takeoff. The aircraft then climbs up to an altitude of between 10,500 to 13,800 ft. The pilot and another person checks on the spot where the skydivers are going to jump. This stage is called a jump run. Once each skydivers' turn comes,they then step away from the aircraft and execute 1 minute freefalls using their planned maneuvers. They then fall at approximately 120 to 150 mph. They execute their maneuvers such as stretching out their arms and legs to control the air resistance around them. Once they're flying at about 3,900 ft., the group then separates from one another until there's enough space to prevent them from bumping into each other. They wave their arms as a sign of opening their parachutes. They then use a pilot chute which is folded in their parachute system to open the main parachute. As it opens, air enters inside it and it takes the shape of a canopy to slow the skydiver's descent. This act all takes about 3 to 5 seconds. The skydiver controls the parachute's direction by pulling two basic controls called toggles. Pulling one toggle slows and leads the parachute on a certain direction.Pulling both of them slows the person's descent and forwards the speed of the jumper simultaneously. When the skydiver is about to land,he flares the parachute to achieve good landing. They then run on their feet upon landing or roll themselves in a forward manner to avoid further injury.
Rugs: North American Rugs - Navajo rugs, American Indian rugs and native American rugs
North American is the name given to flat weave rugs and blankets woven by Native Americans in the Central Western areas of the US, mainly in Arizona, New Mexico, Utah, and Colorado. These rugs are better known as Navajo rugs.
The weaving of Navajo rugs is the continuation of a long tradition of excellent craftsmanship that dates back nearly three centuries.
It is believed the Navajos learned the craft from the Pueblo Indians around 1700, as early examples of Navajo weaving show the close parallels between the two groups. The principal difference between Navajo and Pueblo weaving is that the Navajos used wool, while the Pueblos used cotton.
In the mid 1800s, the Navajos started using dye sources and yarns from the Europeans, especially the Germans and Spanish. Along with dyes and commercial yarn, the Europeans brought designs that could be incorporated into the flat weaves of the Navajos. These were usually Oriental patterns, which the Europeans apparently couldn't get enough of.
From the Navajo's own designs, the most famous examples were the 'Chief Blankets', which were worn on the shoulders of the tribe's chief. These items were extremely popular with the other Plain's Indians.
Navajo weaving changed radically in the last twenty years of the 19th century. Commercial ready-to-use yarns were available in a variety of colors, and by 1890 the Navajo Indians were weaving mainly for the trading posts and white tourists.
The traders were a great influence on the weavers, and the requests for pillow covers and bed covers to decorate white homes resulted in a proliferation of quickly woven, inferior pieces.
By 1890, after many years of blankets and bed coverings, white settlers were demanding covering for the floor. The Navajo rugs were born as the Indians were quick to oblige.
The Indians were now weaving less of their traditional simple and abstract geometric designs and more American pictorials designs including patriotic patterns and railroad scenes and houses. The traditional rugs are virtually lost and very rare today and designers seem todesire their 'Aztec' look for modern settings.
There are a few settlements that might still be weaving Navajo rugs, but much like all the other aspects of the Indians' culture, the Navajo rug is but a faint memory to them.
