Aviation of the past was truly a promising one. In fact, the big impact was clearly seen in 1950 where airlines in the United States were moving more than sixteen million people a year. In 1989 the nation's airlines transported more than 450 million passengers. One of the other major advances to come out of the development of the aircraft mechanic jobs on jet engine was the ability to travel out of the Earth's orbit into outer space. Eventually, during World War II the Germans were able to successfully launch rockets that were directed from Germany to London and other enemy territories. The V-2, the first true rocket, burned a fuel of alcohol and liquid oxygen. It used gyroscopes for directional guidance and stabilization in flight. The rocket design had outer fins on the tail end for stabilization in the lower atmosphere, but had internal vanes for control in the thinner, higher atmosphere.
After the war, technological innovations on aircraft job became more sophisticated. Scientists continued to develop rocket technology, concentrating on multi-stage rockets that would allow for a powerful enough initial blast to carry the rocket out of the atmosphere, but shed the extra weight to allow enough fuel to remain to direct the rocket to the target in outer space. However, the first to accomplish a space launch of any vehicle was the Soviet Union, Sputnik I was launched on October 4, 1957, sending a satellite into outer orbit. The satellite orbited the Earth 560 miles high, with a speed of 18,000 miles per hour. The second launch from the Soviets came a month later with Sputnik II which sent a dog, Laika, into orbit. The United States followed with Explorer I on January 31, 1958, sending a satellite into space.
In 1959, four more launches were successful while avionics maintenance jobs were also expanding. The Soviet Union launched Luna I, the first craft to break free of the Earth's orbit. It passed within 5,000 miles of the moon. The second Soviet launch that year was Luna II, which landed a probe on the moon. The third Soviet craft to successfully go up was Luna III, which signaled back the first photos of the far side of the moon. The United States launched Pioneer 4, which also successfully broke free of the Earth's gravity. Said accomplishments posed a technological breakthrough on aviation career.
Several more launches followed, with animals sent up into space to determine the pressures placed on a living being in outer atmosphere conditions. In 1961, the Soviet Union successfully launched the first man into orbit. Yuri Gagarin orbited once around the Earth on April 12. On May5, 1961, Alan Shephard became the first American to go into space. On August 6 and 7, 1961, the Soviet cosmonaut Gherman Titov orbited the Earth sixteen times. On February 20, 1962, the American John Glenn orbited the Earth three times.
During the intensely competitive space race between the Soviet Union and the United States, the Soviet Union and the United States, the race for records in such areas as the first woman in space, Russian Valentina Tereshkova, the first multi-manned launch Vostok I, the first satellite to Venus Mariner in 1963 had led to several tragedies. Loopholes on avionics technician jobs were traced. Consequently, the United States lost three astronauts on a launch pad fire in the Apollo, in 1967. Virgil Grissom, Edward White, and Roger Chaffee were killed by a fire in the cabin that burned on the pure oxygen atmosphere. The flight was to be the first Apollo spacecraft in orbit. The fire delayed the space program for twenty months while scientists and engineers redesigned the vehicle. By 1971, aviation careers had another upset when the Soviets lost four cosmonauts in another space accidents.
Aircraft employment suddenly rose into greater heights of advancement when scientists turned their focus on space programs. The United States took the lead in space exploration with the first successful landing of man on the moon. It showed an extra-ordinary feat in aviation mechanic jobs which made the spacecraft landed on the surface of the moon without any technical obstacles detected. It was indeed, a record-breaking history of aviation. The United States simply demonstrated an excellent level of avionics jobs combining with its technological innovations and advancement that allowed them to send more lunar missions in space than any other countries in the world.
