Millions of people use flights every day, and for many this is already common.
According to the International Civil OrganizationAviation (ICAO), in 2017, 4.1 billion people (almost half of the world's population) made flights by regular flights. This is 7.1% higher than in 2016. According to ICAO, the most active passenger traffic is growing in developing countries.
In total, in 2017, 37 million passenger flights set off.
But dramatic changes began with the orderBoeing President William Allen on the development of the world's largest aircraft. It was a controversial decision to take enormous financial risks, to put the company on the line for the sake of this aircraft.

The impetus for creating the Boeing 747 became immediatelyseveral factors: the need to reduce the cost of air tickets, the increase in passenger traffic on air transport and the constantly growing load of airspace. After losing the competition to the giant C-5A military transport aircraft, Boeing decided to develop a new improved civilian aircraft, taking advantage of engine technology with a high degree of bypass.
The design philosophy of the 747 was characterized in thata fundamentally new aircraft was developed, with the exception of engines. Designers deliberately avoided using any equipment designed for the C-5. Many have said that the new aircraft will not fly, either literally or financially.
However, in 1969, when the invention was presented to the world, the entire air transport paradigm changed. On February 9, 1969, the Boeing 747, dubbed the Jumbo Jet by the press, first flew into the sky.
Over 747-m worked about 50 thousand Boeing employees. It was they who, in less than 16 months, built the largest civilian aircraft in the world, the Boeing 747, at its plant in Everett, Washington. The final draft provided for three configurations of the aircraft: passenger, cargo and convertible passenger-cargo model.
Special in the family
The 747th was really stunned by its size. This huge aircraft demanded the construction of a 5.6 million cubic meter assembly plant. m - the company has become the largest structure in the world in terms of volume. The length of the first 747's fuselage was 68.5 m, and the height of the tail unit corresponded to the height of a six-story building. When sealing the cockpit, the plane was carrying a ton of air. The luggage compartment could hold 3,400 pieces of luggage and was unloaded in seven minutes. The total area of the wing was larger than the basketball court. And while the entire global navigation system weighed less than a modern laptop.
Pilots for the 747th prepared at the flight schoolBoeing company. The experience of taxiing at the helm of such a large aircraft was acquired with the help of an ingenious invention called the Waddell’s Wagon (High Tech) in honor of Boeing's senior test pilot Jack Waddell. The pilot was sitting in a mock-up cabin located on racks three floors high and mounted on the roof of the truck. So the pilot learned to fly a plane in such a high cockpit position. The actions of the truck driver were monitored by radio.
In the new aircraft was presented a numbertechnological and aviation innovations, the invention of the design of a wide-body aircraft was pivotal and revolutionary, and a turbofan engine with a high bypass ratio was used for the first time in commercial aviation.
In addition to size, comfort and efficiencyThe most important criterion for modern passengers is safety. Under the leadership of Chief Engineer Joe Sutter, the design was based on unprecedented security measures at that time. Boeing introduced fourfold redundancy of hydraulic systems, redundant designs and four main landing gears (the aircraft can be operated on two — HiTech); in addition, Boeing revised the approach to pilot training, moving from strictly procedural to behavioral training.
Friendship of two giants
Joe Sutter's friendship with Juan Tripp, the legendary director of Pan American Airways, played a role in the successful fate of the aircraft, which was the catalyst for launching the 747th program.
The Boeing and Pan Am partnership marked the beginning of an erajet liners in 1958, when Pan Am took delivery of the first civil jet aircraft, the Boeing 707-120, and a year later the companies solemnly launched the first flight of the 707th and the first daily transatlantic regular flight from New York to Paris. Air traffic began to grow, and by the early 1960s, carrying capacity was reached at all major airports. Juan Tripp began the search for a larger aircraft. Then Tripp and Allen came to an agreement in the field of aircraft construction twice as large as the 707th. The meaning of the agreement reached was in the phrase "If you buy, we will build." So the 747th program was launched.
Liner as art
Very quickly, the 747th had a tremendous impact onair freight It became a landmark and obligatory attribute for global airlines and attracted passengers with its luxury and comfort. It was the size of the giant aircraft, its colossal range, passenger capacity and economy had the most significant impact, making flights available to all mankind. 747th forever marked a point in history, when any person had the opportunity to fly anywhere in the world. By July 1970, the 747th carried the first million passengers.
Boeing 747 quickly became an icon of civil aviation. It was the first aircraft with two aisles between the rows. Most air passengers have no idea on which plane they are flying, but the size of the 747 and the characteristic hump made it instantly recognizable. The original form of the fuselage is the result of skill inherent in engineering, its design is often recognized as an outstanding creation of architecture. Among other things, the 747th became part of pop culture, appearing in a number of films, TV shows and lyrics.
Airplane for all occasions
In 1976, the NASA Space Agencymodified two 747-100 in the aircraft spacecraft carrier - Shuttle Carrier Aircraft. And in 1990, two 747-200, the next modification of the aircraft, were transformed into the presidential side. In November 2005, Boeing launched the 747-8 program - the passenger 747-8 Intercontinental and the cargo 747-8 Freighter. These aircraft have incorporated innovative technologies used on the 787 Dreamliner.
747-8 Freighter made its first flight 8February 2010. The length of the aircraft is 76.3 m, which is 5.6 m longer than the 747-400 Freighter. The passenger version of the Boeing 747-8 Intercontinental operates in the segment from 400 to 500 seats, and its first flight was made in 2011.
In 2014, Boeing delivered one and a half thousandth747th, descended from the production line, in Frankfurt, the German airline Lufthansa. It became the first wide-body aircraft in history, which overcame the mark of 1,500 units.
Boeing 747 continues to play its part, heperforms the tasks that originally laid and provided the designers, allowing him to become the most efficient cargo liner in the world. In this incarnation he will remain with us for many decades, which is evidence of the durability and reliability of the aircraft.
