The first of its class Truly the first Jumbo jet, Boeing 747 also referred to as “The queen of the skies” is in service for over 50 years now. It was introduced in 1970 to the public with the now-defunct company Pan Am which wanted a large airplane that could lower the price of tickets for the average paid man. Boeing accepted the challenge and designed a four engines, two-deck airplane that now has decades of faithful service. The thing that differentiates the 747 from other airplanes is its specific hump that houses the cockpit, a feature that makes this airplane not only a great passenger aircraft but a cargo-capable one too. For Boeing 747 to become a reality, it needed a big factory which the company constructed in Everett, 50 km outside Seattle and almost three million cubic meters of earth had to be moved to make space for a queen palace. But the queen had its problems too, initially, the airplane did not meet the FAA requirements for the evacuation process which had to be done in 90 seconds, then, the pilots were not trained for such high deck airplanes so Boeing mounted a cabin above a truck to make pilots train for taxing. The 747 had problems with its structure also when tests showed that wings suffered oscillations under certain conditions but this was solved by reducing the stiffness of some wing components, however, a particularly severe high-speed flutter problem was solved only after depleted uranium counterweights were introduced in the outboard engine nacelles of the early 747s. This measure worried people, especially when these aircraft crashed, for example in 1992 in Amsterdam, the airplane had 282 kilograms of uranium in the tailplane. This and other problems did not stop Boeing from bringing the 747 to Paris Air Show in mid-1969, where it was displayed to the public for the first time. Before the end of development, the company was over $2 billion in debt to a banking syndicate, and if the airplane was a failure this could have meant the end of Boeing, but the gamble succeeded and Boeing had the only Jumbo Jet at the time and held a monopoly in this category for many years. The program’s final cost was 1 Billion US $ (7.4 Billion today). On January 15,…
