``` ### Detailed Introduction The Boeing 747-200, a variant in the iconic 747 family, is one of the most significant aircraft in the history of aviation. Launched in the 1970s, this model was a game changer, revolutionizing long-haul air travel with its unique design, capacity, and efficiency. It is a wide-body airliner that not only offered unprecedented passenger capacity but also redefined the concept of speed and range. This variant of the 747 was introduced in 1971, following the original 747-100, and became known for its ability to carry more passengers and cargo over longer distances than its predecessors. With its distinctive hump on the upper deck, the 747-200 was not just a marvel of engineering; it was also a cultural icon that opened doors to international travel for millions of people around the world. Over the years, the 747-200 served various roles, from commercial passenger flights to cargo transport, and even as a platform for scientific research and military use. While it has largely been replaced by more efficient and modern aircraft, its legacy lives on in the airline industry. The introduction of the Boeing 747-200 marked a pivotal moment in commercial aviation, as it was one of the first aircraft to accommodate the burgeoning demand for air travel in the late 20th century. By offering a capacity of up to 660 passengers in a single-class configuration and around 400 in a typical two-class setup, it made intercontinental travel accessible to the masses. Moreover, the aircraft's performance specs were impressive for the time. With a range of approximately 6,500 miles, the 747-200 opened up new routes and possibilities for airlines, particularly for transoceanic travel. The aircraft's four-engine setup, powered by Pratt
