The Boeing 747 has carried more than two billion passengers over three decades, a distance the film calculates at roughly 42,000 round trips to the Moon. This episode of the Great Planes series traces how the aircraft came to dominate long-haul travel, opening with the jet age Boeing entered and the gamble the company took to build the first wide-body airliner. Archival footage and engineering interviews cover the plane's distinctive hump, its four-engine layout, and the manufacturing challenges of assembling a fuselage that size in the 1960s. The film walks through the 747's effect on airline economics, making transatlantic and transpacific flying affordable for ordinary travelers instead of a luxury reserved for the wealthy few. It also covers the aircraft's role as both passenger carrier and cargo workhorse, and the incremental redesigns that kept it flying commercially for decades. The result is a straightforward account of one plane's engineering and its outsized effect on how the world travels.
