The Boeing 747 is an American wide-body four-engine jetliner, known as the "Queen of the Skies," revolutionizing long-haul aviation with unprecedented capacity.





Introduced in 1970, the Boeing 747 transformed international travel by offering double-deck capacity and intercontinental range that made air travel accessible to millions. As the first wide-body jetliner, the 747 dominated long-haul routes for decades, serving as flagship aircraft for major carriers worldwide. While passenger operations have declined, the 747 remains vital in cargo operations where its capacity and nose-loading capability are unmatched.
