The comparison of the Boeing 787 and the McDonnell Douglas DC-10 illustrates significant advancements in widebody aircraft design over time. Although the 787 is recognized as a ‘small widebody,’ it surpasses the DC-10 in size and range, reflecting the trend towards larger and more efficient aircraft suited to modern market demands. This shift aligns with the enhanced operating efficiency of narrowbodies like the Airbus A321XLR.
