It is interesting to see how much commercial aircraft design has evolved over time.
Aircraft like the DC-10 and Lockheed L-1011, which were once among the largest passenger jets after the Boeing 747, would now be considered similar in size and capacity to smaller modern widebody aircraft such as the Boeing 787-8 and Airbus A330-200.
Today, newer twin-engine widebodies like the Boeing 777 and Airbus A350 have effectively taken over the “jumbo jet” role in terms of passenger capacity and overall scale, surpassing older trijet designs by a significant margin.
Despite this, there are still design similarities across generations. For example, the Airbus A350 reportedly shares a similar fuselage diameter with earlier trijet aircraft, although it is longer and has a larger wingspan. The Boeing 777 also stands out with one of the widest single-aisle widebody fuselages in commercial aviation.
Overall, the comparison highlights how modern efficiency-focused twinjets have grown to match or exceed the capacity of older, larger-looking trijet aircraft.
