Trijets

The category, explained

The trijet existed because of regulation. Before modern ETOPS rules, twin-engine aircraft were barred from flying far from a diversion airport, so an aircraft crossing an ocean needed three engines or four. Three was cheaper than four, hence the DC-10, the L-1011 and later the MD-11, each with an engine buried in the tail.

Once twins were certified for long overwater flights, the economics collapsed instantly: two engines burn less fuel than three. No trijet airliner has been built since 2000, and the last freighters are now retiring.
