Boeing 737 Twinjet
The Vought F7U Cutlass was one of the first modern twinjet fighters.

A twinjet or twin-engine jet is a jet aircraft powered by two engines. A twinjet is able to fly well enough to land with a single working engine, making it safer than a single-engine aircraft in the event of failure of an engine.[1] Fuel efficiency of a twinjet is better than that of aircraft with more engines.[2] These considerations have led to the widespread use of aircraft of all types with twin engines, including airliners, fixed-wing military aircraft, and others.
