The Boeing 777, often referred to as the "Triple Seven," is recognized for its powerful engines and advanced design. Initially developed in 1990, it aimed to replace older models like the Douglas DC-10. The aircraft entered commercial service with United Airlines in 1995 and has since become a flagship long-range wide-body jet for Boeing.

"The Boeing 777 is notable for featuring the largest engines of any commercial airliner," according to TIME. These engines include the General Electric GE90, known as the most powerful turbofan engine ever produced. This engine series ranges from 81,000 to 115,000 pounds of thrust and was exclusively designed for the Boeing 777 family.

Boeing's decision to develop the 777X series builds on earlier models' success. The new model features composite folding wings and GE9X engines and is expected to enter service in 2026. By April 2025, over 2,300 orders had been logged for this type.

The original variants of the Boeing 777 were powered by three different engines: Pratt & Whitney PW4000, Rolls-Royce Trent 800, and later exclusively by General Electric GE90. "Both of these engines demonstrated ETOPS-compatible reliability and a modular maintenance system," according to industry sources.

In terms of engineering feats, "the aircraft features a supercritical wing which is swept at 31.6 degrees." It also boasts triple-redundant hydraulics and carbon-fiber tailplanes that contribute to its high performance.

Boeing's ability to create an aircraft capable of flying halfway around the globe while carrying hundreds of passengers showcases its unprecedented capabilities. Despite initial challenges, manufacturers like Rolls-Royce, Pratt & Whitney, and General Electric rose to meet them with next-generation fuel efficiency.
