The Story Of The Boeing 777-300ER’s Development

This year marks the 21st anniversary of the Boeing 777-300ER’s first flight. We look at how this best-selling aircraft came to be. In the early 1970s, airlines had a choice of three widebody jets for long-haul operations: the four-engined Boeing 747, the three-engined McDonnell Douglas DC-10, or the Lockheed L-1011 TriStar.
