Boeing 777 The Widebody Workhorse at 25

摘要

After just over five years of development, on June 7,1995 the Boeing 777 entered commercial Ⅴ service with United Airlines. Twenty-five years on, it's clear that the 777 is not just any old airliner. Instead, it has become the tried and tested workhorse of many carriers' fleets and, while it may not have the stage presence of a 747 or Airbus A380, it remains one of the most successful commercial aircraft ever built. The Boeing 777, or often the Triple Seven' as it's affectionately known, is a twin-engine widebody developed in the 1990s. The Chicago-based manufacturer originally started in the late 1970s with a tri-jet design, but following the widespread adoption of extended-range twin-engine operational performance standards (ETOPS) for distant legs over water, dropped the plan for a three-engine model. By the late 1980s, it had become clear that a clean-sheet design would be required after it attempted to offer airlines a modified version of its 767, to no avail.
