The Boeing 777 was designed in consultation with eight leading airlines and was designed to replace the aging McDonnell Douglas DC-10 and Lockheed L1011. It also provided a capacity bridge between the Boeing 767 and the Boeing 747 in that aircraft builders stable of aircraft offerings. The original 777 offering was the Boeing 777 200 version which was followed up in 1997 by the Boeing 777 200ER where the ER stands for Extended Range.

As Boeing deliver their 1,000th 777, they are working hard to ensure the longevity and relevance of this very popular air-frame. The next generation of 777s is on the drawing board and currently is known as the 777X. Many concepts used on the Boeing 787 Dreamliner will be adopted in the design concept of the 777X, including the use of composite materials. Boeing anticipate a 21 per cent improvement in fuel burn with a 16 percent improvement in operating costs. A technology Boeing patented back in 1995 but no one to date has opted for, is the folding wing. The 777X is expected to have a wing span exceeding todays’ 777-300ER by 6 metres (6 feet). The folding wing tips are designed to enable the 777X to use airport gates designed for current 777 variants. They would be locked in place for takeoff and flight. The extended wings allow better fuel economy and speed.
