Fuel-efficient cars are all too common in today’s modern time, but Boeing decided to make a fuel efficient airplane. In this year’s Dubai Airshow, the company unveiled the 777x, their newest airliner. The defining feature of the aircraft are the folding wings which provide an increased wingspan while in the air and hence greater fuel economy. The wings can then be folded to allow easy landing at conventional airports made for smaller aircraft with smaller wingspans.
