Boeing’s Sci-Fi Foldable Wing Design for New 777s Gets Go-Ahead

U.S. regulators have approved a Buck Rogers makeover of Boeing Co.’s revamped 777 jetliner that will allow the tips of its massive wings to fold upward after landing so the plane can park at existing airport gates. The new wings, the largest ever created by the Chicago-based planemaker, are taking shape as Boeing builds the first of its 777X jetliners in a factory north of Seattle.
