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. This is impressive innovation, and it’s going to surprise passengers when the first crop of next-generation Boeing 777s starts parking at airports. Kudos to Boeing for designing wings that fold upward after landing so the plane can park in relatively tight spaces.
