The first ever passenger flight of Boeing’s 747-8 Intercontinental landed at Dulles Airport on June 1, shortly after noon. Operated by Lufthansa, the new aircraft will fly the Frankfurt-Dulles route six days a week. New design features of the aircraft include wings with raked-back tips and engines with scalloping that enhances fuel efficiency. At over 250 feet long, the plane is now the longest commercial aircraft built in the United States.
