Boeing mechanics load the 111-foot (33.8 m) wing spar for the 747-8 Intercontinental into the assembly tool at the factory in Everett, Wash. The spar is the internal support structure that runs through the full length of the wing. The 747-8 will build on the current 747's capability to fly into most airports worldwide, using the same pilot type ratings, services and most ground support equipment. With a range of 8,000 nautical miles (14,815 km), the 747-8 Intercontinental can connect nearly any major city pair in the world.
