The 747 was the result of the work of some 50,000 Boeing people. Called "the Incredibles," these were the construction workers, mechanics, engineers, secretaries and administrators who made aviation history by building the 747 — the largest civilian airplane in the world — in less than 16 months during the late 1960s.

The 747 was truly monumental in size. The massive airplane required construction of the 200 million-cubic-foot (5.6 million-cubic-meter) 747 assembly plant in Everett, Wash., the world's largest building (by volume). The fuselage of the original 747 was 225 feet (68.5 meters) long; the tail as tall as a six-story building. Pressurized, it carried a ton of air. The cargo hold had room for 3,400 pieces of baggage and could be unloaded in seven minutes.
