The 747 was truly monumental in size. The massive airplane required construction of the 200-million-cubic-foot 747 assembly plant in Everett, WA., the world's largest building (by volume). The fuselage of the original 747 was 225 feet 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. The total wing area was larger than a basketball court. Yet, the entire global navigation system weighed less than a modern laptop computer.
