This Discovery series celebrates the aviation underdogs, aircraft that carried the loads in Strange Planes: Giants. From the full-bellied dirigibles to passenger jets, large-sized planes have come a long way. Air-inflated craft were popular for a time, even serving in World War I. But, cumbersome construction and navigational limits made them difficult to use. Still, armies needed a way to transport large crews and supplies over enemy-infested waters. Along came the Spruce Goose. Weighing over 400,000 pounds, the enormous plane was an engineering miracle that fulfilled transportation needs.
