A Mechanical Marvel Inspired by the Legendary Spruce Goose. Metal Time, the epitome of precision engineering, is proud to introduce the Celestial Hercules — a self-assembly model paying homage to the iconic Hughes H-4 Hercules, commonly known as the Spruce Goose. Crafted entirely from polished stainless steel, this mechanical masterpiece captures the essence of the legendary aircraft’s remarkable history and unique features. Constructed during a time of wartime aluminum restrictions and weight concerns, the aircraft earned the moniker “Spruce Goose” from critics, despite being predominantly made of birch using the Duramold process. Mechanics, humorously referring to it as the “Birch Bitch,” offered a more accurate yet socially unconventional nickname. The Hercules holds the distinction of being the largest flying boat ever built, boasting the widest wingspan of any aircraft until the Scaled Composites Stratolaunch took flight on April 13, 2019.
