How big is the Spruce Goose compared to a 747? This question often sparks curiosity among aviation enthusiasts and history buffs alike. The Spruce Goose, also known as the Hughes H-4 Hercules, is one of the most iconic aircraft in history, while the Boeing 747 is a commercial aircraft that has revolutionized air travel. In this article, we will delve into the fascinating comparison between these two giants of aviation.
The Spruce Goose, designed and built by Howard Hughes, was the largest wooden aircraft ever constructed. It first flew on November 2, 1947, and held the title of the world’s largest airplane until the Antonov An-225 Mriya surpassed it in 1988. The aircraft was constructed primarily from birch and other wood materials, hence its name “Spruce Goose.” The 747, on the other hand, is a metal-bodied commercial jetliner that has been in service since 1970.
When comparing the dimensions of the two aircraft, the Spruce Goose is significantly larger. The Spruce Goose had a wingspan of 320 feet (98 meters), making it 40 feet (12 meters) wider than the 747’s wingspan of 230 feet (70 meters). The length of the Spruce Goose was 222 feet (68 meters), while the 747 is 231 feet (70 meters) long. In terms of height, the Spruce Goose stood at 65 feet (20 meters), while the 747 is 63 feet (19 meters) tall.
The Spruce Goose’s payload capacity was also impressive, although it was never fully utilized. It could carry up to 57,000 pounds (26,000 kilograms) of cargo, which is roughly equivalent to the weight of a fully loaded Boeing 737. However, the Spruce Goose was never intended for commercial use, and it only made one test flight before being grounded.
In terms of engine power, the Spruce Goose was equipped with eight Pratt & Whitney R-4360 Wasp Major engines, each producing 3,000 horsepower. The 747, on the other hand, has four Pratt & Whitney JT9D or Rolls-Royce RB211 engines, each producing around 52,000 pounds of thrust. Despite the Spruce Goose’s impressive engine power, it was never able to achieve its full potential due to various technical and logistical challenges.
In conclusion, the Spruce Goose is significantly larger than the Boeing 747 in terms of wingspan, length, and height. However, when it comes to payload capacity and engine power, the 747 is the clear winner. The Spruce Goose remains a testament to the ingenuity and ambition of its creator, Howard Hughes, and its unique place in aviation history.
