On November 2nd, 1947, the Hughes H-4 Hercules took off for the first time. The test run lasted less than a minute, and it traveled for around a mile. The H-4, erroneously nicknamed the Spruce Goose, was a behemoth; its wing 320-foot wingspan is still the largest of any plane to fly. But that flight was also to be its last; a proof of concept developed by Howard Hughes that was shelved shortly after the test. Now, China's state-owned aircraft maker AVIC has built an amphibious plane that fulfils Hughes' dream of a colossal sea-faring plane.
