Largest flying boat

The largest flying boat ever constructed was the Hughes H4 Hercules flying boat, more commonly known as the Spruce Goose. The eight-engined 193-tonne aircraft had a wing span of 97.51 m (319 ft 11 in) and a length of 66.65 m (218 ft 8 in). It was raised 21.3 m (70 ft) into the air in a test run of 914 m (3,000 ft), piloted by Howard Hughes (USA, 1905-76), off Long Beach Harbor, California, USA on 2 November 1947, but never flew again.
