Gianni Caproni built the Ca.60 Transaero in 1921. The fuselage was a giant boat, it had eight wings, eight engines, and the whole looks like something cooked up at Disneyland that you might want to go out in. If it were carefully tethered. It weighed in at 55,000 pounds. After reaching an altitude of 60 feet the flying houseboat took a nosedive and broke up when it hit the water where it sank.
