Flying Cars, Amphibious Vehicles and Other Dual Mode Transports - Green, George W.

Describes the array of vehicles that have been designed to travel not only on land but also in the air or on water - including flying automobiles, roadable aircraft, amphibious vehicles, hovercraft, road-rail trains, and triphibious inventions. Sometimes converted from standard vehicles, sometimes beginning as new designs, these machines have met with varying degrees of success.
