From inflatable rescue planes to personal helicopters and road-legal cars so tiny they can be driven indoors, this list showcases some of the most bizarre contraptions of the 19th and 20th centuries.
For every widely produced vehicle or aircraft, there are many prototypes that never made the cut. The interwar and Cold War periods in particular saw many imaginative designs tested out. Some of the featured vehicles performed well enough but never entered mass production, while others were just a little too bizarre to ever work.
