Incredible Flying Cars

Ever since autos have run the roads, inventors have been dreaming of ways to get them up in the air. In the last 100 years, some 300 flying car designs have actually made it off the ground, but none have commercially taken off...not yet anyway. This two-part series explores the turbulent history of the road-to-air vehicle, from early failures to recent breakthroughs in technology and design. Discover how the futuristic world of flying cars is becoming a reality, and explore how this new world of travel may bring a new world of obstacles.

Very interesting. Programed into the DVR to watch. I have that channel and never watched it.
