Tom M sends us the Moller Skycar - a flying car with VTOL capability which has been under development by Paul Moller in Davis, California for over fifty years.  The Skycar never entered production or achieved untethered free flight, and its parent company, Moller International, became dormant around 2017.  The project has consumed over $100 million. Due to the project's failure to deliver along with associated financial issues - Moller has been accused of deliberate fraud - leaving the Skycar's future in limbo.
