Uber is just one company interested in 'flying cars' - here are 5 others

Uber made a huge hire to advance its flying-car plans.

Mark Moore has left his position as an advanced aircraft engineer at NASA's Langley Research Center to join Uber's flying-car project, dubbed Uber Elevate, Bloomberg first reported Monday.

Uber isn't pursuing a flying car, per se, because it isn't being designed to fly and drive. Instead, Uber, like many other companies, is looking to build an electric, vertical take-off and landing (VTOL) aircraft for shorter urban commutes. Moore published a white paper outlining how electric VTOLs could work in 2010.

But competition is mounting when it comes to the flying-car moonshot - here are 5 other companies working on their own VTOL aircrafts.
