A Google Co-Founder Is Secretly Building Flying Cars

Google co-founder Larry Page has been secretly bankrolling companies working on flying cars, according to a new report.

Page, now CEO of Google parent company Alphabet, has contributed over $100 million on secretive personal aviation startup Zee.Aero, Bloomberg reports. He has separately funded another similar startup, called Kitty Hawk, an apparent reference to the site of the Wright brothers’ first flight.

Page did not return Bloomberg’s requests for comment. Google did not immediately return TIME’s request for comment.
