Root Causes
Kitty Hawk was Larry Page's personal bet on flying cars. Over 12 years, the company pivoted multiple times — from the Flyer watercraft to the Cora air taxi to the Heaviside personal aircraft. None reached commercial viability despite $600M+ of Page's personal fortune. Novel aviation faces regulatory and infrastructure challenges that make commercial timelines extremely long.
